How to Configure AToM VCs on the 4-Port ATM ISE Line Card Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers Step 5 Command or Action queue-limit number-of-cells cells Step 6 Example: Router(config-pmap-c)# queue-limit 300 cells exit Purpose Specifies or modifies the maximum number of cells the queue can hold for a class policy configured in a policy map. Exits class mode. Step 7 Example: Router(config-pmap-c)# exit exit Exits policy-map mode. Step 8 Example: Router(config-pmap)# exit interface atmslot/port Specifies an ATM interface or subinterface to configure. Step 9 Example: Router(config)# interface atm1/0 atm clock internal Causes the ATM interface to generate the transmit clock internally. Step 10 Example: Router(config)# atm clock internal atm mcpt-timers [timer1-timeout timer2-timeout timer3-timeout] Sets up the cell-packing timers, which specify how long the PE router can wait for cells to be packed into an MPLS packet. Example: Router(config-if)# atm mcpt-timers 100 1000 5000 You can set up to three timers. For each timer, you specify the maximum cell packing timeout (MCPT). This value gives the cell packing function a limited amount of time to complete. If the timer expires before the maximum number of cells are packed into an AToM packet, the packet is sent anyway. The range of values is from 2 to 4095. Step 11 pvc [name] vpi/vci l2transport Step 12 Example: Router(config-if)# pvc 21/21 l2transport encapsulation aal0 Step 13 Example: Router(config-atm-l2trans-pvc)# encapsulation aal0 cell-packing cells mcpt-timer timer Specifies a PVC with the specified VPI and virtual circuit identifier (VCI). The l2transport keyword indicates that the PVC is a switched PVC and not a terminated PVC. For ATM Cell Relay, this command specifies raw cell encapsulation for the interface. Make sure you specify the same encapsulation type on the PE and CE routers. Enables cell packing and specifies the cell packing parameters. Example: Router(config-atm-l2trans-pvc)# cell-packing 10 mcpt-timer 1 The cells value represents the maximum number of cells to be packed into an MPLS packet. The range is from 2 to 28. The timer value allows you to specify which timer to use. Cisco IOS Release 12.0(27)S 56

Cisco IOS Release 12.0(27)S
Step 5
queue-limit
number-of-cells
cells
Example:
Router(config-pmap-c)# queue-limit 300 cells
Specifies or modifies the maximum number of cells the
queue can hold for a class policy configured in a policy
map.
Step 6
exit
Example:
Router(config-pmap-c)# exit
Exits class mode.
Step 7
exit
Example:
Router(config-pmap)# exit
Exits policy-map mode.
Step 8
interface atm
slot/port
Example:
Router(config)# interface atm1/0
Specifies an ATM interface or subinterface to configure.
Step 9
atm clock internal
Example:
Router(config)# atm clock internal
Causes the ATM interface to generate the transmit clock
internally.
Step 10
atm mcpt-timers
[
timer1-timeout timer2-timeout
timer3-timeout
]
Example:
Router(config-if)# atm mcpt-timers 100 1000
5000
Sets up the cell-packing timers, which specify how long the
PE router can wait for cells to be packed into an MPLS
packet.
You can set up to three timers. For each timer, you specify
the maximum cell packing timeout (MCPT). This value
gives the cell packing function a limited amount of time to
complete. If the timer expires before the maximum number
of cells are packed into an AToM packet, the packet is sent
anyway. The range of values is from 2 to 4095.
Step 11
pvc
[
name
]
vpi/vci
l2transport
Example:
Router(config-if)# pvc 21/21 l2transport
Specifies a PVC with the specified VPI and virtual circuit
identifier (VCI). The
l2transport
keyword indicates that
the PVC is a switched PVC and not a terminated PVC.
Step 12
encapsulation aal0
Example:
Router(config-atm-l2trans-pvc)# encapsulation
aal0
For ATM Cell Relay, this command specifies raw cell
encapsulation for the interface. Make sure you specify the
same encapsulation type on the PE and CE routers.
Step 13
cell-packing
cells
mcpt-timer
timer
Example:
Router(config-atm-l2trans-pvc)# cell-packing 10
mcpt-timer 1
Enables cell packing and specifies the cell packing
parameters.
The
cells
value represents the maximum number of cells to
be packed into an MPLS packet. The range is from 2 to 28.
The
timer
value
allows you to specify which timer to use.
