3Com Switch 8800 Family Configuration Guide

VPLS Basic Configuration 641
By default, VC-ID is as big as VSI-ID.
Specifying the VC encapsulation type of the VSI
Perform the following configuration in VSI view.
By default, the VC encapsulation type in the VSI takes this value.
Configuring VLAN for
User Access and Binding
a VLPS Instance
The port configuration on a VLAN interface differs depending on user access
modes. If user gets access by Ethernet, you must enable VLAN-VPN on the access
port of the VLAN. If user makes H-VPLS access by VLAN, or user’s convergence
multi-tenant unit (MTU) makes H-VPLS access by VLAN-VPN, you need not enable
VLAN-VPN on the access port; instead, you must configure the port as Trunk, in
this case, the VLAN Tag (VLAN ID currently configured for the user) carried in
uplink packets must be consistent with that of the VLAN bound with the Trunk. If
convergence UPE makes H-VPLS access by LSP, you can bind a VPLS instance to a
VLAN containing no port. Additionally, you cannot bind one instance to multiple
VLANs.
Perform the following configuration in VLAN interface view.
c
CAUTION:
■ If any of GVRP, STP and 802.1x protocols is enabled on a port, you cannot
enable VLAN VPN on the port;
■ If IGMP Snooping is enabled in the VLAN to which the port belongs or if IGMP
is enabled on the VLAN interface to which the port belongs, it is not allowed to
enable VLAN VPN on the port, and vice versa;
■ If a port with enabled VLAN VPN is to join in a VLAN, IGMP Snooping cannot
be enabled on the VLAN and IGMP cannot be enabled on its VLAN interfaces;
■ The interface of a VLAN with a VPLS instance bound to it cannot be assigned
an IP address. Similarly, if the interface of a VLAN is assigned an IP address, you
cannot bind VPLS instances to it.
