Chapter 4 Configuring Interfaces
Configuring the ATM Uplink Interface (Catalyst 8540)
To create a PVC, perform the following steps, beginning in global configuration mode:
| Command | Purpose |
Step 1 |
|
|
Router(config)# interface atm | Enters interface configuration mode and specifies the ATM | |
| slot/subslot/interface | interface to configure. |
|
| |
Step 2 |
|
|
Configures the PVC with VCD value associated with a VPI/VCI | ||
| vpi vci | pair and specifies an encapsulation type. |
|
|
|
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 ATM NSAP 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:
| Command | Purpose |
Step 1 |
|
|
Router(config)# | Creates a map list and assigns it a name. | |
Step 2 |
|
|
Creates one or more map list entries, associating a protocol | ||
|
| address with a VCD. |
Step 3 |
|
|
Exits | ||
| Router(config)# |
|
Step 4 |
|
|
Router(config)# interface atm | Enters interface configuration mode and specifies the ATM | |
| slot/subslot/interface | interface to configure. |
|
| |
Step 5 |
|
|
Associates the map list with the interface. | ||
| name |
|
|
|
|
You can 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)#
Router(config-map-list)# 1.1.1.5 atm-vc 5 broadcast
