Configuring VC Mode ATM Cell Packing over L2TPv3
Perform this task to configure VC mode ATM cell packing over L2TPv3.
SUMMARY STEPS
1. enable
2. configure terminal
3. interface type slot/port
4. atm mcpt-timers [timeout-value-1 timeout-value-2 timeout-value-3]
5. pvc [name] vpi/vci [ces | ilmi | qsaal | smds | l2transport]
6. encapsulation aal0
7. cell packing [cells] [mcpt-timer timer]
8. xconnect peer-ip-address vcid pseudowire-parameters [sequencing {transmit | receive | both}]
DETAILED STEPS
Step 6
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 MTU of the
interface divided by 52.
• mcpt-timer timer—(Optional) Specifies which MCPT timer to use. The
MCPT timers are set using the mcpt-timers command. The default value
is 1.
Step 7
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.
