Configure the expected
bandwidth for the
interface.

bandwidth-value
By default, the expected bandwidth
(in kbps) is the interface baud rate
divided by 1000.
6.
Bring up the Ethernet
subinterface.

By default, Ethernet subinterfaces are
in up state.
Configuring the link mode of an Ethernet interface
CAUTION:
After you change the link mode of an Ethernet interface, all commands (except the
shutdown
command)
on the Ethernet interface are restored to their defaults in the new link mode.
The interfaces on this switch series can operate either as Layer 2 or Layer 3 Ethernet interfaces (you can
set the link mode to bridge or route).
To change the link mode of an Ethernet interface:

Configuring jumbo frame support
An Ethernet interface might receive some frames larger than the standard Ethernet frame size (called
"jumbo frames") during high-throughput data exchanges, such as file transfers. The interface processes
jumbo frames in the following way:
•
When the Ethernet interface is configured to deny jumbo frames (by using the
undo jumboframe
enable
command), the Ethernet interface discards jumbo frames without further processing.
•
When the Ethernet interface is configured with jumbo frame support, the Ethernet interface
processes frames as follows:
