Verify BMC switch functionality
After updating the BMC switch, ensure that the switch is fully functional, based on the solution configuration.
In addition to comparing the running configuration of the switch to the backup configuration file saved before updating the switch firmware, these suggested validation procedures help to verify that:
Switch NOS is updated and set to boot to it
All links are up and IP addresses are assigned
BGP connections are up and sessions are established
ACLs are in place and counters are incrementing
Perform each of the following tasks to ensure that the updated BMC switch is working properly before proceeding.
Verify BMC switch update
To verify that the switch NOS update has been applied and the switch is set to boot to the updated image, sign in to the BMC switch and run the following command:
| show boot |
| Example |
|---|
|
Verify links
To verify that all links are up and IP addresses are assigned, run the following command:
| show interface link state up |
| Example |
|---|
|
Note
The state of ports 1 through 16 depends on the number of nodes in the solution. The above example is from a 4-node solution.
Another useful command to verify IP configuration and state:
| show interface ip |
| Example |
|---|
|
Verify BGP is operational
To verify that the BGP connections are up and sessions are established, run the following command:
| show ip bgp neighbor summary |
| Example |
|---|
|
Verify ACLs are present and operational
To verify that ACLs are in place and counters are incrementing, run the following command:
|
| Example |
|---|
|
| Example |
|---|
|
| Example |

Verify solution network connectivity
Once the basic system convergence is verified in the updated BMC switch, test connectivity for the following:
Ping from BMC switch to connected TOR switch IP interfaces
