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:

Modification
This command was introduced.
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.
