The VLAN-aware bridge mode only currently supports RSTP, Cisco 4500X use PVRSTP+.

On the cisco side create your trunk, and be sure to add vlan 1 to the switchport trunk allowed list. This will allow the IEEE RSTP BPDUs into the cisco trunk. The cisco side will recognize the standards-based switch and interoperate. Remember the spanning-tree on the cumulus side will not honor any of the per-vlan STP topologies, only vlan 1.
