VLAN line status on link failure

Hi,

I have a problem between pair of cat 6509 and a 3750 stack

The 6509 are linked to my core and have a line to my access layer 3750. When my physical link goes down on one of the 6509, the vlan interface are still up, blackhole-ing half of my traffic. The vlan are only present on this link.(not on any trunk)

Re: VLAN line status on link failure

Hi,

More info, there is no STP running on the vlan but the L3 is up. My bet is L2 and L3 sync is not working properly. Any advises?
