Chapter 7      Configuring the Switch Ports
Configuring the LRE Ports
Assigning a Public Profile to All LRE Ports
Public profiles are set on a switch-wide (global) basis. The public profile you 
select should be compatible with the PSTN to which the LRE switch is connected.
Public profiles have priority over private profiles. If you assign a public profile to 
the switch, the switch ignores the private profile settings and uses the public 
profile settings on all LRE ports. To disable the public profile on the switch, use 
the no lre profile global global configuration command.
Changes to the public profile settings are immediately put in effect, and the public 
mode automatically becomes the active mode.
Beginning in privileged EXEC mode, follow these steps to assign a public profile 
to the LRE ports:
Use the show controllers lre commands to display the LRE link statistics and 
profile information on the LRE ports. For information about these commands, 
refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command 
Reference.
