4.1. Verify Physical Layer Connectivity
Verify that there is valid link light along the entire data path between the devices that can not switch to each
other. Make sure to include all inter-switch links. Verify LEDs on all involved CMMs and NIs are solid OK1,
blinking OK2 for OS10K or Solid OK for OS6900.
Use the show interfaces command to verify that operational status is up, speed and duplex are correct and
match the device on the other side of the connection.

If the port reports operational status down, verify the physical link, but also verify the necessary NIs and CMM
are receiving power and are up and operational. Use the show chassis command and the show cmm command
to verify this.
4.2. Verify Current Running Configuration
If the physical layer is validated, the next step is to verify the configuration. Use the show configuration
snapshot all command to display the current running configuration. Use this command to verify the ports
involved are in thecorrect VLAN. Also review the output of the command to verify there is nothing explicit in
the configuration that would cause the problem, such as a deny ACL that could be found under the QoS
subsection.
