DETAILED STEPS
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface type slot/port
Example:
Router(config)# interface ATM
4/1
Specifies the interface by type, slot, and port number, and enters interface
configuration mode.
Step 4
atm mcpt-timers
[timeout-value-1
timeout-value-2
timeout-value-3]
Example:
Router(config-if)# atm
mcpt-timers 10 100 1000
(Optional) Sets up the cell-packing timers, which specify how long the PE
router can wait for cells to be packed into an L2TPv3 packet.
Step 5
cell-packing [cells]
[mcpt-timer timer]
Example:
Router(config-if)# cell-packing
10 mcpt-timer 2
Enables the packing of multiple ATM cells into each L2TPv3 data packet.
• cells—(Optional) The number of cells to be packed into an L2TPv3 data
packet. The default number of ATM cells to be packed is the maximum
transmission unit (MTU) of the interface divided by 52.
• mcpt-timer timer—(Optional) Specifies which maximum cell packing
timeout (MCPT) timer to use. The MCPT timers are set using the
mcpt-timers command. The default value is 1.
Step 6
xconnect peer-ip-address vcid
pseudowire-parameters
[sequencing {transmit | receive
| both}]
Example:
Router(config-if)# xconnect
10.0.3.201 888 encapsulation
l2tpv3
Binds an attachment circuit to a Layer 2 pseudowire and enters Xconnect
configuration mode.
