Managing PEs

Once the Campus Fabric domain is deployed, you may want to optimize PEs in various ways. Zero-touch deployment provides two options for managing PE IDs.

Changing PE IDs

Previously, changing PE IDs required powering down the units and changing the PE ID configuration.

With option 1 of SPX interactive-setup, you can change PE IDs without shutting down the PEs or changing any connections or topology. Refer to Deployment Scenario 6: Changing PE IDs Using SPX Interactive-Setup.

Changing PE IDs

Recommendations for PE ID Changes

• PE ID changes are allowed when IDs are not already used in the topology.

• If any IDs are in the reserved configuration, they are not available for use when PE IDs are changed.

• Swapping PE IDs is not allowed.

• PE ID changes do not require any change to the topology or to existing connections.

Customers may want to move PEs to other CB or PE SPX ports or SPX LAGs and still use the same PE IDs. SPX PE movement requires the spx allow-pe-movement option to be enabled in global configuration.

SPX# configure terminal
SPX(config)# spx allow-pe-movement
Please remove the spx allow-pe-movement configuration after the PEs are moved.

Moving PEs

Move PEs by changing connections or topology but retaining the old PE ID: This is achieved with the spx allow-pe-movement command. Refer to Deployment Scenario 7: SPX PE Movement: Moving PEs Without Changing IDs.
