Views Ethernet interface view Predefined user roles network-admin Usage guidelines CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impacts of this command when you use it in a live network. This command might fail to restore the default settings for some commands for reasons such as command dependencies and system restrictions.
display counters Use display counters to display interface traffic statistics. Syntax display counters { inbound | outbound } interface [ interface-type [ interface-number ] ] Views Any view Predefined user roles network-admin network-operator Parameters inbound: Displays inbound traffic statistics. outbound: Displays outbound traffic statistics. interface-type: Specifies an interface type. interface-number: Specifies an interface number.

Table 2 Command output Field Description Interface Abbreviated interface name.
Usage guidelines If no interface type is specified, this command displays information about all interfaces. If an interface type is specified but no interface number is specified, this command displays information about all interfaces of that type. If both the interface type and interface number are specified, this command displays information about the specified interface. Examples # Display information about Layer 3 interface Ten-GigabitEthernet 1/0/1.

To restore the physical state of the interface, use the undo shutdown command. display packet-drop Use display packet-drop to display information about packets dropped on an interface or multiple interfaces.
Table 6 Command output Field Description Packets dropped due to full GBP or insufficient bandwidth Packets that are dropped because the buffer is used up or the bandwidth is insufficient. Packets dropped due to Fast Filter Process (FFP) Packets that are filtered out. Packets dropped due to STP non-forwarding state Packets that are dropped because STP is in the non-forwarding state. duplex Use duplex to set the duplex mode for an Ethernet interface.
flow-control Use flow-control to enable TxRx mode generic flow control on an Ethernet interface. Use undo flow-control to disable generic flow control on the Ethernet interface. Syntax flow-control undo flow-control Default Generic flow control is disabled on an Ethernet interface. Views Ethernet interface view Predefined user roles network-admin Usage guidelines To implement flow control on a link, enable the generic flow control function at both ends of the link.
Usage guidelines With the flow-control receive enable command configured, an interface can receive, but not send, flow control frames. When the interface receives a flow control frame from its peer, it suspends sending packets to the peer. When traffic congestion occurs on the interface, it cannot send flow control frames to the peer. To handle unidirectional traffic congestion on a link, configure the flow-control receive enable command at one end, and the flow-control command at the other.
Syntax interface interface-type interface-number Views System view Predefined user roles network-admin Parameters interface-type: Specifies an interface type. interface-number: Specifies an interface number. Examples # Enter Ten-GigabitEthernet 1/0/1 interface view. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] jumboframe enable Use jumboframe enable to allow jumbo frames within the specified length to pass through.
link-delay Use link-delay to set the physical state change suppression interval on an Ethernet interface. Use undo link-delay to restore the default. Syntax link-delay delay-time [ mode { up | updown } ] undo link-delay Default Each time the physical link of an interface goes up or comes down, the interface immediately reports the change to the CPU.
loopback Use loopback to perform a loopback test on an Ethernet interface. Use undo loopback to cancel a loopback test on an Ethernet interface. Syntax loopback { external | internal } undo loopback Views Ethernet interface view Predefined user roles network-admin Parameters external: Performs an external loopback test on the Ethernet interface. internal: Performs an internal loopback test on the Ethernet interface.
Views Ethernet interface view Predefined user roles network-admin Parameters bridge: Specifies the Layer 2 mode. route: Specifies the Layer 3 mode. Usage guidelines On the switch, Ethernet interfaces can operate either as Layer 2 Ethernet interfaces (in bridge mode) or Layer 3 Ethernet interfaces (in route mode). After you change the link mode of an Ethernet interface, all the settings of the Ethernet interface are restored to their defaults under the new link mode.
To use the PFC feature on a link, make sure it is enabled on both ends of the link. An interface processes PFC pause frames only when PFC is enabled on it. The state of the PFC function is co-determined by the PFC configurations on the local port and on the peer. In Table 7, the first line lists the PFC configuration on the local port, the first column lists the PFC configuration on the peer, and enabled and disabled are the two possible negotiation results.
Usage guidelines PFC performs flow control based on 802.1p priorities. With PFC enabled, an interface requires its peer to suspend sending packets with certain 802.1p priorities when congestion occurs. By decreasing the transmission rate, PFC helps avoid packet loss. You can enable PFC for certain 802.1p priorities at the two ends of a link. When network congestion occurs, the local switch checks the PFC status for the 802.1p priority carried in each arriving packet. • If PFC is enabled for the 802.
the range specified by the dot1p-list argument, the port preferentially sends the packet. For more information about the 802.1p-local priority mapping table, see ACL and QoS Configuration Guide. If you configure the flow control or flow-control receive enable command on a PFC-enabled port, the PFC configuration takes effect, and the configuration of the flow control or flow-control receive enable command is ignored. The latter takes effect on the port only when PFC is disabled on it.
• display counters interface • display counters rate interface reset packet-drop interface Use reset packet-drop interface to clear the dropped packet statistics on an interface or multiple interfaces. Syntax reset packet-drop interface [ interface-type [ interface-number ] ] Views User view Predefined user roles network-admin Parameters interface-type: Specify an interface type.
Usage guidelines You might need to shut down and then bring up an Ethernet interface to make some interface configurations take effect. Examples # Shut down and then bring up Ten-GigabitEthernet 1/0/1. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] shutdown [Sysname-Ten-GigabitEthernet1/0/1] undo shutdown speed Use speed to set the speed of an Ethernet interface. Use undo speed to restore the default.
