MAC address table configuration commands The MAC address table can contain only Layer 2 Ethernet ports. This document covers only the static, dynamic, and destination blackhole MAC address entries. display mac-address Use display mac-address to display information about the MAC address table.
--- 1 mac address(es) found --- Table 1 Command output Field Description MAC ADDR MAC address. VLAN ID ID of the VLAN to which the MAC address belongs. State of a MAC address entry: STATE PORT INDEX • • • • Config static—Static entry manually configured by the user. Config dynamic—Dynamic entry manually configured by the user. Learned—Entry learned by the device. Blackhole—Destination blackhole entry. Number of the port corresponding to the MAC address.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters. Examples # Display the aging time of dynamic entries in the MAC address table. display mac-address aging-time Mac address aging time: 300s The output shows that the aging time of dynamic entries in the MAC address table is 300 seconds.
Table 2 Command output Field Description Mac-address learning status of the switch Global MAC address learning status (enabled or disabled). PortName Port name. Learning Status MAC address learning status (enabled or disabled) for a port. mac-address (interface view) Use mac-address to add or modify a MAC address entry on a specified interface. Use undo mac-address to remove a MAC address entry on the interface.
mac-address (system view) Use mac-address to add or modify a MAC address entry. Use undo mac-address to remove one or all MAC address entries.
The MAC address entries configuration cannot survive a reboot unless you save it. However, the dynamic MAC address entries are lost at next reboot regardless of whether you save the configuration or not. Examples # Add a static entry for MAC address 000f-e201-0101. All frames destined to this MAC address are sent out of port Ethernet 1/1 that belongs to VLAN 2.
mac-address max-mac-count Use mac-address max-mac-count count to configure the maximum number of MAC addresses that can be learned on a port. Use mac-address max-mac-count disable-forwarding to disable the device from forwarding frames with unknown source MAC addresses after the number of learned MAC addresses reaches the upper limit. Use undo mac-address max-mac-count to restore the default maximum number of MAC addresses that can be learned on an Ethernet port.
Command MSR9 00 MSR93X MSR20 -1X MSR 20 MSR30 MSR50 MSR1000 Yes Available on only a MIM-FSW module. mac-address max-mac-co unt No No No No The count argument is in the range of: • 0 to 8191 for MSR30-11E and MSR30-11F. Yes Available on only a FIC-FSW module. The count argument is in the range of 0 to 4096. Yes The count argument is in the range of 0 to 4096 • 0 to 4096 for others. Examples # Set the maximum number of MAC addresses that can be learned on port Ethernet 1/1 to 600.
Parameters aging seconds: Sets an aging timer for dynamic MAC address entries, in the range of 10 to 4080 seconds. no-aging: Sets dynamic MAC address entries not to age. Usage guidelines 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 latest network changes.
Layer 2 forwarding configuration commands display mac-forwarding statistics Use display mac-forwarding statistics to display Layer 2 forwarding statistics. Syntax display mac-forwarding statistics [ interface interface-type interface-number ] [ | { begin | exclude | include } regular-expression ] Views Any view Default command level 1: Monitor level Parameters interface interface-type interface-number: Displays the statistics of an interface specified by its type and number.

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.
• Each Unicode character takes the space of two regular characters. • To use Unicode characters or symbols in an interface description, install the specific input method editor and log in to the device through remote login software that supports the character type.
|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide. begin: Displays the first line that matches the specified regular expression and all lines that follow. exclude: Displays all lines that do not match the specified regular expression. include: Displays all lines that match the specified regular expression. regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Table 4 Command output Field Description Physical state of a VLAN-interface: • DOWN (Administratively)—The administrative state of the VLAN-interface is down, because it has been shut down with the shutdown command. Vlan-interface2 current state • DOWN—The administrative sate of the VLAN-interface is up, but its physical sate is down. The VLAN corresponding to this interface does not contain any physical port in the UP state (possibly because the ports are not well connected or the lines have failed).
Field Description Link layer state of an interface: Link: ADM - administratively down; Stby - standby • ADM—The interface has been administratively shut down. To recover its physical state, perform the undo shutdown command. • Stby—The interface is operating as a standby interface. To see the main interface, use the display standby state command.
reserved: Displays information about the reserved VLANs. Protocol modules determine which VLANs are reserved VLANs, according to function implementation, and reserved VLANs serve protocol modules. You cannot configure reserved VLANs. static: Displays the number of static VLANs and the ID for each static VLAN. The static VLANs are manually created. |: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.
