Disclaimer: We are mostly server guys here and know enough switching to be dangerous. We know very little about spanning tree, etc.
We're implementing our phase 1 of our Enterasys replacement and have been installing B5 stacks in all of our headquarter IDFs. They are connecting back to a Cisco 6509 (Sup 2). We just started having problems where the 6509 would err-disable the LACP lag between the 6509 and the IDFs. The lag is set for trunking. In the terminal of the 6509 it shows channel mismatch error. We spoke with GTAC and they said something about the B5 stacks not participating in spanning tree and the 6509 doesn't know what to do so it disables it. Also, some of our IDFs have another Cisco switch farther down... example: 6509 --> B5 Stack --> Cisco 3750. The 3750 is also trunking. These setups seem to be the ones with problems. GTAC suggested possibly moving from PVST to RSTP so all of our spanning-tree is the same. Unfortunately I'm not exactly sure how we would do that or if that's the solution for us. Anyone have experience with this type of setup and did you have problems? Thanks.
