If you are using a untagged VLAN and STP, then this should work. You should then be able to check the STP status on ports from/to the Cat.

The default mode of spanning tree operation of Avaya switches is Avaya Spanning Tree mode, which determines how you handle STP packets on tagging on the links. This is generally compatable with most vendors, but there are ways in which Cisco can tag STP BPDU such that they will not be appropriate handles by the switch.

You may want to look at using something like MSTP mode (802.1s) on both switches which sets the switch to using standard based multiple Spanning Tree.
