lre profile
lre profile
Use the lre profile global configuration command to assign a Long-Reach Ethernet (LRE) profile to all
switch LRE ports. Use the no form of this command to remove the profile.
lre profile profile-name
no lre profile profile-name
This command is available only on Catalyst 2950 LRE switches.
Syntax Description
Defaults The default for the Catalyst 2950ST-8 LRE and 2950ST-24 LRE switches is LRE-10. The default for the
Catalyst 2950ST-24 LRE 997 switch is LRE-6.
Command Modes Global configuration
Command History
Usage Guidelines Unless you assign a profile, the switch uses the default global profile. The LRE-10 profile allows the
upstream and downstream transmission rate on the LRE link to be 12.5 Mbps. The LRE-6 profile allows
the upstream and downstream transmission rate on the LRE link to be 6.25 Mbps. Profiles assigned at
the port level have priority over profiles assigned at the global level.
When assigning profiles to LRE ports, keep these considerations in mind:
• The default profile might not be the best choice for your environment.
• When you assign a different profile to a port, the port applies and uses the newly-assigned profile.
• If a Catalyst 2950ST-8 LRE or 2950ST-24 LRE switch is used with equipment directly connected to
a public switched telephone network (PSTN) without a public branch exchange (PBX) between the
LRE switch and the public telephone lines, Cisco recommends that you use either the
LRE-998-15-4-M2 or LRE-997-10-4-M2 profiles globally.
Examples This example shows how to specify the LRE-8 profile on a Catalyst 2950ST-8 LRE or 2950ST-24 LRE
switch:
Switch# configure terminal
Switch(config)# lre profile lre-8
You can verify your settings by entering the show controllers lre profile details privileged EXEC
command.
profile-name Name of the profile. The profile name can be a Cisco-supplied profile or a
user-created profile. For more details on Cisco-supplied profiles, see the
software configuration guide for this release.
