3750 stack switches not showing up when issuing show commands

r.crist
Level 1
Level 1

We have several stacks of 3750 switches where this problem is occurring.  All of the switches are running IOS version 12.2(50)SE3.  (Yes, I know it's old.)

We're seeing inconsistency in how the stack reports members when issuing the following commands:

show switch

show version

show inventory

Not all members are showing up in the output of the "show version" and "show inventory" commands.  For example:

HUNTI-WV-WDAC03#sh switch

                                           H/W   Current

Switch#  Role   Mac Address     Priority Version  State

----------------------------------------------------------

1       Member 108c.cff2.ea00     15     0       Ready              

2       Member 8cb6.4f0a.a600     1      0       Ready              

*3       Master 8cb6.4f0a.9c00     1      0       Ready

(all three switches in stack are displayed)

HUNTI-WV-WDAC03#sh version
... <output truncated>

Switch Ports Model              SW Version            SW Image

Switch 02

(switch 3 is not displayed)

HUNTI-WV-WDAC03#sh inventory

NAME: "1", DESCR: "WS-C3750V2-48PS"
PID: WS-C3750V2-48PS-S , VID: V06, SN: FDO1449X2G0

(switch 2 is not displayed)

Has anyone else seen these symptoms?  I searched the bug toolkit and was unable to find a match.

It sounds like an IOS bug.

I know you've searched for the bug in the toolkit but NOT ALL bugs are published.  There are some internal bugs that are left out.

I have the same problem. The problem started two days ago but in only one of the cisco 3750 I own. Both switches has the same ios version same settings etc etc.

Our on-site Cisco engineer said that this was a bug, and recommended that we upgrade IOS.  Which we did.  I haven't seen the problem since.  We upgraded to 12.2(55)SE7
