spe recovery {port-action {disable | recover | none} | port-threshold num-failures}
When an SPE port fails to connect for a certain number of consecutive times, a problem exists in a
specific part or the whole of SPE or firmware. Such SPEs have to be recovered by downloading
firmware. Any port failing to connect num-failures times is moved to a state based on port-action, where
you can choose to disable (mark the port as Bad) or recover the port when the SPE is in the idle state
and has no active calls. The default for num-failures is 30.
You can also schedule recovery using the spe download maintenance configuration command.
SPE Download Maintenance
You can configure a scheduled recovery of SPEs from global configuration mode (the prompt is
AS5350(config)#
spe download maintenance time hh:mm | stop-time hh:mm | max-spes num-of-spes | window
time-period | expired-window {drop-call | reschedule}
Download maintenance starts at time, steps through all the SPEs that need recovery and SPEs that need
a firmware upgrade, and starts maintenance on max-spes at a time. It waits for the window delay time
for all the ports on the SPE to become inactive before moving the SPE to the idle state. It downloads
firmware immediately after the SPE moves to idle. If the ports are still in use by the end of window,
depending on the expired-window setting, connections on the SPE ports are shut down and the firmware
is downloaded by choosing the drop-call option, or the firmware download is rescheduled to the next
download maintenance time by choosing the reschedule option. This process continues until the number
of SPEs under maintenance is below max-spes, or until stop-time (if set), or until all SPEs marked for
recovery or upgrade have had their firmware reloaded. The default download-maintenance time is 0300.
Clear an SPE
The clear spe privileged EXEC mode command allows you to manually recover a port that is frozen in
a suspended state. This command causes the firmware configured for that SPE to be downloaded to the
specified SPE or the range of SPEs and power-on self test (POST) to be executed. This command can be
executed regardless of the state of the SPEs. All active ports running on the SPE are prematurely
terminated and messages are logged into the appropriate log. This replaces the clear modem command.
The following example shows a cold start on SPE 1 on slot 1:
AS5400# clear spe 1/1
AS5400# Are you sure you want to clear SPE 1/1(Y/N)? Y
Upgrading SPE Firmware
With new systems, Cisco loads a Cisco IOS software-compatible version of SPE firmware into each
installed SPE. A map of the version or versions of SPE firmware copied to RAM for each SPE is stored
in nonvolatile random-access memory (NVRAM) so that it is retained over power cycles.
You do not have to take any action to use the preinstalled version of SPE firmware with new systems.
Note
You can acquire new SPE firmware from the Cisco Software Center in one of two ways:
