# 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 99 lists the show mpls l2transport load-balancing-group command output fields.

Table 99: 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
