Hi,
We have ERS 8600 cluster connected to Cisco 2960 stack.
We have some VLAN's configured and it works till we use one cable in between sack and cluster. We have no VLAN 1 on this connection.
On ERS we have enabled rstp, on Cisco is PVST.
As soon as I connect second cable to Cisco I'm loosing connection at all(there probably some loop)
I'm not sure what I need to change in ERS configuration to get it .
I have read through NN48500-604 "PVST+ Technical Configuration Guide" but I can't find clear answer what I must to do.
Does some one use similar configuration and can share experience?
Regards,
Darius
