Point-to-point link not allowing through traffic

-- Hardware setup --

We have the following setup (IP`s abbreviated to last digits):

Side A:
Cisco C2960 (ip 184)-> Alvarion BreezeNet B100 Base Unit (BU), ip 188 - (connected to trunk port)
Side B:
Cisco C2960 (ip 187) -> Alvarion BreezeNet B100 Remote Bridge (RB) ip 189 - (connected to trunk port)

Alvarion links are connected with 100% link strength.

From side A:
Connected to VLAN 20 I can reach management interface of BU connected to trunk, no ping reply from 189 from shell, ping reply from 189 from inside management interface of BU.

From side B:
Connected to VLAN 20 I can reach management interface of RB connected to trunk, ping reply from 188 from shell and. No connection to switch on side A...

--Configuration--

Trunk ports configured using following:
switchport mode trunk
switchport trunk allowed vlan all

(All other config lines removed for the actual ports)

-- Comment --

I assume this might be a switch conf problem, but I can`t point out what`s wrong.

Any ideas?

Hi,
Try the follwoing commands in the Switch interfaces connecting to Access points-
interface GigabitEthernet0/11
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 201
 switchport trunk allowed vlan all
 switchport mode trunk
 switchport nonegotiate
Hope it works.

For some reason, the B100 link from alvarion acts as a trunk only if one end is configured as a trunk, and the other one as a hybrid.

Why? Neither Alvarion or the distributor can tell me - but it works :)
