Usage Information
The shutdown command marks a physical interface as unavailable for trac. To discover if an interface is
disabled, use the show ip interface brief command. Disabled interfaces are listed as down.
Disabling a VLAN or a port channel causes dierent behavior. When a VLAN is disabled, the Layer 3
functions within that VLAN are disabled. Layer 2 trac continues to ow. Entering the shutdown
command on a port channel disables all trac on the port channel and the individual interfaces within the
port channel. To enable a port channel, enter no shutdown on the port channel interface and at least one
interface within that port channel.
The shutdown and description commands are the only commands that you can congure on an
interface that is a member of a port channel.

speed (for 10/100/1000 interfaces)

the link may not come up.
Syntax
speed {10 | 100 | 1000 | auto}
To return to the default setting, use the no speed {10 | 100 | 1000} command.
Parameters
10 Enter the keyword 10 to set the interface’s speed to 10 Mb/s.

LC-EJ-GE-50P card. If the command is entered for these interfaces, an
error message appears.
