I have Cisco SG300-28, SG350-28, and Catalyst 2960 switches. SG350-28 and Catalyst 2960 are connected to SG300-28 via a trunk. The Bridge Priority of Cisco SG300-28 is set as 4096. However, the Catalyst 2960 switch sees it as root bridge only for VLAN 1 for all other VLANs the Catalyst 2960 sees itself as the root.
Cisco SMB series switches make you enter STP/RSTP Bridge Priority in the multiple of 4096 but apparently does not support Per-VLAN STP/RSTP. What is Cisco trying to do? Is there any new firmware which supports Per-VLAN STP/RSTP or am I missing something?