Field Description Subnet Mask Subnet mask of the primary IP address. This is available only when an IP address is configured for the VLAN-interface. Tagged Ports Ports through which VLAN packets are sent tagged. Untagged Ports Ports through which VLAN packets are sent untagged. Related commands vlan interface vlan-interface Use interface vlan-interface to create a VLAN-interface and enter its view or enter the view of an existing VLAN-interface.
Syntax ip address ip-address { mask | mask-length } [ sub ] undo ip address [ ip-address { mask | mask-length } [ sub ] ] Default No IP address is assigned to any VLAN-interface. Views VLAN-interface view Default command level 2: System level Parameters ip-address: Specifies an IP address in dotted decimal notation. mask: Specifies a subnet mask in dotted decimal notation. mask-length: Sets the number of consecutive 1s in the subnet mask, in the range of 0 to 32.
undo mac-address Views VLAN-interface view Default command level 2: System level Parameters mac-address: Specifies a MAC address in the format of H-H-H. Usage guidelines VLAN-interfaces are virtual interfaces that are manually created and removed. Upon creation, a VLAN-interface borrows the MAC address of a physical interface on the device. For this reason, all VLAN-interfaces on a device share the same MAC address.
name Use name to configure a name for the VLAN. Use undo name to restore the default name of the VLAN. Syntax name text undo name Default The name of a VLAN is VLAN vlan-id, which is its VLAN ID. For example, the default name of VLAN 100 is VLAN 0100. Views VLAN view Default command level 2: System level Parameters text: Specifies a VLAN name, a string of 1 to 32 characters.
Views User view Default command level 2: System level Parameters vlan-interface-id: Specifies a VLAN-interface number. Usage guidelines Before collecting the traffic statistics within a specific period of time on an interface, clear the existing statistics first. If the vlan-interface-id argument is not specified, this command clears the statistics of all VLAN-interfaces. If the vlan-interface-id argument is specified, this command clears the statistics of the specified VLAN-interface.
You can shut down a failed interface with the shutdown command and then bring it up with the undo shutdown command to see if it recovers. In a VLAN, the state of any Ethernet port is independent of the state of the VLAN-interface. Examples # Shut down VLAN-interface 2, and then cancel the action of shutting it down.
• Protocol reserved VLANs • Voice VLANs • Management VLANs • Dynamic VLANs Examples # Create VLAN 2, and enter VLAN 2 view. system-view [Sysname] vlan 2 [Sysname-vlan2] # Create VLAN 4 through VLAN 100. system-view [Sysname] vlan 4 to 100 Please wait............. Done.

Voice VLAN configuration commands The following matrix shows the voice VLAN configuration commands and router compatibility: Commands Voice VLAN configuration commands MSR90 0 No MSR93X No MSR20-1 X No MSR20 MSR30 MSR50 MSR10 00 No Available only on fixed Layer 2 Ethernet interfaces of MSR30-11E and MSR30-11F routers and on routers installed with MIM and XMIM Layer 2 switching modules Available only on routers installed with FIC Layer 2 switching modules Yes display voice vlan oui Use displa
Usage guidelines OUI addresses in this document are used to determine whether a received packet is a voice packet. They are the results of the AND operation of the two arguments mac-address and oui-mask in the voice vlan mac-address command. Examples # Display the supported OUI addresses and their masks and descriptions.
Examples # Display voice VLAN configurations. display voice vlan state Maximum of Voice VLANs: 128 Current Voice VLANs: 2 Voice VLAN security mode: Security Voice VLAN aging time: 1440 minutes Voice VLAN enabled port and its mode: PORT VLAN MODE ----------------------------------------------Ethernet1/1 2 AUTO Ethernet1/2 3 AUTO Table 9 Command output Field Description Maximum of Voice VLANs Maximum number of voice VLANs supported by the system.
