wtr-time wtr-time: Specifies the switchback delay time, or the wait-to-restore time. After the primary PW comes back, the system waits for a period of time dictated by the switchback delay time before switching data from the secondary PW back to the primary PW. The wtr-time argument is in the range of 1 to 720, in minutes. The default is 30 minutes. Use dual-npe revertive to enable the switchback function and set the switchback delay time. Use undo dual-npe revertive wtr-time to restore the default switchback delay time. Use undo dual-npe revertive to disable the switchback function. By default, the switchback function is disabled. # Create a VPLS instance named vpna that uses the peer discovery mechanism of manual configuration and set the switchback delay time to 1 minute.

VLAN ID is in the range of 1 to 4094. only-tagged: Matches only tagged packets. If the specified VLAN ID is the default VLAN of the port and the only-tagged keyword is not specified, the service instance matches untagged packets as well as packets carrying the current port's default VLAN ID. port-based: Matches packets by port. tagged: Matches tagged packets. untagged: Matches untagged packets. Use encapsulation to configure a packet matching rule for the current service instance. Use undo encapsulation to remove the packet matching rule of the current service instance. 25

By default, no packet matching rule is configured for a service instance. If you configure this command for a service instance for multiple times, only the last configuration will take effect. On a port, if you have configured a rule to match packets carrying the port's PVID tag in a service instance without specifying the only-tagged keyword, and to match untagged packets in another service instance, untagged packets will be matched in the service instance where this command was configured first. H3C recommends that you also specify the only-tagged keyword to match packets carrying specific VLAN tags. Otherwise, untagged packets might be matched to a different service instance than the one you expected. Specify different VLAN IDs for different service instances on the same Layer 2 Ethernet interface. # Configure service instance 100 to match VLAN 100.

l2 binding vsi l2 binding vsi vsi-name [ access-mode { ethernet vlan } { hub spoke } ] * undo l2 binding vsi vsi-name Interface view vsi-name: Name of the VPLS instance, a case-insensitive string of 1 to 31 characters. Hyphens (-) are not allowed. access-mode: Specifies the access mode of the VPLS instance, which can be ethernet or vlan. When the interface bound with the VPLS instance is a routing interface, the default access mode is Ethernet. When interface bound with the VPLS instance is a routing subinterface, the default access mode is VLAN. ethernet: Specifies the access mode of Ethernet. vlan: Specifies the access mode of VLAN. hub: Specifies that the attached CE is the hub-ce. spoke: Specifies that the attached CE is a spoke-ce. This is the default when the hub-spoke feature is enabled for the instance. Use l2 binding vsi to bind a VPLS instance on an interface. Use undo l2 binding vsi to remove the binding. When the hub-spoke feature is enabled for a VPLS instance (the hub-spoke keyword included in the vsi static command), you can also specify whether the attached CE is a spoke site or the hub site. IMPORTANT: With the l2 binding vsi command configured on an interface, services bound to the interface are considered the internal VPN services of the VPLS instance. After a Layer 3 interface is bound with a VPLS instance, its Layer 3 subinterfaces cannot be bound with an L2VPN or VPLS instance. After a Layer 3 subinterface is bound with a VPLS instance, the corresponding Layer 3 interface cannot be bound with an L2VPN or VPLS instance.

mac-learning mac-learning { enable disable } VSI view enable: Enables MAC address learning for the VPLS instance. disable: Disables MAC address learning for the VPLS instance. Use mac-learning to enable or disable MAC address learning for a VPLS instance. With MAC address learning disabled for a VPLS instance, the system does not learn source MAC addresses from the packets received from the VPLS instance. By default, MAC address learning is enabled. # Enables MAC address learning for VPLS instance aaa. [Sysname] vsi aaa [Sysname-vsi-aaa] mac-learning enable mac-table limit VSI view mac-table limit mac-limit-number undo mac-table limit mac-limit-number: Maximum number of MAC addresses that the switch can learn for the VPLS instance.

Use mac-table limit to specify the maximum number of MAC addresses that the switch can learn for the VPLS instance. Use undo mac-table limit to restore the default. 28

By default, the maximum number depends on the system working mode. For more information, see Fundamentals Configuration Guide. Once the number of MAC addresses learned for a VPLS instance reaches this limit, the switch does not learn source MAC addresses any more but broadcasts the received packet in the VPLS instance. # Set the maximum number of MAC addresses that the switch can learn for VPLS instance aaa to 1024.

Use undo mac-withdraw null-ip-address-tlv to configure the signaling protocol to not carry an empty IP address list TLV in MAC address withdraw messages. By default, a MAC address withdraw message carries an empty IP address list TLV. Use the mac-withdraw null-ip-address-tlv command or its undo form on your device to make sure the two end devices of a PW have the same implementation on whether a MAC address withdraw message will carry an empty IP address list TLV. Otherwise, when a primary/backup PW switchover occurs, the local device cannot receive the MAC address withdraw message from the peer device. For more information about the Address List TLV, see "Address Withdraw Message" in RFC 5036. # Configure the signaling protocol to not carry an empty IP address list TLV in MAC address withdraw messages.

mtu (VSI view) mtu mtu undo mtu VSI view mtu: Maximum transmission unit (MTU) for the VPLS instance, in the range of 328 to 8192. The default is 1500. Use mtu to set the MTU of a VPLS instance. Use undo mtu to restore the default. The MTU of a VPLS instance is a global attribute and is also the MTU of the PW. In Martini VPLS, the MTUs of VPLS instances of peer PEs must be identical. In Kompella VPLS, the MTUs of VPLS instances of peer PEs can be different. # Set the MTU of VPLS instance aaa to 1400.

The default is VSI ID. upe: Specifies that the peer PE is a UPE in the H-VPLS model. backup-peer ip-address: Specifies the IP address of the backup NPE. If you specify this parameter, you create a primary NPE and a backup NPE on the UPE. backup-pw-id pw-id: Specifies the ID of the PW to the backup NPE. The pw-id argument is in the range of 1 to 4294967295, and the default is the VSI ID. Use peer to create a peer PE for a VPLS instance. Use undo peer to remove a peer PE. With the hub-spoke feature for a VPLS instance, you can specify the connection mode of the peer PE as hub or spoke.
