Intermittent SSH access to N1548 stack
I have a stack of 4 x N1548 switches to which I connect to using SSH for management.
However I keep loosing connectivity and running a ping to the address of the stack shows that the pings will respond for around half a minute then fail for around another half a minute then cycle around again. The up and down times are not regular and this is only affecting access to the switch management.
Devices connected to the stack are able to access other devices on other parts of my network without interruption and visa versa.
This is only affecting this one stack which I have yet to deploy, I have a couple of dozen others in my network.
Does anyone have any idea why this should be happening to this stack?

Hi Andrew,
Is the firmware of the stack up to date? Are you directly connected to the switch from the management PC? Is management on its own VLAN? Let us know if you have any additional questions.

Apologies for not getting back to you sooner.
Yes I have upgraded from 6.3.3.14 to 6.6.0.24, but that didn't make any difference. We have all our switches on the same VLAN and this isn't affecting any of the other stacks.
It would appear that it is something to do with routing as If I ping the stack from the same VLAN as the stack there doesn't appear to be an issue, it's only intermittent when trying to access the stack from a different VLAN (and subnet) through our router.
Accessing other stacks on the same VLAN as the one having problems doesn't cause any issues.
Any idea why this should be the case?

There isn’t a duplicate ip or a loop in the network is there?
