What is the output of 'vif status vif_fas02'? What is the output on the cisco switch of 'sh interface status po10' (iirc)? 3750's have often need to have etherchannel mode forced to "on" instead of desirable.
My memory fails me, but setting vlans on Po interfaces might need to be done on the physical interfaces... You might try to do 'sh trunk' and see which vlans are active and forwarding as well.
All that I can think of at the moment...haven't been a net admin for a few years now. Hope it helps.
When we created vif initially, it was on a single physical port only (e0b) & we chose IP-based load balancing. Actually, all addresses on all three VLANs were accessible at that point.Then we added the second physical NIC (e0a) to the vif. All looked fine in the GUI, yet vif status showed that e0a was in a pending state.
So my thinking is: IP-based load balancing means VLAN 2 was pushed via e0b, whilst any additional VLAN was supposed to go via e0a - but the interface wasn't properly up, hence it didn't work.
I just tested it again by vlan delete & vlan add and all works 100% fine.
