Chapter 12 Using Access Control
Configuring a Template Alias
During initial configuration, perform the following steps to use access control to filter setup messages:
Step 1 Create a template alias allowing you to use real names instead of ATM addresses in your ATM filter
expressions.
Step 2 Create the ATM filter set or filter expression based on your requirements.
Step 3 Associate the filter set or filter expression to an interface using the atm atm access-group command.
Step 4 Confirm the configuration.
Configuring a Template Alias
To configure an ATM template alias, use the following command in global configuration mode:
Examples
The following example creates a template alias named training using the ATM address template 47.1328
and the ellipses (...) to fill in the trailing 4-bit hexadecimal digits in the address:
Switch(config)# atm template-alias training 47.1328...
The following example creates a template alias named bit_set with the ATM address template
47.9f9.(1*0*).88ab... that matches the four addresses that begin with the following:
• 47.9F9(1000).88AB... = 47.9F98.88AB...
• 47.9F9(1001).88AB... = 47.9F99.88AB...
• 47.9F9(1100).88AB... = 47.9F9C.88AB...
• 47.9F9(1101).88AB... = 47.9F9D.88AB...
Switch(config)# atm template-alias bit_set 47.9f9(1*0*).88ab...
The following example creates a template alias named byte_wise with the ATM address template
47.9*F8.33... that matches all ATM addresses beginning with the following sixteen prefixes:
• 47.90F8.33...
through
• 47.9FF8.33...
Switch(config)# atm template-alias byte_wise 47.9*F8.33...
