How to enable redundant Supervisor Engine in Cisco Nexus 7000 Series Switch?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Recently I was upgrading our Cisco Nexus 7010 Switch NX-OS version from 5.0 (3) to 6.1 (4). After the upgrade process when I used the NX-OS command “show system redundancy status” to check the high availability of Nexus Supervisor module-1X Engines I discovered one of them was just power up but not under operation in Standby mode.

In order to bring up the Nexus Supervisor module-1X into standby mode, I used the NX-OS command “attach module slot no” in my case the slot no was 5. So I used the NX-OS Command “attach module 5”

Nexus Module2

Upon issuing the “attach module 5” I ran again the NX-OS command “show system redundancy status” to check the HA between Nexus Supervisor module-1X Engines and discovered that the redundancy state was in standby mode and the Internal State was under synchronization process.

Once I got message in console “Connectivity Management processor (on module 5) is now UP”

Again I checked the system redundancy state and discovered module 5 was in standby mode.

In upcoming posts I will discuss the challenges I faced to upgrade Nexus 7010 Switch NX-OS version from 5.0 (3) to 6.1 (4).
