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 a "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; the show commands do not display the channel. With LACP, when all the ports in a channel get disabled, LACP does not remove the channel; the 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 when you use the show port command and as not connected when you use the show spantree command. This discrepancy is because the port is physically connected but has 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, see the "Configuring EtherChannel" chapter of the Catalyst 6500 Series Switch Software Configuration Guide.

Table 2-69 describes the possible fields (depending on the port type queried) in the show port command output.

Table 2-69 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.

show port prbs

To display the ports that are running the Pseudo Random Binary Sequence (PRBS) test and to display the counter values for ports on which the test has run, use the show port prbs command.

show port prbs [mod[/port]]

show port prbs vlan [vlan | vlan_name]

Syntax Description

mod	(Optional) Number of the module.
port	(Optional) Number of the port on the module.
vlan	Limits output to ports in the specified VLAN.
vlan	(Optional) VLAN number; valid values are from 1 to 4094.
vlan_name	(Optional) VLAN name.

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 PRBS error counter measures the reliability of the cable. The error counter range is 0 to 255. A value of 0 signifies a perfect link connection. A value of 255 signifies that the port is faulty or not connected or that there is no communication through the link. If the counter does not remain at zero for a predetermined length of time, the link is faulty. For example, for a baud error rate (BER) of 10^-12, the counter should remain at zero for 100 seconds.

Each time you access the PRBS counter by entering the show port prbs command, the PRBS error counter value is reset to 0, and the counter begins to accumulate errors again.

---

Note The PRBS counter is a "read and clear" register: the first reading in a sequence is usually unreliable and serves primarily to purge the counter; successive readings are accurate.

---

Examples

This example shows how to display PRBS counter values and the ports that are running the PRBS test:

Console> show port prbs

Max error counters = 255

show port security-acl

To display the port access control list (PACL) mode and the status of a PACL merge operation, use the show port security-acl command.

show port security-acl mod/port

Syntax Description

mod/port

Number of the module and the port on the module.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

The show port security-acl command displays PACL information for a specific port. The command output displays both configuration and runtime information. Configuration information shows what is stored in the NVRAM; runtime information shows what is programmed in the hardware.

The output also displays the status of the merge operation. The status can be as follows:

•active—There is a PACL configured on the port and it is successfully merged with the VLAN.

•inactive—There is no PACL configured on the port.

•disabled—There is a PACL configured on the port, but the merge was unsuccessful (for any number of reasons).

The show port security-acl command also displays the VLAN with which the port is configured to merge.