GE copper ports do not support the 10000 or 40000 keyword. Examples # Configure Ten-GigabitEthernet 1/0/1 to autonegotiate the speed. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] speed auto using fortygige Use using fortygige to combine four 10-GE interfaces that are split from a 40-GE interface into a 40-GE interface. Use undo using fortygige to cancel the configuration.
Use undo using tengige to cancel the configuration. Syntax using tengige undo using tengige Default A 40-GE interface is used as a single interface, and is not automatically split. Views 40-GE interface view Predefined user roles network-admin Usage guidelines You can use a 40-GE interface as a single interface. You can also split a 40-GE interface into four 10-GE interfaces to improve the port density, reduce the cost, and improve the network flexibility.
Views Layer 2 Ethernet interface view Predefined user roles network-admin Parameters ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. This argument is in the range of 0 to 100. The smaller the percentage, the less broadcast traffic is allowed to pass through. pps max-pps: Specifies the maximum number of broadcast packets that the interface can forward per second. The max-pps argument (in pps) is in the range of 1 to 1.4881 × the maximum interface rate.
display storm-constrain Use display storm-constrain to display storm control settings and statistics. Syntax display storm-constrain [ broadcast | multicast | unicast ] [ interface interface-type interface-number ] Views Any view Predefined user roles network-admin network-operator Parameters broadcast: Displays broadcast storm control settings and statistics. multicast: Displays multicast storm control settings and statistics. unicast: Displays unknown unicast storm control settings and statistics.
Field Description Storm control threshold unit: Unit • pps. • kbps. • percentage. CtrlMode Protective action (block or shutdown) taken on the port when the upper threshold is reached. N/A indicates that no protective action is configured. Packet forwarding status: Status • forwarding—The port is forwarding traffic correctly. • shutdown—The port has been shut down. • block—The port drops the type of traffic.
mdi: Specifies that pins 1 and 2 are transmit pins and pins 3 and 6 are receive pins. mdix: Specifies that pins 1 and 2 are receive pins and pins 3 and 6 are transmit pins. Examples # Set Ten-GigabitEthernet 1/0/1 to operate in MDI mode. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] mdix-mode mdi multicast-suppression Use multicast-suppression to enable multicast storm suppression and set the multicast storm suppression threshold.
When you configure the multicast suppression threshold in kbps, the switch automatically uses a multiple of 64 as the threshold. If you configure a value less than 64, the switch sets the threshold to 64 kbps. If you configure a value greater than 64, the switch sets the threshold to a multiple of 64 which is greater than the configured value and is nearest to the value than other multiples. Examples # Set the multicast storm suppression threshold to 10000 kbps on Ten-GigabitEthernet 1/0/1.
upperlimit: Sets the upper threshold, in pps, kbps, or percentage. lowerlimit: Sets the lower threshold, in pps, kbps, or percentage. Usage guidelines After you configure this command, the device collects the statistics of a particular type of traffic at the specified interval, which can be configured by using the storm-constrain interval command.
Default No action is taken on an Ethernet interface when a type of traffic exceeds the upper storm control threshold. Views Layer 2 Ethernet interface view Predefined user roles network-admin Parameters block: Blocks this type of traffic, while forwarding other types of traffic. Even though the interface does not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected dropping below the lower threshold, the port begins to forward the traffic.
system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] storm-constrain enable log storm-constrain enable trap Use storm-constrain enable trap to enable an Ethernet interface to send storm control threshold event traps. Use undo storm-constrain enable trap to disable trap sending.
Usage guidelines The interval set by the storm-constrain interval command is specific to storm control. To set the statistics polling interval of an interface, use the flow-interval command. For network stability, use the default or a higher polling interval. Examples # Set the traffic statistics polling interval of the storm control module to 60 seconds.
Both the storm-constrain and unicast-suppression can suppress unicast storm on a port. The storm-constrain command uses software to suppress unicast traffic, and it affects the device performance to a certain extent. The unicast-suppression command use the chip to physically suppress unicast traffic, and it has less influence on the device performance than the storm-constrain command. Do not configure the storm constrain command and the unicast-suppression command at the same time.
system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] virtual-cable-test Cable status: normal, 38 metre(s) Pair Impedance mismatch: yes Pair skew: 38 ns Pair swap: Pair polarity: swap Insertion loss: 12 db Return loss: 11 db Near-end crosstalk: 13 db Table 10 Command output Field Description Cable status: • Normal—The cable is in good condition. Cable status • Abnormal—The cable is abnormal. • Abnormal (open)—An open circuit is detected.
Usage guidelines Set an appropriate MTU to avoid fragmentation. The MTU for the interface applies to only packets that are sent to the CPU for forwarding by software, for example, the packets that are sourced from or destined to the interface. As the MTU size decreases, the number of fragments grows. When you set the MTU for an interface, you should consider QoS queue lengths (for example, the default FIFO queue length is 75) to prevent a too small MTU from causing packet drops in QoS queuing.
Loopback and null interface commands default Use default to restore the default settings for a loopback or null interface. Syntax default Views Loopback interface view, null interface view Predefined user roles network-admin Usage guidelines CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impacts of this command before using it on a live network.
Predefined user roles network-admin Parameters text: Specifies an interface description, a string of 1 to 80 characters. Usage guidelines Configure a description for an interface for easy identification and management purposes. You can use the display interface command to view the configured description.

