Replacing Supervisor 2 Modules With Supervisor 2E Modules - Cisco Nexus 7000 Hardware Installation And Reference Manual

Chapter 10 Installing or Replacing Components
While the configuration is applied on the Supervisor 2 or Supervisor 2E module you will see an error
Note
that indicates a problem with the cmp-mgmt interface or AUX port. The Supervisor 2 and Supervisor 2E
modules do not have the CMP utility nor the AUX port, so you can disregard this error message.
switch(config)# interface cmp-mgmt module 5
Invalid interface format at '^' marker.
...
switch(config)# line com1
% Invalid command at '^' marker.
If the imported configuration file includes configurations for Fabric Extenders (FEXs) and those
Note
modules are not up yet, you will see error messages for that. If that happens, we recommend that you
run the FEX configuration again after the FEX modules come online. You can verify the status of the
FEX modules and for the associated server-facing interfaces by using the show fex and show interface
brief commands.
If you have not inserted the standby supervisor module until now, do not insert it during this step.
Note
Instead, wait until you complete this procedure before installing the standby supervisor module.
Save the configuration in the startup configuration by using the copy running-config startup-config
Step 21
vdc-all command.
switch(config)# copy running-config startup-config vdc-all

Replacing Supervisor 2 Modules with Supervisor 2E Modules

Before migrating from Supervisor 2 modules to Supervisor 2E modules, note the following guidelines:
•
•
To migrate from using Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, follow these
steps:
Replace one of the Supervisor 2 modules by following the steps in the
Step 1
Supervisor Module During System Operations" section on page
Verify that the Supervisor 2E module has 2 CPUs and 32 GB of DRAM by looking at the bootup output
Step 2
(see the highlighted portions in the following example).
CPU - 2 : Cores - 4 : HTEn - 1 : HT - 2 : Features - 0xbfebfbff

This migration process is not disruptive for switches with redundant (two) supervisors but it is
disruptive for switches that have only one supervisor module.
Non disruptive backward migration (migrating from Supervisor 2E modules to Supervisor 2
modules during switch operations) is not supported—in a switch with two supervisor modules and
an active Supervisor 2E module, a Supervisor 2 will not boot up nor synchronize with the active
Supervisor 2E module.
