    Monitoring Load-Balanced Martini Circuits

    Purpose

    Display information about load-balanced Martini circuits

    Action

    To display brief information about load-balanced Martini circuits:

    host1#show mpls l2transport load-balancing-group member-circuits brief
    
    4 member ports:
          fastEthernet 2/0  down
          fastEthernet 3/0  30 member circuits
          fastEthernet 4/0  30 member circuits
          fastEthernet 5/0  30 member circuits
        90 member circuits

    To display detailed information about load-balanced Martini circuits:

    Note: For a simpler view, the show mpls l2transport interface command displays only the currently active VLAN or S-VLAN subinterface. Because load-balanced circuits are configured on subinterfaces on multiple ports, only one of which is active at a given time, this command does not give a complete picture of the configuration.

    Meaning

    Table 1 lists the show mpls l2transport load-balancing-group command output fields.

    Table 1: show mpls l2transport load-balancing-group Output Fields

    Field Name

    Field Description

    routed to/base LSP

    Identifies address of the router at the other end of the tunnel and the base tunnel that is selected to forward the traffic

    load-balancing group

    Group number

    Martini group-id

    Martini group ID number for the interface

    state

    State of the interface

    vc-id

    VC ID number for the interface

    mtu

    Maximum transmission unit for the inter

    In label

    Label sent to upstream neighbor for route; statistics below this field are the aggregate statistics for traffic from the core

    Out label

    Label received from downstream neighbor for route; statistics below this field are the aggregate statistics for traffic to the core

    pkts

    Number of packets sent across tunnel

    hcPkts

    Number of high-capacity (64-bit) packets sent across tunnel

    octets

    Number of octets sent across tunnel

    hcOctets

    Number of high-capacity (64-bit) octets sent across tunnel

    errors

    Number of packets dropped for some reason before being sent

    queue 0

    Number of the queue for which statistics are being displayed and whether the queue is under traffic class control

    traffic class

    Name of traffic class

    bound to

    Interface to which queue is bound

    Queue length

    Size of queue in length and bytes

    Forwarded

    Number of forwarded packets and bytes

    Dropped committed

    Number of committed packets and bytes dropped

    Dropped conformed

    Number of conformed packets and bytes dropped

    Dropped exceeded

    Number of exceeded packets and bytes dropped

    discardPkts

    Number of packets discarded due to lack of buffer space before being sent

    Member Interfaces

    Information about the member interfaces for the circuit

    Interface

    Interface specifier and status; active indicates it is being used for traffic from the core; if active is not displayed, interface is not currently being used for traffic, but the statistics may be valid

    member ports

    Number and type of candidate ports configured for the group, including interface specifiers and state

    member circuits

    Number of member circuits configured for each port and for the group
