Deployment Scenario 6: Changing PE IDs Using SPX Interactive-Setup

Use the SPX interactive-setup utility to make changing PE IDs simpler.

Reference Topology: Changing PE IDs with SPX Interactive-Setup

PE ID Change Considerations

  • The new PE ID can be assigned only if the ID is not taken and if no reserve configuration is associated with the ID.

  • The PE IDs cannot be changed or swapped on PE units that are physically present in the Campus Fabric domain.

  • Ruckus recommends that you change PE IDs, if desired, when the Campus Fabric is initialized and before connecting hosts or configuring protocols.

Attention: Proceed with caution when changing PE IDs. Only the SPX LAG and SPX port configuration is dynamically changed after a PE ID change. Once PE IDs are changed, the user is responsible for reconfiguring all the configurations applicable to the old PE ID ports.

In the following example, PE 17 becomes PE 24, and PE 18 becomes PE 23.

  1. Use the show running-config command to verify the domain and the PE ID configuration. 
    ICX7750-48F Router(config)# show running-config
Current configuration:

  2. Run the SPX interactive-setup utility, and choose option 1 to change PE IDs. When prompted, enter the desired PE IDs and confirm your changes. 
    ICX7750-48F Router# spx interactive-setup
You can abort spx interactive-setup at any stage by <ctrl-c>
0: quit
1: change PE IDs
2: discover and convert new units (no startup-config flash) to PEs
3: discover and convert existing/new standalone units to PEs
The example shows the options available when you start the interactive-setup utility.
4. When prompted, type "1" to change PE IDs.
Please type your selection: 1
           +----+ 	      +----+
 1/1/3--2/3| 18 |2/5==2/5| 17 |2/4--1/1/16
 	    +----+         +----+
You can type n to cancel. If you need to cancel later, type Cntrl-C at any time.
Type "done" to finish, or a new ID for PE 18 (default 18): 23
Type "done" to finish, or a new ID for PE 17 (default 17): 24
Change IDs: 18->23, 17->24,
Do you want to proceed? (enter 'y' or 'n'): y

    Note: Be sure that the zero-touch utility is disabled before running the SPX interactive-setup utility. 

    ICX7750-48F Router(config-spx-cb)# no zero-touch-enable 
ICX7750-48F Router(config-spx-cb)# end
In the example, the zero-touch utility is disabled as a precursor to enabling interactive-setup.
  3. The affected PEs are assigned new PE IDs and rejoin the network with the new IDs. 
    T=14m43.4: Sending new IDs to PE(s) 17-18...
power down ports to detach PEs: 1/1/3 1/1/16
power up ports: 1/1/3 1/1/16.
Affected PEs will join with new IDs.
Exit spx interactive-setup, reason: done ID changes
Sica Unit id:24, PoD License Capacity:8
Stack unit 24 Power supply 1 is up
Stack unit 24 Power supply 2 is down
Sica Unit id:23, PoD License Capacity:8
Stack unit 23 Power supply 1 is up
Stack unit 23 Power supply 2 is down
  4. Use the show spx command to verify the topology and the operational state of the PEs. Then enter the write memory command to save the configuration. 
    SPX# show spx
T=17m13.2: alone: standalone, D: dynamic cfg, S: static
ID Type Role Mac Address Pri State Comment
1 S ICX7750-48XGF alone cc4e.24d2.2c00 0 local Ready
23 D ICX7250-24 spx-pe cc4e.24dc.e9ce N/A remote Ready
24 D ICX7250-24 spx-pe cc4e.24dc.f166 N/A remote Ready

    +---+
 2/1| 1 |2/4
    +---+
 	     +----+       +----+
 1/1/3--2/3| 23 |2/5==2/5| 24 |2/4--1/1/16
           +----+        +----+

The example changes the ID for PE 18 to 23 and the ID for PE 17 to 24
ICX7750-48F Router# write memory
  5. Use the show spx csp all or show debug all command to verify the CSP operational status and any other items as needed. If the topology includes a PE ring, use the show spx ring all command to verify that the ring is in the active state.

    Note: There are no specific show commands for ZTP. All commands that apply to SPX also apply to ZTP. Refer to Debugging and Verification Commands.
