Canopy SM - Flapping on Cisco switches

Hi everybody,

We have e problem with our network. For a couple of months we have a strange problem causing by Canopy SM of our clients. On some switches (Cisco 3550) it appear a lot of flapping, on receptive SM's vlans. Why is this happen? This problem happen only with SM clients not with APs or CMMs. Is that a loop connection that comes from our clients? Or a problem communications between Cisco vs Canopy.
Is there any solution for this issue? To be clear, SMs are without NAT. All equipments are in different manage-vlans, to be able to reach them in case of problems.

pls, give me any idea.

thnx

Are you using a 300SS for suppression? Also, You'd get better response in the Wisp forum: »Wireless Service Providers

Yes. We use 300SS Surge.

Can you tell me how to move this topic to the Wireless section?

What does the Ethernet Stats tab say on this SM?

We've had lots of problems with Canopy and Cisco matching up duplex on the Ethernet. Usually we end up just locking the Ethernet to 100BTFDX.

Ja, I can attest to weird probs with the 300SS. Try replacing it.

Same here. Force speed and duplex on the devices and see if your problem goes away.

do you actually have ethernet connectivity drops at the SM?
show me what the actual cisco log says, does it say the MAC is flapping between ports?