Default command level 2: System level Parameters minutes: Sets the voice VLAN aging time in the range of 5 to 43200 minutes. Usage guidelines When a port in automatic voice VLAN assignment mode receives a voice packet, the system decides whether to assign the port to the voice VLAN based on the source MAC address of the voice packet. Upon assigning the port to the voice VLAN, the system starts the aging timer.
voice vlan mac-address Use voice vlan mac-address to allow packets carrying the specified OUI address to pass through. Use undo voice vlan mac-address to prohibit packets carrying the specified OUI address from passing through. Syntax voice vlan mac-address mac-address mask oui-mask [ description text ] undo voice vlan mac-address oui Default The system is configured with the default OUI addresses. You can remove the default OUI addresses, and then add recognizable OUI addresses manually.
Examples # Add a recognizable OUI address 1234-1200-0000 by specifying the MAC address as 1234-1234-1234 and the mask as fff-ff00-0000, and configure its description string as PhoneA. system-view [Sysname] voice vlan mac-address 1234-1234-1234 mask ffff-ff00-0000 description PhoneA Related commands display voice vlan oui voice vlan mode auto Use voice vlan mode auto to configure the port to operate in automatic voice VLAN assignment mode.
Views System view Default command level 2: System level Usage guidelines When you enable the security mode for a voice VLAN, only voice traffic can be transmitted in the voice VLAN. The device matches the source MAC addresses of the packets against the supported OUI addresses to determine whether they are voice traffic and filters all non-voice traffic, guaranteeing high priority and high quality for voice traffic.
Spanning tree configuration commands active region-configuration Use active region-configuration to activate your MST region configuration. Syntax active region-configuration Views MST region view Default command level 2: System level Usage guidelines When you configure MST region–related parameters, MSTP launches a new spanning tree calculation process that might cause network topology instability. This is most likely to occur when you configure the VLAN-to-instance mapping table.
Views MST region view Default command level 2: System level Usage guidelines Two or more spanning tree devices belong to the same MST region only if they are configured with the same format selector (0 Not configurable), MST region name, MST region revision level, and the same VLAN-to-instance mapping entries in the MST region, and if they are connected through a physical link. HP recommends that you use this command to determine whether the MST region configurations to be activated are correct.

Related commands • display stp region-configuration • check region-configuration • active region-configuration region-name Use region-name to configure the MST region name. Use undo region-name to restore the default MST region name. Syntax region-name name undo region-name Default The MST region name of a device is its MAC address. Views MST region view Default command level 2: System level Parameters name: Specifies the MST region name, a string of 1 to 32 characters.
reset stp Use reset stp to clear the MSTP statistics information. Syntax reset stp [ interface interface-list ] Views User view Default command level 1: Monitor level Parameters interface interface-list: Clears the MSTP statistics of the ports specified in the format of interface-list = { interface-type interface-number [ to interface-type interface-number ] }&<1-10>, where &<1-10> indicates that you can specify up to 10 ports or port ranges.
Usage guidelines The MSTP revision level, the MST region name, and the VLAN-to-instance mapping table of a device determine the device's MST region. When the MST region name and VLAN-to-instance mapping table are both the same for two MST regions, they can still be differentiated by their MSTP revision levels. After configuring this command, run the active region-configuration command to activate the configured MST region level. Examples # Set the MSTP revision level of the MST region to 5.
Use undo stp bridge-diameter to restore the default. Syntax stp bridge-diameter diameter undo stp bridge-diameter Default The network diameter of the switched network is 7. Views System view Default command level 2: System level Parameters diameter: Specifies the switched network diameter in the range of 2 to 7. Usage guidelines An appropriate setting of hello time, forward delay, and max age can speed up network convergence.

Syntax stp mode { mstp | rstp | stp } undo stp mode Default A spanning tree device operates in MSTP mode. Views System view Default command level 2: System level Parameters mstp: Configures the spanning tree device to operate in MSTP mode. rstp: Configures the spanning tree device to operate in RSTP mode. stp: Configures the spanning tree device to operate in STP mode.
Default command level 2: System level Usage guidelines Configured in Ethernet interface view, the setting takes effect only on the interface. Configured in port group view, the setting takes effect on all member ports in the port group. Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface. Configured on a member port in an aggregation group, the setting takes effect only after the port leaves the aggregation group.
legacy: Configures the device to calculate the default path cost for ports based on a private standard. Usage guidelines If you change the standard that the device uses in calculating the default path costs, you restore the path costs to the default. Examples # Configure the device to calculate the default path cost for ports based on IEEE 802.1d-1998.
