show port

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

show port [mod_num[/port_num]]

Syntax Description

mod_num	(Optional) Number of the module. If you do not specify a number, the ports on all modules are shown.
/port_num	(Optional) Number of the port on the module. If you do not specify a number, all the ports on the module are shown.

Default

This command has no default setting.

Supported Platforms

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

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

In the status field for the Catalyst 5000 family, 4000 family, 2926G series, and 2948G switch ports, the following applies:

connected indicates the port is operational.

Note

connected

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 switch is a fixed configuration switch. All ports are located on module 2; for this reason, if you enter mod_num/port_num 1/N, an error message will be displayed.

FCS-Err

Number of frame check sequence errors that occurred on the port.

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).

show protocolfilter

Use the show protocolfilter command to list whether protocol filtering is enabled or disabled.

show protocolfilter

Syntax Description

This command has no keywords or arguments.

Default

This command has no default setting.

Supported Platforms

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

Command Type

Switch command.

Command Mode

Normal.

Usage Guideline

This command is not supported by the three-port Gigabit Ethernet switching module (WS-X5403).

Example

This example shows how to display whether protocol filtering is enabled or disabled:

Console> show protocolfilter
Protocol filtering is enabled on this switch.
Console>

Related Command

set port protocol

show qos info

Use the show qos info command to display QoS-related information for a specified port.

show qos info {runtime | config}
show qos info {runtime | config} mod_num/port_num
show qos info config port_type tx

Syntax Description

runtime	Keyword to show the current QoS run time information.
config	Keyword to show the NVRAM setting of QoS.
mod_num /port_num	Number of the module and the port.
port_type	QoS port type. Valid port type is 1q4t.
tx	Keyword to specify the transmit drop threshold.

Default

This command has no default setting.

Supported Platforms

Catalyst 5000 family switches
Catalyst 4000 family switches
Catalyst 2948G switch

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

On the Catalyst 5000 family switches, this command is supported only with Supervisor Engine II G or III G, or Supervisor Engine III or III F with the NFFC II.

The mod_num /port_num argument, the port_type argument, and the tx keyword are not supported on the Catalyst 4000 family and 2948G switches.

The display of show qos info runtime shows both the absolute values and the percentages you specified for the drop thresholds, queue sizes, and WRR. However, the absolute values may not exactly match the percentages specified due to the granularity of permitted settings in hardware.

On the Catalyst 5000 family switches, the transmit drop threshold percentages specified select a buffer usage level where each threshold applies. The percentages to buffer usage level are as follows:

1% is a threshold when 2,044 bytes of the transmit queue buffer have been used
2% and 3% = 4,092 bytes have been used
4% through 7% = 8,188 bytes have been used
8% through 14% = 16,380 bytes have been used
15% through 28% = 32,767 bytes have been used
29% through 57% = 65,532 bytes have been used
58% through 100% = 131,068 bytes have been used

The number preceding the t in the port-type determines the number of threshold values that the hardware supports. For example, with 1q4t, four thresholds are specified. The number preceding the q in the port-type determines the number of the queues that the hardware supports. For example, with 1q4t, one queue is specified.
