show port

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

Syntax Description

mod	(Optional) Number of the module.
/port	(Optional) Number of the port on the module.

Defaults

This command has no default settings.

Command Types

Switch command.

Usage Guidelines

In the status field, the following applies:

•connected indicates the port is operational. 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.

•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.

Table 2-50 describes the possible fields (depending on the type of port queried) and the values in the show port capabilities command output.

Table 2-50 show port capabilities Command Output Fields

Field	Description
Model	Module model number.
Port	Module number and port number.
Type1	Port type, for example, 100BASE-FX MM, 100BASE-FX SM, or 10/100BASE-TX.
Speed1	Port speed setting (for example, auto, 100, or 1000).
Duplex	Duplex mode (half, full, auto, fdx, hdx, or no).
Trunk encap type	Trunk encapsulation type (ISL, 802.1Q, 802.10, or no).
Trunk mode	Trunk administrative status of the port (on, off, auto, desirable, nonegotiate, or no).
Channel	Status of which ports can form a channel group. The ports are shown in mod/port format. For example, 3/1-2 indicates module 3, ports 1 and 2. Also, any ports in range [mod/1-mod/high_port] or no ports may be indicated.
Broadcast suppression	Number of packets-per-second (pps) of broadcast/multicast traffic allowed on the port (0-150000) or the percentage of total available bandwidth that can be used by broadcast/multicast traffic (0-100).
Flow control	Flow-control options you can set (receive-[off, on, desired], send-[off, on, desired], or no).
Security	Status of whether port security is enabled (yes, no).
Membership	Method of membership assignment of a port or range of ports to a VLAN (static, dynamic).
Fast Start	Status of whether the spanning-tree port fast-start feature on the port is enabled (yes, no).
QoS Scheduling	(rx-(none),tx-(none)).
CoS Rewrite	Status of whether the port supports CoS rewrite (yes, no).
ToS Rewrite	Status of whether the port supports TOS rewrite (IP-Precedence).
Rewrite	Status of whether the port supports inline rewrite (yes, no).
