Cisco 45xx Supervisor 6LE Defect

Fri, 27 Jan 2017 09:00:05 +0000

As I tend to work with some Cisco 4506 and similiar switches - equipped with WSX45SUP6LE / WS-X45-SUP6L-E Supervisor Engines, I had the unfortunate delight to seem those rebooting at random.

Cisco did put out an entry in their bug tool (“Sup6LE reloads silently (Reset State: 00000201) / watchdog CISR0: 0x80”) with the Bug Tracker ID CSCtf85481 - however, of the multiple accounts I had, I only found it on one of those. Other accounts did refuse my access to this file. As we confronted our Cisco Tech Support prior to finding the bug ourself, there was “no known error” which represented itself in rebooting the switch at random - so they said.
