(SPX) system.

Examples
The following example displays information for all PE rings in a Campus Fabric domain.
device# show spx ring all ------------------------------------------------------------------------------------ Ring Id |FSM State |CB port Lag |Remote CB port Lag |Log Block Link ------------------------------------------------------------------------------------ 1 ACTIVE 1/1/2 3072 1/1/3 3073 PE29x--xCB1/1/3 2 ACTIVE 3/1/19 3076 3/1/45 3078 CB3/1/19x--xPE26 3 ACTIVE 2/1/12 3075 3/1/31 3077 PE27x--xPE28 4 ACTIVE 1/1/5 3079 2/1/9 3074 PE19x--xPE20
The following example narrows the output to a specific ring (ring IDs can be derived
from the
show spx ring all command).
device# show spx ring 1 ------------------------------------------------------------------------------------- Ring Id |FSM State |CB port Lag |Remote CB port Lag |Log Block Link ------------------------------------------------------------------------------------- 1 ACTIVE 1/1/2 3072 1/1/3 3073 PE29x--xCB1/1/3
The following example shows output for all PE chains in the domain.

The following example narrows the output to a PE chain from one CB port (port number can be the local CB unit or a remote CB unit).
device# show spx ring chain 1/1/2 <-- This port number can be a local CB Port or a remote CB port.
