show spx ring

Displays information on port extender (PE) rings or chains in a Switch Port Extender (SPX) system.
Syntax
show spx ring { all | ID | chain unit/slot/port }
Parameters
all
Displays information for all PE rings in the Campus Fabric domain.
ID
Specifies the ID of the PE ring, in decimal format, for which information is displayed.
chain
Displays information on PE chains in the Campus Fabric domain.
unit/slot/port
Specifies the connecting port that identifies the PE chain.
Modes

All modes

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

The following example shows output for all PE chains in the domain.

device# show spx ring chain

             PE29   57      ACTIVE      29/1/1      29/2/3    YES       PE24    x--x

             -----------------------------------------------------------------------------

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.
