Ethernet interface commands The switch has one built-in MPU. The slot number of this MPU is fixed at 0. Unless otherwise stated, the term "card" in this document refers to both the MPU and LPUs. Common Ethernet interface commands bandwidth Use bandwidth to configure the expected bandwidth of an interface. Use undo bandwidth to restore the default. Syntax bandwidth bandwidth-value undo bandwidth Default The expected bandwidth (in kbps) is the interface baud rate divided by 1000.
default Use default to restore the default settings for an Ethernet interface. Syntax default 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 or system restrictions.
Parameters text: Specifies the interface description, a case-sensitive string of 1 to 255 characters. Examples # Change the description of interface FortyGigE 1/0/1 to lanswitch-interface. system-view [Sysname] interface fortygige 1/0/1 [Sysname-FortyGigE1/0/1] description lanswitch-interface display counters Use display counters to display interface traffic statistics.

Field Description If the speed of an interface is automatically negotiated, its speed attribute includes the autonegotiation flag, indicated by the letter a in parentheses. Speed or Duplex: (a)/A - auto; H half; F – full If the duplex mode of an interface is automatically negotiated, its duplex mode attribute includes the following options: • (a)/A—Autonegotiation. • H—Half negotiation. • F—Full negotiation. Type: A - access; T - trunk; H – hybrid Link type options for Ethernet interfaces.
Field Description Cause for the physical link state of an interface to be DOWN: • Administratively—The port is manually shut down with the shutdown command. To restore the physical state of the interface, use the undo shutdown command. • DOWN ( Link-Aggregation interface down )—When an aggregate interface is shut down, the physical state of all member ports of the aggregate interface becomes DOWN, and the Cause field displays DOWN ( Link-Aggregation interface down ).
interface-number: Specifies an interface number. If you specify an interface type only, this command displays information about dropped packets on the specified type of interfaces. summary: Displays the summary of dropped packets on all interfaces. Examples # Display information about dropped packets on FortyGigE 1/0/1.
Examples # Configure interface FortyGigE 1/0/1 to operate in full duplex mode. system-view [Sysname] interface fortygige 1/0/1 [Sysname-FortyGigE1/0/1] duplex full 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.
Default Rx flow control is disabled on Ethernet interfaces. Views Ethernet interface view Predefined user roles network-admin 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.
jumboframe enable Use jumboframe enable to allow jumbo frames within the specified length to pass through. Use undo jumboframe enable to prevent jumbo frames from passing through. Syntax jumboframe enable [ value ] undo jumboframe enable Default The device allows jumbo frames within 12288 bytes to pass through. Views Ethernet interface view Predefined user roles network-admin Parameters value: Sets the maximum length of Ethernet frames that are allowed to pass through.
Parameters msec: Enables the physical state change suppression interval to be accurate to milliseconds. If you do not specify this keyword, the suppression interval is accurate to seconds. delay-time: Sets the physical state change suppression interval on the Ethernet interface. A value of 0 indicates that physical state changes are immediately reported to the CPU and are not suppressed. • If you do not specify the msec keyword, the value range for this argument is 0 to 30 seconds.
undo port link-mode Default Ethernet interfaces operate in bridge mode. 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 or Layer 3 Ethernet interfaces (you can use commands to set the link mode to bridge or route).
Usage guidelines The state of the PFC function is co-determined by the PFC configurations on the local port and on the peer. In Table 8, 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. Table 8 PFC configurations and negotiation results Local (right) enable auto Default enable Enabled Enabled. Disabled auto Enabled • Enabled if negotiation succeeds.
Usage guidelines You can enable PFC for certain 802.1p priorities at the two ends of a link. When network congestion occurs, the local device checks the PFC status for the 802.1p priority carried in each arriving packet. The device processes the packet depending on the PFC status as follows: • If PFC is enabled for the 802.1p priority, the local device accepts the packet and sends a PFC pause frame to the peer. The peer stops sending packets carrying this 802.
reset counters interface Use reset counters interface to clear the Ethernet interface statistics. Syntax reset counters interface [ interface-type [ interface-number ] ] Views User view Predefined user roles network-admin Parameters interface-type: Specifies an interface type. interface-number: Specifies an interface number.

