Configuring an ATM subinterface
Configuring an ATM subinterface
To configure an ATM subinterface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an ATM subinterface
and enter its view.
interface atm
interface-number.subnumber
[ p2mp | p2p ]
By default, the connection type of
an ATM subinterface is
point-to-multipoint (P2MP).
3. Set the MTU for the ATM
subinterface.
mtu mtu-number
Optional.
1500 bytes by default.
4. Shut down the ATM
subinterface.
shutdown
Optional.
By default, ATM subinterfaces are
up.
CAUTION:
The keywords p2mp and p2p are available with the interface atm interface-number.subnumber only
when you are creating an ATM subinterface. If you are entering an existing ATM subinterface, the two
keywords are not available.
