show controllers lre status
show controllers lre status
Use the show controllers lre status privileged EXEC command to display the Long-Reach Ethernet
(LRE) link statistics and profile information on a switch LRE port, including link state, link duration,
profile name, and data rates.
show controllers lre status {cpe | interleave | link | profile | psd | sequence [detail]} [interface-id]
[ | {begin | exclude | include} expression]
This command is available only on Catalyst 2950 LRE switches.
Syntax Description
Command Modes Privileged EXEC
Command History
Usage Guidelines Use the show controllers lre status privileged EXEC command to display the status of all switch LRE
ports.
Use the signal-to-noise ratio (SNR) and Reed-Solomon error information to measure the quality of the
LRE link. The SNR represents the amount of increased received signal power (in decibels) relative to
the noise power-level that the switch can tolerate without disconnecting from the CPE device. The higher
the ratio, the more resilient is the link.
cpe Display information about the customer premises equipment (CPE) 10/100 Ethernet
ports.
interleave Display the interleave block size values on the LRE interfaces.
link Display the various parameters and status associated with the LRE link.
profile Display the various administrative parameters and status associated with the LRE
link.
psd Display the power-related status.
sequence Display the status of profiles in a sequence. Possible status values are converged,
waiting on link, executing, and locked.
detail (Optional) Display additional information about the sequences, such as margins,
locked profiles, and convergence times.
interface-id (Optional) ID of the switch LRE port.
| exclude (Optional) Display excludes lines that match the specified expression.
| include (Optional) Display includes lines that match the specified expression.
expression Expression in the output to use as a reference point.
