Logically Disabling GBIC and SFP Ports (CR00009993)
With this Software Version, you can disable optical GBIC and SFP ports either electrically or logically. Electrically disabling a port has the same effect as
physically removing the GBIC or SFP. Logically disabling a port takes the link down in software. The following table further describes the differences.
To display the port’s state, use the command show switch port=port-number as shown in Figure 2 , Figure 3 and Figure 4 . Check:
■ Status to see whether the port is ENABLED or DISABLED in software
■ Link State to see whether the link is up and the optics are turned on
Figure 2: Output of the show switch port command when the port is enabled