Field Description Physical link state of the interface: • UP—The link is up. • DOWN—The link is physically down. Link • ADM—The link has been administratively shut down. To recover its physical state, run the undo shutdown command. • Stby—The interface is a standby interface. Protocol connection state of the interface: • UP. Protocol • DOWN. • UP(s)—The link of the interface is an on-demand link or not present at all. Description Interface description configured by using the description command.
If the null keyword is not specified, the command displays information about all interfaces of the device. If the null keyword is specified but the 0 keyword is not specified, the command displays information about interface Null 0, because the device has only one null interface Null 0. Examples # Display detailed information about interface Null 0.
Default No loopback interface exists. Views System view Predefined user roles network-admin Parameters interface-number: Specifies a loopback interface by its number in the range of 0 to 1023. Usage guidelines The physical layer state and link layer protocols of a loopback interface are always up unless the loopback interface is manually shut down.
reset counters interface loopback Use reset counters interface loopback to clear the statistics on the specified or all loopback interfaces. Syntax reset counters interface [ loopback [ interface-number ] ] Views User view Predefined user roles network-admin Parameters interface-number: Specifies a loopback interface by its number, which can be the number of any existing loopback interface. If you do not specify the interface-number argument, the command clears the statistics on all loopback interfaces.
Examples # Clear the statistics on interface Null 0. reset counters interface null 0 Related commands display interface null shutdown Use shutdown to shut down a loopback interface. Use undo shutdown to bring up a loopback interface. Syntax shutdown undo shutdown Default A loopback interface is up.

