Use the rates and distances in
type of cable you use, how it is bundled, and the interference and noise on the
LRE link can affect the actual LRE link performance. Contact Cisco Systems
for information about limitations and optimization of LRE link performance.

When assigning a profile to an LRE port, keep the following considerations in
mind:
An LRE port always has a private profile assigned to it. However, 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. If you
assign a different public profile, the change immediately takes effect.
If a public profile is configured on the switch and you want the LRE ports to
use private profiles, you must first disable the public profile by using CMS
or by using the no lre profile global global configuration command.
If no public profile is configured on the switch, the LRE port uses its private
profile. If you assign a different private profile to the LRE port, the change
immediately takes effect.
