Replacing a Cisco Nexus 5000 Series Switch
When a Cisco Nexus 5000 Series switch has been replaced, perform the following configuration steps on the
replacement switch to synchronize it with the existing Cisco Nexus 5000 Series switch. The procedure can
be done in a hybrid Fabric Extender A/A topology and Fabric Extender Straight-Through topology.
1 Do not connect any peer-link, vPC, A/A or Straight-Through topology fabric ports to the replacement
switch.
2 Boot the replacement switch. The switch comes up with no configuration.
3 Enable pre-provisioning on all Fabric Extender A/A and ST modules.
4 Configure the replacement switch:
If the running-configuration was saved offline, follow steps 5-9 to apply the configuration.
If the running-configuration was not saved offline, you can obtain it from the peer switch if the configuration
synchronization feature is enabled. (See Steps 1 and 2 from "Creating a Switch Profile on a Local and
Peer Switch" then begin with step 10 below).
If neither condition is met, manually add the configuration and then begin with step 10 below.
5 Edit the configuration file to remove the sync-peer command if using the configuration synchronization
feature.
6 Configure the mgmt port IP address and download the configuration file.
7 Copy the saved configuration file to the running configuration.
8 Verify the configuration is correct by entering the show running-config command and the show provision
failed-config slot command.
9 If switch-profile configuration changes were made on the peer switch while the replacement switch was
out-of-service, apply those configurations in the switch-profile and then enter the commit command.
10 Shutdown all Fabric Extender ST topology ports that are included in a vPC topology.
11 Connect the Fabric Extender ST topology fabric ports.
12 Wait for Fabric Extender ST topology switches to come online.
13 Ensure the vPC role priority of the existing switch is better than the replacement switch.
14 Connect the peer-link ports to the peer switch.
15 Connect the Fabric Extender A/A topology fabric ports.
16 Connect the switch vPC ports.
