Displaying VPLS information

Total VPLS peers The number of VPLS peers this device has for this VPLS instance, as well as the number of

these VPLS peers with which this device has an LDP session.

Peer address The IP address of the VPLS peer.

State The current state of the connection with the VPLS peer. This can be one of the following states:

• Operational – The VPLS instance is operational. Packets can flow between the device and

the peer

• Wait for functional local ports – The physical endpoint port that must be connected to the

Customer Edge device is down due to a link outage or is administratively disabled

• Wait for LSP tunnel to Peer – The device cannot find a working tunnel LSP

• Wait for PW Up (Wait for LDP session to Peer)– The LDP session is not yet ready

• Wait for PW Up (Wait for remote VC label) - The device has advertised its VC label binding

to the VPLS peer, but has not yet received the peer’s VC label binding

• Wait for PW Up (VC type mismatched) – A session is not formed because the VC type does

not match with its peer's VC type

• Wait for PW Up (MTU mismatched) – The MTU sent to a peer is derived from the device's

global setting by the following formula: (system-mtu minus 26 bytes). When a system-mtu

value is not configured, a default value of 1500 is sent.

• Wait for PW Up (Wait for LPD session to Peer) - The LDP session to the peer is down

• Wait for PW Up (No Label Resource) - When configuring a new VPLS peer, the maximum

amount of VC labels that can be supported may exceed 64K, and cause the configuration

to be rejected. The maximum amount of VC labels available for VPLS instances is equal to

64K.

Uptime The time in minutes that the entry has been operational.

Tnnl in use The tunnel LSP used to reach the VPLS peer.

When VPLS traffic to the peer is load balanced across multiple tunnel LSPs, the tunnel LSPs

used to reach the peer are displayed.

LDP session The state of the LDP session between this device and the VPLS peer.

Local VC lbl The VC label value locally allocated for this peer for this VPLS instance. Packets forwarded

from the VPLS peer to this device are expected to contain this label.

This is the label that is advertised to the VPLS peer through LDP.

Remote VC lbl The VC label allocated by the VPLS peer and advertised to this device through LDP.

The device applies this label to outbound MPLS packets sent to the VPLS peer.

Local VC MTU The MTU value locally configured for this peer.

Remote VC MTU The MTU value configured for the remote VPLS peer.

Local VC-Type The VC type for this peer.

Remote VC-Type The VC type for the remote VPLS peer.

CPU-Protection Whether CPU protection configured on this VPLS instance is ON or OFF.

On Brocade NetIron XMR and Brocade MLX series

devices only: When CPU protection is enabled on this VPLS instance but is temporarily

unavailable due to 100% multicast FID usage, this field includes the message shown above.

Local Switching Whether local switching behavior on a per-VPLS basis is enabled or disabled.

Extended Counter Indicates whether or not the extended counter is enabled for the configured VPLS.

Multicast

Snooping

Indicates whether the multicast snooping is enabled or disabled.
