Port configuration

Use the port configuration commands to configure settings for individual switch ports.

NOTE: Port 19 is reserved for switch management.

The following table describes the Port Configuration commands. The following sections provide more detailed information and commands.

Table 76 Port Configuration commands

Description

Enter Interface Port configuration mode for the selected port.

Command mode: Global configuration

Sets the default VLAN number which will be used to forward frames which are not VLAN tagged. The default number is 1.

NOTE: VLAN 4095 is reserved for switch management.

Command mode: Interface port

name {<1-64 characters>}

Sets a name for the port (maximum 64 characters). The assigned port

 

name displays next to the port number on some information and statistics

 

screens.

 

Command mode: Interface port

[no] rmon

Enables or disables Remote Monitoring for the port. RMON must be

 

enabled for any RMON configurations to function.

 

Command mode: Interface port

[no] tagging

Disables or enables VLAN tagging for this port. It is disabled by default.

 

Command mode: Interface port

[no] tag-pvid

Disables or enables VLAN tag persistence. When disabled, the VLAN tag is

 

removed from packets whose VLAN tag matches the port PVID. The default

 

value is enabled.

 

Command mode: Interface port

no shutdown

Enables the port.

 

Command mode: Interface port

shutdown

Disables the port. To temporarily disable a port without changing its

 

configuration attributes, see the “Temporarily disabling a port” section later

 

in this chapter.

 

Command mode: Interface port

show interface

Displays current port parameters.

gigabitethernet {<port

Command mode: All

number>}

 

Temporarily disabling a port

To temporarily disable a port without changing its stored configuration attributes, enter the following command at any prompt:

Switch# interface gigabitethernet <port number> shutdown

Because this configuration sets a temporary state for the port, you do not need to perform a save operation. The port state reverts to its original configuration when the switch is reloaded.
