show port
To display port status and counters, use the show port command.
show port [mod[/port]]
Syntax Description
mod/port
|
(Optional) Number of the module and the port on the module.
|
Defaults
This command has no default settings.
Command Types
Switch command
Command Modes
Normal
Usage Guidelines
If you do not specify a mod, the ports on all modules are shown.
If you do not specify a port, all the ports on the module are shown.
In the Status field for the switch ports, the following applies:
•
connected indicates the port is operational.
Note
connected is also displayed for the status of a port that is receiving remote fault indications. Remote fault indications are not sent until the link comes up and both ends can hear each other. This means that the link is up and working correctly. According to the 802.3z Gigabit Ethernet Specification, a link partner is not allowed to send remote fault indications until after the link comes up successfully.
•
notconnect indicates the port is off or there is no GBIC in port.
•
faulty indicates the port failed diagnostics tests.
•
remfault indicates the far end station cannot synchronize with its receive signal.
•
disable indicates the port has been manually disabled.
•
remdisable indicates the far end port has been manually disabled.
•
configerr indicates that this port is not satisfied with the output of flow control and or duplex negotiation.
•
remcfgerr indicates that the far end port is not satisfied with the output of flow control and or duplex negotiation.
•
disagree indicates that the two ports have failed to agree on a duplex condition or that autonegotiation has failed.
In the show port command display, the combination of the 32-port module (WS-X4502) and 4-port 100FX card results in an entry that lists 36 ports. If the uplink card is not installed, only ports 1 through 32 are listed.
Although me1 resides on the supervisor engine module for the Catalyst 4000 family switches, me1 port information is not displayed by the show module or show port CLI commands.
