Dear all,

We have two datacenters at different locations, there is one layer 3 connectivety and two later two connectivity establised.There are multiple vlans configured and segrecated into ODD & EVEN vlans.

ODD vlans would travers on one ODD later 2 trunk and even vlans traverse in another later 2 trunk, STP is enabled. I have an issue couple of days before that on of the layer 2 trunk got flapped and all the ODD vlan users got disconected from the network for littel while and got reconected.

Is there any way to find out STP recalcuation between these two trunk links, if yes please tell me how to do that.

Many thanks in advance.

"sh spanning-tree vlan xx detail" and look at

" Number of topology changes x last change occurred 1w1d ago"

if u are using STP, u ight want to try RSTP instead.
