Chapter 12 Configuring LRE
Understanding LRE Features
LRE Sequences
The LRE switches are shipped with predefined sequences. Sequences are sets of profiles and are used
with the rate selection feature. The rate selection feature enables the switch to automatically select
profiles. You can also define your own sets of sequences by using the command-line interface (CLI)
commands. For more information, see the “Using Rate Selection to Automatically Assign Profiles”
section on page 12-14.
Table 12-3 and Table 12-4 list the predefined sequences for rate selection contained in the software.
When executing rate selection, the switch uses a sequence to choose an appropriate profile for a given
LRE interface.
