Checking status with the Rearslot command
The
rearslot
command shows the status of all the slots used for LPMs, PSMs, and CLT
modules. It also reports on the status of the midplane redundancy bus. Slots that are equipped
with IRMs or LPM-Rs are reported as
Empty
by the
rearslot
command.
Note:
When a copper loop is being tested on a Stinger LS with a PSM or a CLT module, the
rearslot
command does not display any midplane sparing bus usage.
For example, suppose that a Stinger FS is equipped with ADSL LIMs and SDSL LIMs. The
ADSL 24-port LIM in slot 1 has failed and is being replaced by the ADSL 24-port LIM in
slot 14. The
rearslot
command reports the following.

Configuring LIM port redundancy
LIM port redundancy allows an individual port of a LIM to be backed up by the corresponding
port of a spare LIM. The LIM to be backed up (the primary LIM) must be of the same type as
sparing-state
State of the redundancy function. If redundancy is not
enabled,
sparing-none
is the value. If redundancy is
enabled and the LIM slot is a primary LIM, the value can
be
primary-active
or
primary-inactive
. If
redundancy is enabled and the LIM slot is the secondary
(spare) LIM, the value can be
secondary-active
or
secondary-inactive
. A value of
not-applicable
indicates that LIM redundancy is not
applicable to this module.
