Help with ICX 7150s and stp deployment

[johan_castro_a]

Hey guys. I'm about to replace our current network switches (HPs) with brocade icx 7150 and I need your help.

Here is my scenario:

ICX 6430-48 (stack): this is the core or distribution switch (this is going to stay in place until I replace the access switches)

Port 2/1/33 is tagged in all vlans (2,3,5,7). (This goes to one of the new ICX 7150)

I configured port 1/1/24 on the new ICX 7150 as a tagged port on vlans 3,5,7,10 and untagged on vlan2. When I connected the cable port 2/1/33 on the 6430 changed its status to Blocking. I set spanning-tree 802-1w for all vlans on the icx 7150.

I believe I'm missing something in the stp configuration. I will be connecting more 7150s to the 6430, and the 7150's will connect to other 7150s so I have to make sure I understand how this work before replacing the other switches. I read something about spanning-tree 802-1w admin-p2pt-mac but I'm not sure if that is what I need.

Thanks in advance.

Thank you! I'll have to keep trying, I haven't made any progress. The vlan tagging matches, I added the admin-pt2pt-mac to the uplink port, but I found that if I connect the cable that goes from the 6430 to the ICX 7150 the uplink port is down, it's like if the cable was not plugged in, however the same cable works fine when connected to an intellinet switch.

Out of the box I had the same issue with HP switches. I think ruckus implements spanning-tree at different level. The way I would get it running quickly was typing this at the global config:

spanning-tree single

In your case, you can try:

spanning-tree single 802-1w

I didn't need to configure anything else and they would start to cooperate.

Thanks everybody. I found the problem, the link between the core switch and the new icx 7150 runs on a cat5 cable. I adjusted the speed on the 1/2/1 to 100Mbps and it began to transmit. It seems the auto setting was not making any difference.
