Configuring LRE Ports

Configuring LRE Link Monitor

When link monitor is enabled, an LRE switch feature tracks undesirable or interesting conditions on a
link or takes system-defined actions after certain thresholds are reached.
Beginning in privileged EXEC mode, follow these steps to enable link monitor:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
link monitor
Step 4 end
Step 5 show running-config
Step 6
copy running-config startup-config
To disable the link monitor feature, use the no link monitor interface configuration command.

Configuring LRE Interleave

The interleave feature provides maximum protection against small interruptions on the LRE link but
delays data transmission. You can configure the interleave delay on LRE interfaces.
A lower value of the interleave block size means less tolerance to noise and causes a lower latency of
frame transmission. For example, lower values of the interleave block size can be used for voice
applications. A higher value of the interleave block size means higher tolerance to noise and causes
higher latency in the frame transmission. For example, higher values of the interleave block size can be
used for data applications.
If a lower latency of frame transmission is required, you can use a lower interleave value, but the LRE
switch will have less tolerance to noise.
Follow these guidelines for configuring the interleave delay:

Interleave delay is applicable only when the non-LL profiles are used. Existing LL profiles are
supported.
Interleave block size values of 0, 1, 2, 8, or 16 are supported.
Different ports with the same profile can have different interleave settings.
Purpose
Enter global configuration mode.
Specify the LRE port to be configured, and enter interface
configuration mode.
Enable LRE link monitoring on an LRE port.
Return to privileged EXEC mode.
Verify the change.
(Optional) Save your entries in the configuration file.