Syntax interface range interface-list Views System view Predefined user roles network-admin Parameters interface-list: Specifies an interface list in the format of interface-list = { interface-type interface-number [ to interface-type interface-number ] }&<1-5>. The interface-type interface-number argument specifies an interface by its type and number.
Examples # Shut down interfaces Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/24, VLAN interface 2. system-view [Sysname] interface range ten-gigabitethernet 1/0/1 to ten-gigabitethernet 1/0/24 vlan-interafce 2 [Sysname-if-range] shutdown interface range name Use interface range name name interface interface-list to create an interface range, configure a name for the interface range, and enter the interface range view.
To view the member interfaces of an interface range, use the display current-configuration | include "interface range" command. To bulk configure interfaces, follow these guidelines: • If you cannot enter the view of an interface by using the interface interface-type interface-number command, do not configure the interface as the first interface in the interface range. • Do not assign an aggregate interface and any of its member interfaces to an interface range at the same time.
MAC address table commands The MAC address table contains only Layer 2 Ethernet interfaces and Layer 2 aggregate interfaces. This document covers the configuration of unicast MAC address entries, including static, dynamic, blackhole, and multiport unicast MAC address entries. For more information about configuring static multicast MAC address entries, see IP Multicast Configuration Guide. For more information about MAC address table configuration in VPLS, see MPLS Configuration Guide.

dynamically learned entries, using manually configured static MAC address entries prevents hackers from using forged MAC addresses to steal data. The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC address entries, however, are lost upon reboot regardless of whether you save the configuration. Examples # Add a static entry for MAC address 000f-e201-0101 on interface Ten-GigabitEthernet 1/0/1 that belongs to VLAN 2.
Parameters blackhole: Specifies blackhole MAC address entries. The packets whose source or destination MAC addresses match blackhole MAC address entries are dropped. mac-address: Specifies a MAC address in the format of H-H-H. When entering a MAC address, you can omit the leading zeros in each H section. For example, enter f-e2-1 for 000f-00e2-0001. vlan vlan-id: Specifies an existing VLAN to which the interface belongs. The value range for the vlan-id argument is 1 to 4094.
Use undo mac-address mac-learning enable to disable MAC address learning. Depending on the view that you entered, you can disable it globally, on an interface, or on a VLAN. Syntax mac-address mac-learning enable undo mac-address mac-learning enable Default MAC address learning is enabled.

Usage guidelines This command takes effect on only known unicast packets and can change the global load sharing criteria for known unicast packets. Broadcast packets, multicast packets, and unknown unicast packets always use the default global load sharing criteria. The load sharing criteria that you configure overwrite the previous criteria. If unsupported load sharing criteria are configured, an error prompt appears.
Usage guidelines With this feature, when you restart a card that contains Selected ports, traffic can be redirected to other cards. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic. (In standalone mode.) With this feature, when you restart an IRF member device or its card that contains Selected ports, traffic can be redirected to other IRF member devices or other cards. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic.
flexible: Performs load sharing in link aggregation groups flexibly based on packet types (Layer 2, IPv4, IPv6, or MPLS for example). Usage guidelines This command takes effect on only unicast packets and can change the load sharing criteria for known unicast packets. Broadcast packets, multicast packets, and unknown unicast packets always use the default load sharing criteria. The load sharing criteria that you configure overwrites the previous criteria.
Description Use link-aggregation load-sharing mode local-first to enable local-first load sharing for link aggregation. Use undo link-aggregation load-sharing mode local-first to disable local-first load sharing for link aggregation. After you disable local-first load sharing for link aggregation, the packets to be forwarded out of an aggregate interface will be load-shared among all Selected ports of the aggregate interface on all IRF member devices.

