RSTP Interoperability with Cisco PVST+


Article Summary: This article provides information on PowerConnect RSTP interoperability
with Cisco PVST+.

Problem:


PowerConnect spanning-tree mode RSTP is not functioning properly with Cisco switches using spanning-tree mode PVST+.

Solution:


On 802.1Q trunk links connecting PowerConnect switches to Cisco switches VLAN 1 must be added on both sides regardless of the native VLAN configured.

Additional Information:
Cisco switches running PVST+ multicast STP frames on a Cisco STP MC MAC address with the exception of VLAN 1. Only VLAN 1 is sympathetic to the requirements of the IEEE STP MC MAC address.
