show port

To display port status information, use the show port command.

show port [mod[/port]]

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.

Command Modes

Normal.

Usage Guidelines

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

If you do not specify a port value, all the ports on the module are shown.

The output for an 8-port T1/E1 PSTN interface module configured for transcoding or conferencing displays a transcoding port type as "mtp" (media termination point) or a conference port type as "conf bridge."

The output for an 8-port T1/E1 PSTN interface module displays a transcoding port type as "transcoding" or a conference port type as "conferencing."

The PAgP channel protocol and the LACP channel protocol manage channels differently. When all the ports in a channel get disabled, PAgP removes them from its internal channels list; show commands do not display the channel. With LACP, when all the ports in a channel get disabled, LACP does not remove the channel; show commands continue to display the channel even though all its ports are down. To determine if a channel is actively sending and receiving traffic with LACP, use the show port command to see if the link is up or down.

LACP does not support half-duplex links. If a port is in active/passive mode and becomes half duplex, the port is suspended (and a syslog message is generated). The port is shown as "connected" using the show port command and as "not connected" using the show spantree command. This discrepancy is because the port is physically connected but never joined spanning tree. To get the port to join spanning tree, either set the duplex to full or set the channel mode to off for that port.

For more information about PAgP and LACP, refer to the "Configuring EtherChannel" chapter of the Catalyst 6500 Series Switch Software Configuration Guide.

Table 2-60 describes the possible fields (depending on the port type queried) in the show port command output.

Table 2-60 show port Command Output Fields 

Field
Description

Port

Module and port number.

Name

Name (if configured) of the port.

Status

Status of the port (connected, notconnect, connecting, standby, faulty, inactive, shutdown, disabled, monitor, active, dot1p, untagged, inactive, or onhook).

Vlan

VLANs to which the port belongs.

Auxiliaryvlan1

Auxiliary VLANs to which the port belongs.

Duplex

Duplex setting for the port (auto, full, half).

Speed

Speed setting for the port (auto, 10, 100, 1000).

Type2

Port type (for example, 1000BASE-SX or 100BASE-FX, or T1, E1, transcoding, conferencing, mtp, or conf bridge for voice ports).

Security

Status of whether port security is enabled or disabled.

Secure-Src-Addr

Secure MAC address for the security-enabled port.

Last-Src-Addr

Source MAC address of the last packet received by the port.

Broadcast-Limit

Broadcast threshold configured for the port.

Multicast

Number of multicast packets dropped.

Unicast

Number of unicast packets dropped.

Total-Drop

Number of broadcast, multicast, and unicast packets dropped because the port broadcast limit was exceeded.

Shutdown

Status of whether the port was shut down because of security.

Trap

Status of whether the port trap is enabled or disabled.

IfIndex

Number of the ifIndex.

Broadcast-Limit

Broadcast threshold configured for the port.

Broadcast-Drop

Number of broadcast/multicast packets dropped because the broadcast limit for the port was exceeded.

Errdisable Reason

Reason for the port to be in errdisabled state.

Port ErrDisableTimeout

Status of errdisable timer timeout on the port.

Action on Timeout

Action that is taken on errdisable timer timeout.

Align-Err

Number of frames with alignment errors (frames that do not end with an even number of octets and have a bad CRC) received on the port.

FCS-Err

Number of valid size frames with FCS errors but no framing errors.

Xmit-Err

Number of transmit errors that occurred on the port (indicating that the internal transmit buffer is full).

Rcv-Err

Number of receive errors that occurred on the port (indicating that the internal receive buffer is full).

UnderSize

Number of received frames less than 64 octets long (but are otherwise well-formed).

Single-Coll

Number of times one collision occurred before the port transmitted a frame to the media successfully.

Multi-Coll

Number of times multiple collisions occurred before the port transmitted a frame to the media successfully.

Late-Coll

Number of late collisions (collisions outside the collision domain).

Excess-Col

Number of excessive collisions that occurred on the port (indicating that a frame encountered 16 collisions and was discarded).

Carri-Sen

Number of times the port sensed a carrier (to determine whether the cable is currently being used).

Runts

Number of received runt frames (frames that are smaller than the minimum IEEE 802.3 frame size) on the port.

Giants

Number of received giant frames (frames that exceed the maximum IEEE 802.3 frame size) on the port.

CE-State

Connection entity status.

Conn-State

Connection state of the port, as follows:

Disabled—The port has no line module or was disabled by the user.

Connecting—The port attempted to connect or was disabled.

Standby—The connection was withheld or was the inactive port of a dual-homing concentrator.

Active—The port made a connection.

Other—The concentrator was unable to determine the Conn-State.

Type

Type of port, such as A—A port and B—B port.

Neig

Type of port attached to this port. The neighbor can be one of these types:

A—A port

B—B port

M—M port

S—Slave port

U—The concentrator cannot determine the type of the neighbor port.

Ler Con

Status of whether the port is currently in a LER condition.

Est

Estimated LER.

Alm

LER at which a link connection exceeds the LER alarm threshold.

Cut

Usage Guidelines

The protocol conditions are as follows:

On indicates the port will receive all the flood traffic for that protocol.

Off indicates the port will not receive any flood traffic for that protocol.

Auto indicates the port will not receive any flood traffic for that protocol.

The GVRP registration status is defined as follows:

Normal allows dynamic registering and deregistering each VLAN (except VLAN 1) on the port.

Fixed supports manual VLAN creation and registration and prevents VLAN deregistration.

Forbidden statically deregisters all the VLANs (except VLAN 1) from the port.

When you enter the option keyword with any of the options (spantree | trunk | protcol | gmrp | gvrp | qos | rsvp | cops | dot1qtunnel | auxiliaryvlan | jumbo), associated VLANs and the specified feature-related parameters are displayed.

If you do not specify a mod or a port, EtherChannel information is shown for all PAgP channeling ports on all modules.

If you enter the all keyword, information about PAgP and LACP channels is displayed.
