show port

Use the show port command to display port status and counters.

Syntax Description

Default

This command has no default setting.

Supported Platforms

Catalyst 5000 family switches
Catalyst 4000 family switches
Catalyst 2926G series switches
Catalyst 2948G switch
Catalyst 2980G switch

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

In the status field for the Catalyst 5000 family, 4000 family, 2926G series, 2948G, and 2980G 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 everything is 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.

---

• notconnected 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.

For Catalyst 4000 family switches, in the show port command display, the combination of the 32-port module (WS-X4502) and 4-port 100FX daughtercard results in an entry that lists 36 ports. If the uplink daughtercard is not installed, only ports 1 through 32 are listed.

Although me1 resides on the supervisor engine module for the Catalyst 4000 family and 2948G switches, me1 port information is not displayed by the show module or show port CLI commands.

The Catalyst 2948G and 2980G switches are fixed configuration switches. Ports are located on module 2 for the 2948G and on modules 2 and 3 for the 2980G; for this reason, if you enter mod_num/port_num 1/N, an error message will be displayed.

Examples

This example shows how to display the status and counters for port 1 on module 3 (Catalyst 5000 family and 2926G series switches):

show port broadcast

Use the show port broadcast command to display broadcast information.

Syntax Description

Default

This command has no default setting.

Supported Platforms

Catalyst 5000 family switches
Catalyst 2926G series switches

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

On the 1000BaseX switching module, when you specify a port for broadcast suppression, the traffic is suppressed only in the network-to-Catalyst 5000 family and 2926G series switches bus direction.

If you do not specify a mod_num, the ports on all modules are shown.

If you do not specify a /port_num, all the ports on the module are shown.

Example

This example shows how to display broadcast information for port 2 on module 1:

Console> show port broadcast 1/2
Port     Broadcast-Limit Broadcast-Drop
-------- --------------- --------------
 1/2           75.25%           -
Console> 

Table 2-46 describes the possible fields in the show port broadcast command output.

Table 2-46: show port broadcast Command Output Fields

Field	Description
Port	Module and port number.
Broadcast-Limit	Broadcast threshold configured for the port in percent or packets per second.
Broadcast-Drop	Number of broadcast/multicast packets dropped because the broadcast limit for the port was exceeded.

show port capabilities

Use the show port capabilities command to display the capabilities of the modules and ports in a switch.

Syntax Description

Default

This command has no default setting.

Supported Platforms

Catalyst 5000 family switches
Catalyst 4000 family switches
Catalyst 2926G series switches
Catalyst 2948G switch
Catalyst 2980G switch

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

If you do not specify a mod_num, the ports on all modules are shown.

If you do not specify a /port_num, all the ports on the module are shown.

The Catalyst 2948G and 2980G switches are fixed configuration switches. Ports are located on module 2 for the 2948G and on modules 2 and 3 for the 2980G; for this reason, if you enter mod_num/port_num 1/N, an error message will be displayed.

Example

This example shows how to show the port capabilities for module 1, port 1:
