Administering ATM ARP Servers 10-13
Administering
ATM ARP Servers
If you are running classical IP over ATM with SVCs, follow these rules:
■
You must define an ATM ARP server for each LIS.
■
Each LIS must connect to a single ATM network.
■
Each LIS must belong to the same IP subnetwork.
The
atmArpServer
menu also includes the
arp
option, which allows you
to administer the ATM ARP cache.
Displaying ATM
ARP Servers
To display a list of ATM ARP servers, from the top level of the
Administration Console, enter:
ip atmArpServer display
Example:
Defining an ATM ARP
Server
Determine the location of the ATM ARP server that you want to use. You
can define the ATM ARP server externally on another CoreBuilder 2500
system or on an ATM switch, such as 3Com’s CoreBuilder 7000 system.
1 To define an ATM ARP server, from the top level of the Administration
Console, enter:
ip atmArpServer define
2 Enter the number of the ATM port on which you want to define the ATM
ARP server.
3 Enter the IP address of the ATM port that you want to define.
4 Enter the subnet mask. To accept the existing or default value shown in
brackets, press Return.
Example:
Select ATM port [1]
Enter IP address: 158.101.20.30
Enter subnet mask [255.255.0.0]
