Brocade(config-mpls-vpls-test)# cpu-protection
Error - Cannot configure CPU protection for VPLS 10 as multiple end-points
share the same physical port.
The restrictions exist because packets are hardware-forwarded when CPU protection is
enabled. In this case, source port suppression cannot be properly performed when there are
multiple endpoints on the same physical interface.
Specifying an untagged endpoint
To specify an untagged endpoint for a VPLS instance, enter commands such as the following.
Brocade(config-mpls)# vpls v1 40000
Brocade(config-mpls-vpls-v1)# vlan 100
Brocade(config-mpls-vpls-v1-vlan-100)# untagged ethernet 2/1
Syntax: [no] untagged [ethernet] portnum
NOTE
Foundry Discovery Protocol (FDP) must not be enabled on an untagged VPLS or VLL endpoint.
Specifying a single-tagged endpoint
Tagged ports are configured under a VLAN ID. A VPLS instance can have multiple ports configured
under the same VLAN ID, and can have ports configured under different VLAN IDs. Another VPLS
instance can reuse the same VLAN ID on other physical ports. Because the VLANs are configured
under different VPLS instances, they are different VPLS VLANs even though they use the same
VLAN ID.
To specify a tagged endpoint for a VPLS instance, enter commands such as the following:
Brocade(config-mpls)# vpls v1 40000
Brocade(config-mpls-vpls-v1)# vlan 200
Brocade(config-mpls-vpls-v1-vlan-200)# tagged ethernet 3/11
Syntax: vlan num
Syntax: [no] tagged ethernet slot/port
Specifying a dual-tagged endpoint
Dual-tagged ports are configured with two VLAN IDs. A VPLS instance can have multiple ports
configured under the same dual-tagged VLAN ID, and can have ports configured under different
VLAN IDs. Another VPLS instance can reuse the same VLAN ID on other physical ports. Because the
VLANs are configured under different VPLS instances, they are different VPLS VLANs even though
they use the same VLAN ID.
NOTE
Before configuring a dual-tagged endpoint, see “Special considerations for dual-tagged endpoints” .
To specify a dual-tagged endpoint for a VPLS instance, use the following commands.
