pe-id

Assigns and reserves an ID for an SPX port extender (PE) unit.
Syntax
pe-id port unit-id [ port | name ]
no pe-id port unit-id [ port | name ]
pe-id name unit-id1 [ unit-id2 unit-id3 unit-id4 ] [ port | name ]
no pe-id name unit-id1 [ unit-id2 unit-id3 unit-id4 ] [ port | name ]
Command Default

By default, the system generates the PE IDs for attached PE units.

Parameters
port
In the form unit/slot/port, designates the CB SPX port or a port in the CB SPX LAG that links to the PE unit-id.
name
The PE group name for an SPX port or SPX LAG that is associated with the ID or IDs that follow. Up to four IDs may be associated with the PE group name. The PE group name must also be defined in CB configuration mode.
unit-id
Designates the PE ID or IDs associated with the port or the PE group name. PE ID values range from 17 through 56.
Modes

CB configuration mode

Usage Guidelines

The no form of the command removes the PE ID and any associated configuration.

The second set of [ port | name ] parameters after the unit-ids provides an option to specify a ring topology. (Although a ring topology is not supported in FastIron 8.0.40, the configuration is allowed for compatibility with future releases.)

The output of the show running-config command shows the merged result of system-generated PE IDs and the user's reserved PE ID configuration. The system overwrites user entries if there is a conflict.

If a reserved stack unit is removed, its associated SPX port configuration and PE ID configuration are removed.

Users are allowed to change the PE ID configuration of live PE units as long as the new configuration does not alter the topology of the live units.

Examples

The following example assigns the PE ID 20 to the first PE that attaches to SPX port 2/1/15. The next PE unit that links to PE unit 20 is assigned PE ID 22. 

device# configure terminal
device(config)# spx cb-configure
device(config-spx-cb)# spx-port 2/1/15 pe-group bld1-f13-stk2
device(config-spx-cb)# pe-id bld1-f13-stk2 20 22

The PE group name or any port in a LAG can be used to reserve the PE ID. The following three examples configure the same PE ID, assuming both ports 1/1/10 and 1/1/11 are in the same SPX LAG and have the PE group name shown. 

device(config)# pe-id 1/1/10 20

device(config)# pe-id 1/1/11 20

device(config)# pe-id bld1-fl3-stk7 20