Related commands mac-address timer display mac-address mac-learning Use display mac-address mac-learning to verify whether MAC address learning has been enabled globally or on an interface.
Table 16 Command output Field Description Global MAC address learning status: Global MAC address learning status • Enabled. • Disabled. MAC address learning status of an interface: Learning Status • Enabled. • Disabled. Related commands mac-address mac-learning enable display mac-address statistics Use display mac-address statistics to display MAC address table statistics.
Table 17 Command output Field Description Dynamic Unicast Address (Learned) Count Number of dynamic unicast MAC address entries triggered by packets. Dynamic Unicast Address (Security-service-defined) Count Number of dynamic unicast MAC address entries triggered by the security service. Static Unicast Address (User-defined) Count Number of static unicast MAC address entries added by users.
mac-address: Specifies a MAC address in the format of H-H-H, excluding multicast and all-zero MAC addresses. 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 specified interface belongs. The value range for the vlan-id argument is 1 to 4094.
Syntax mac-address { dynamic | static } mac-address interface interface-type interface-number vlan vlan-id mac-address blackhole mac-address vlan vlan-id mac-address multiport mac-address interface interface-list vlan vlan-id undo mac-address [ [ dynamic | static ] mac-address interface interface-type interface-number vlan vlan-id ] undo mac-address [ blackhole | dynamic | static ] [ mac-address ] vlan vlan-id undo mac-address [ dynamic | static ] interface interface-type interface-number undo mac-address m
To drop the packets with the specified source MAC addresses or destination MAC addresses, you can configure blackhole MAC address entries. A multiport unicast MAC address entry is used to send frames with a specific destination MAC address out of multiple ports. When you execute this command for the first time, the command adds a MAC address entry. When you execute the command again with the same MAC address and VLAN but with different interfaces, this command adds the specified interfaces for this entry.
Predefined user roles network-admin Usage guidelines To prevent the MAC address table from becoming saturated, you can disable MAC address learning. For example, a number of packets with different source MAC addresses reaching a device can affect the MAC address table update. You can disable MAC address learning to avoid such attacks, but the following guidelines apply: • You can disable MAC address learning on a per-interface basis.
Views System view Predefined user roles network-admin Usage guidelines If ports on different cards of the same device or of different IRF member devices are selected ports from the same aggregation group, MAC address entries are synchronized among these cards regardless of whether MAC address synchronization is enabled. For more information about aggregation groups, see Layer 2—LAN Switching Configuration Guide. The MAC address table size might vary with different cards.
Follow these guidelines to set the aging timer appropriately: • A long aging interval causes the MAC address table to retain outdated entries and fail to accommodate the most recent network changes. • A short aging interval results in removal of valid entries and unnecessary broadcasts that affect device performance. Examples # Set the aging time to 500 seconds for dynamic MAC address entries.
MAC Information commands mac-address information enable (interface view) Use mac-address information enable to enable MAC Information on an interface. Use undo mac-address information enable to disable MAC Information on an interface. Syntax mac-address information enable { added | deleted } undo mac-address information enable { added | deleted } Default MAC Information is disabled on an interface.
undo mac-address information enable Default MAC Information is disabled globally. Views System view Predefined user roles network-admin Usage guidelines Before you enable MAC Information on an interface, enable MAC Information globally. Examples # Enable MAC Information globally.
mac-address information mode Use mac-address information mode to set the MAC Information mode (to use syslog messages or SNMP notifications) to send MAC address changes. Use undo mac-address information mode to restore the default. Syntax mac-address information mode { syslog | trap } undo mac-address information mode Default SNMP notifications are used to send MAC address changes.
Usage guidelines If the MAC Information queue length is 0, the device sends a syslog message or SNMP notification immediately after learning or deleting a MAC address. If it is not 0, the device stores MAC address changes in the queue: • When the timer set for sending syslog messages or SNMP notifications does not expire, the device overwrites the last piece of information written into the queue with the new MAC address change if the queue has been exhausted.
Ethernet link aggregation commands bandwidth Use bandwidth to configure the expected bandwidth for an interface. Use undo bandwidth to restore the default. Syntax bandwidth bandwidth-value undo bandwidth Default The expected bandwidth (in kbps) is the interface baud rate divided by 1000. Views Layer 2 aggregate interface view Predefined user roles network-admin Parameters bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps.
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 execute it on a live network. This command might fail to restore the default settings for some commands for reasons such as command dependencies and system restrictions. Use the display this command in interface view to identify these commands, and then use their undo forms or follow the command reference to individually restore their default settings.

The value range for the instance-id argument is 0 to 4094, and the value 0 represents the CIST. cost: Specifies the path cost of the port, with an effective range that depends on the path cost calculation standard that is adopted.
Views Layer 2 Ethernet interface view, Layer 2 aggregate interface view Predefined user roles network-admin Usage guidelines If a port directly connects to a user terminal rather than to another device or a shared LAN segment, this port is regarded as an edge port. In case the network topology changes, an edge port does not cause a temporary loop. You can enable the port to transit to the forwarding state rapidly by configuring it as an edge port.
Predefined user roles network-admin Usage guidelines When you enable the spanning tree feature, the device operates in STP, RSTP, or MSTP mode, depending on the spanning tree mode setting. When you enable the spanning tree feature, the device dynamically maintains the spanning tree status of VLANs, based on received configuration BPDUs. When you disable the spanning tree feature, the device stops maintaining the spanning tree status.

Predefined user roles network-admin Parameters time: Sets the hello time in centiseconds in the range of 100 to 1000 in increments of 100 (as in 100, 200, 300). Usage guidelines Hello time is the time interval at which spanning tree devices send configuration BPDUs to maintain the spanning tree. If a device fails to receive configuration BPDUs within the set period of time, a new spanning tree calculation process is triggered due to timeout. HP recommends not setting the hello time with this command.
Usage guidelines In the CIST of an MSTP network, the device determines whether a configuration BPDU received on a port has expired based on the max age timer. If the configuration BPDU has expired, a new spanning tree calculation process starts. The max age timer takes effect only on the CIST (or MSTI 0). HP recommends not setting the max age timer with this command.
