Considerations For Connected Cisco 585 Lre Cpes; Assigning A Public Profile To All Lre Ports - Cisco WS-C2955T-12 Software Manual

Configuring the LRE Ports

Considerations for Connected Cisco 585 LRE CPEs

You cannot configure the Cisco 585 LRE CPE Ethernet ports.
The default speed for the CPE Ethernet ports is auto. The default duplex mode is half duplex with back
pressure. Duplex autonegotiation is not supported on the Cisco 585 LRE CPE.
You cannot enable or disable the CPE Ethernet ports on a per-port basis. For example, using the
shutdown interface configuration command on an LRE port disables all Ethernet ports on the connected
CPE.
The loopback interface configuration command is not supported on the LRE ports. External loopback
on the LRE ports is also not supported. Connecting a CPE Ethernet port to another Ethernet port on the
same CPE can create a loop. If this happens, the switch stops sending to the CPE and blocks Ethernet
traffic coming from the CPE.

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:
Command
Step 1 configure terminal
Step 2
lre profile global profile_name
Step 3
end
Step 4
show controllers lre profile
mapping
Use the show controllers lre privileged EXEC commands to display the LRE link statistics and profile
information on the LRE ports. For information about these commands, refer to the switch command
reference.

Purpose
Enter global configuration mode.
Enter the public profile name: PUBLIC-ANSI or PUBLIC-ETSI.
Return to privileged EXEC mode.
Verify the change.
