Quidway S8500 Series Routing Switches
Use the undo l2 binding vsi command to remove the binding relation between a
VLAN and a VSI.
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.
Related command: vsi, peer.
Example
# Bind the VPLS instance Huawei to VLAN 100 in VLAN view. Enabled VLAN VPN on
the port of the VLAN indicates the VSI can be accessed through Ethernet.
[Quidway] interface GigabitEthernet3/1/4
[Quidway-GigabitEthernet3/1/4] vlan-vpn enable
[Quidway-GigabitEthernet3/1/4] port access vlan 100

[Quidway-Vlan-interface100] undo ip address
[Quidway-Vlan-interface100] L2 binding vsi Huawei
Caution:
If you have enabled GVRP, STP or 802.1x protocol for a port, you are prohibited
from enabling VLAN VPN feature for the port.
If you have enabled IGMP Snooping or IGMP for the VLAN which the port belongs
to, you are prohibited to enable VLAN VPN feature for the port. Similarly, if you have
enabled VLAN VPN feature for the port, you are prohibited from enabling IGMP
Snooping or IGMP for the VLAN which the port belongs to.
IF you want to add the ports with VLAN VPN enabled to a VLAN, you cannot enable
IGMP Snooping in the VLAN and enable IGMP for the VLAN interface.
You cannot configure an IP address for a VLAN interface with VPLS instances
bound to it. Similarly, you cannot bind a VPLS instance to a VLAN interface with an
IP address configured.
You can bind one VPLS instance to up to eight VLANs.
