Chapter4 Configuring Interfaces Configuring the ATM Uplink Interface (Catalyst8540)
To create a PVC, perform the following steps, beginning in global configuration mode:
The atm pvc command allows you to specify additional optional parameters for the connection,
including peak, average, and burst transmission rate, and the frequency for generating OAM cells.
Mapping a Protocol Address to a PVC
Cisco IOS supports a mapping scheme that allows you to associate a protocol address with a VCD (for
PVCs) or with an ATMNSAP address (for SVCs). To create a mapping, you first create a map list, then
associate the map list to an interface.
To map a protocol address to a PVC, perform the following steps, beginning in global configuration
mode:
Youcan create multiple map lists. An interface can have only one map list associated with it, but a map
list can be associated with multiple interfaces.

PVC Example

In the following example, PVC 5 is created on ATM interface 1/0/0 by means of LLC/sNAP
encapsulation over AAL5. ATM interface 1/0/0 (IP address 1.1.1.1) connects with the ATM interface
(IP address 1.1.1.5) at the other end over VC 5.
Router(config)# interface atm 1/0/0
Router(config-if)# ip address 1.1.1.1 255.255.255.0
Router(config-if)# atm pvc 5 0 10 aal5snap
Router(config-if)# map-group atm
Router(config-if)# exit
Router(config)# map-list atm
Router(config-map-list)# 1.1.1.5 atm-vc 5 broadcast
Command Purpose
Step1 Router(config)# interface atm
slot/subslot/interface
Router(config-if)#
Enters interface configuration mode and specifies the ATM
interface to configure.
Step2 Router(config-if)# atm pvc vcd
vpi vci aal-encap Configures the PVC with VCD value associated with a VPI/VCI
pair and specifies an encapsulation type.
Command Purpose
Step1 Router(config)# map-list name Creates a map list and assigns it a name.
Step2 Router(config-map-list)# ip
ip-address atm-vc vcd Creates one or more map list entries, associating a protocol
address with a VCD.
Step3 Router(config-map-list)# exit
Router(config)#
Exits map-list configuration mode.
Step4 Router(config)# interface atm
slot/subslot/interface
Router(config-if)#
Enters interface configuration mode and specifies the ATM
interface to configure.
Step5 Router(config-if)#map-group
name Associates the map list with the interface.