When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that interface. When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate interface. When the setting is configured on a member port in an aggregation group, it takes effect only after the port leaves the aggregation group. Examples # Enable digest snooping on Ten-GigabitEthernet 1/0/1 and then globally.
• When the private standard is selected for path cost calculation, the value range for the cost argument is 1 to 200000. Usage guidelines Path cost is an important factor in spanning tree calculation. Setting different path costs for a port in MSTIs allows VLAN traffic flows to be forwarded along different physical links, which results in VLAN-based load balancing. The path cost setting of a port can affect the role selection of the port.
Typically, configuration BPDUs from other devices cannot reach an edge port, because the edge port does not connect to any other device. If a port receives a configuration BPDU when the BPDU guard function is disabled, the port functions as a non-edge port, even if you configure it as an edge port. On a port, the loop guard function, the root guard function, and the edge port setting are mutually exclusive, and the one that is configured first takes effect.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate interface. When the setting is configured on a member port in an aggregation group, it takes effect only after the port leaves the aggregation group. Examples # In MSTP mode, disable the spanning tree feature on port Ten-GigabitEthernet 1/0/1.

Syntax stp max-hops hops undo stp max-hops Default The maximum number of hops for an MST region is 20. Views System view Predefined user roles network-admin Parameters hops: Sets the maximum hops in the range of 1 to 40. Examples # Set the maximum hops of the MST region to 35.
when Device C receives an STP BPDU transparently transmitted by Device B, the receiving port transits to the STP mode. If you configure Device B to run RSTP or MSTP with Device C, perform mCheck operations on the ports that connect Device B and Device C. The device operates in STP, RSTP, or MSTP mode depending on the spanning tree mode setting. The stp mcheck command is effective only when the device operates in MSTP or RSTP mode.

Syntax stp timer-factor factor undo stp timer-factor Default The timeout factor of a device is set to 3. Views System view Predefined user roles network-admin Parameters factor: Sets the timeout factor in the range of 1 to 20. Usage guidelines Timeout interval = timeout factor × 3 × hello time. After the network topology is stabilized, each non-root-bridge device forwards configuration BPDUs to the surrounding devices at the interval of hello time to determine whether any link is faulty.
Views Layer 2 Ethernet interface view, Layer 2 aggregate interface view Predefined user roles network-admin Parameters limit: Sets the maximum number of BPDUs the ports can send within each hello time. The value range is 1 to 255. Usage guidelines A larger maximum transmission rate value requires more system resources. An appropriate maximum transmission rate setting can prevent spanning tree protocols from using excessive bandwidth resources during network topology changes.
This command maps each VLAN to the MSTI whose ID is (VLAN ID – 1) % modulo + 1, where (VLAN ID – 1) % modulo is the modulo operation for (VLAN ID – 1). If the modulo value is 15, then VLAN 1 is mapped to MSTI 1, VLAN 2 to MSTI 2, …, VLAN 15 to MSTI 15, VLAN 16 to MSTI 1, and so on. Examples # Map VLANs to MSTIs as per modulo 8.

Usage guidelines A VLAN interface that was shut down with the shutdown command remains in DOWN (Administratively) state until you bring it up, regardless of how the state of the ports in the VLAN changes. Before you configure parameters for a VLAN interface, shut down the VLAN interface with the shutdown command to prevent the configurations from affecting the network.
You cannot create or remove VLANs that are reserved for specific functions. You cannot use the undo vlan command to delete a dynamic VLAN, a VLAN with a QoS policy applied, or a VLAN locked by an application. To delete such a VLAN, first remove the configuration from the VLAN. Examples # Create VLAN 2 and enter its view. system-view [Sysname] vlan 2 [Sysname-vlan2] # Create VLAN 4 through VLAN 100.
