LRE Link Messages
This section contains the LRE Link error messages.
LRE_LINK-3-UPDOWN: Interface changed state to up or down
Explanation This message means that the link between the LRE port and the
CPE device has been lost and that no Ethernet traffic is being transferred. This
could be the result of reconfiguring the port, reconfiguring a profile in use by
this port, a physical disconnection or reconnection of the LRE connector on
the switch, or by someone disconnecting the CPE LRE cable or cycling its
power. It might also be caused by any substantial interruption of the signal or
cabling between the LRE port and the CPE.
Action If someone is reconfiguring the port or the profile in use, ignore this
message. However, if the LRE link does not go back up within a minute or so,
it could mean a physical disconnection at the switch or CPE or a loss of power
to the CPE.
LRE_LINK-3-PROFILE_FAILURE: Interface, profile failure
Explanation
When the switch reloads or when the LRE link is lost, the LRE
port first attempts to briefly establish link with the CPE in a common, reduced
rate mode. This is so that the switch can exchange configuration information