You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port that operates in full duplex mode. HP recommends that you use the default setting to let the device automatically detect the port link type. The stp point-to-point force-false or stp point-to-point force-true command configured on a port in MSTP mode is effective on all MSTIs.
Configured in port group view, the setting takes effect on all member ports in the port group. Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface. Configured on a member port in an aggregation group, the setting takes effect only after the port leaves the aggregation group. To set the priority of an MSTP port in a specific MSTI, use this command with the MSTI specified. Port priority affects the role of a port in a spanning tree.
all: Specifies all MSTIs. Examples # In MSTP mode, enable outputting port state transition information for MSTI 2.
Syntax stp region-configuration undo stp region-configuration Views System view Default command level 2: System level Usage guidelines These are the default settings for the MST region: • The MST region name of the device is the MAC address of the device. • All VLANs are mapped to the CIST. • The MSTP revision level is 0. After you enter MST region view, you can configure the MST region-related parameters, including the region name, VLAN-to-instance mappings, and revision level.
Examples # In MSTP mode, specify the device as the root bridge of MSTI 1. system-view [Sysname] stp instance 1 root primary Related commands • stp priority • stp root secondary stp root secondary Use stp root secondary to configure the device as a secondary root bridge. Use undo stp root to restore the default. Syntax stp [ instance instance-id ] root secondary undo stp [ instance instance-id ] root Default A device is not a secondary root bridge.
Syntax stp root-protection undo stp root-protection Default The root guard function is disabled. Views Ethernet interface view, port group view, Layer 2 aggregate interface view Default command level 2: System level Usage guidelines Configured in Ethernet interface view, the setting takes effect only on the interface. Configured in port group view, the setting takes effect on all member ports in the port group.
Views System view Default command level 2: System level Usage guidelines With the TC-BPDU guard function, you can set the maximum number of immediate forwarding address entry flushes that the device can perform every a certain period of time (10 seconds). For TC-BPDUs received in excess of the limit, the device performs a forwarding address entry flush when the time period expires. This prevents frequent flushing of forwarding address entries.
stp timer forward-delay Use stp timer forward-delay to set the forward delay timer of the device. Use undo stp timer forward-delay to restore the default. Syntax stp timer forward-delay time undo stp timer forward-delay Default The forward delay timer is 15 seconds. Views System view Default command level 2: System level Parameters time: Sets the forward delay (in 0.01 seconds). The value range is 400 to 3000 in increments of 100 (as indicated by 400, 500, 600).
Default The hello time is 2 seconds. Views System view Default command level 2: System level Parameters time: Sets the hello time (in 0.01 seconds). The value range is 100 to 1000 in increments of 100 (as indicated by 100, 200, 300). Usage guidelines Hello time is the time interval at which spanning tree devices send configuration BPDUs to maintain spanning tree.
Parameters time: Sets the max age (in 0.01 seconds). The value range is 600 to 4000 in increments of 100 (as indicated by 600, 700, 800). 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 yes, a new spanning tree calculation process starts. The max age timer takes effect only on the CIST. HP recommends not setting the max age timer with this command.
In a stable network, this kind of spanning tree calculation might occur because the upstream device is busy. You can avoid such unwanted spanning tree calculations by lengthening the timeout time (by setting the timeout factor to 4 or more), saving the network resources. HP recommends that you set the timeout factor to 5, 6, or 7, for a stable network. Examples # Set the timeout factor of the device to 7.

Use undo dot1q ethernet-type to restore the default. Syntax dot1q ethernet-type hex-value undo dot1q ethernet-type Default The TPID value for the outmost VLAN tag of VLAN-tagged packets received and sent by the interface is 0x8100.
Usage guidelines After you execute the dot1q ethernet-type command, only packets whose TPID in the outermost VLAN tag is 0x8100 or the value you configured will be processed as VLAN-tagged packets. When sending a packet, the interface sets the TPID value in the outermost VLAN tag to the configured value, and sets the TPID values in the other VLAN tags to 0x8100 if the packet carries two or more layers of VLAN tags.
