My main switch is the following:

The management vlan for these are on vlan 25.  The problem is that when I connect to main switch via ssh and then rcommand to switch 1 or 2, sometimes I loose my connection to the switches and my ssh connection is just cut.  When I login to the main switch I see that the member is down and keeps this for a couple of seconds (+- 25 seconds).

Can this be a configuration issue?

thanks

Can u Post Config

Jawad

do you mean the entire config?

I think the most important configuration is how both are connected right?

switch 1:

cluster enable wijgmaal 0

cluster member 1 mac-address 001f.9d2d.9f80

cluster member 2 mac-address 001f.9e2c.2180

no spanning-tree vlan 25

interface TenGigabitEthernet1/0/1

description to 2nd switch 10thfloor

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 25,100-160,250-252

switchport mode trunk

mls qos trust dscp

interface Vlan25

switchport trunk encapsulation dot1q

Hope this is enough information?

When the switch via rcommand is down, I can however connect to it via ssh on it's ip 192.168.25.4

You're have 3750 and you're running switch clustering????  How quaint.

I'm suspecting that your stack cables are not cabled up properly or you have a stack module failure. 

Hi the cabling was done correctly so the problem is not related to this.
