Hello community,
im having an issue with DHCP, between a trunk from a matix N7 to a C3 switch over a FO link, using VLAN 1, 7, 10 and 11
Basically, everything works when tested directly in the N7. I can get an IP to any machine over DHCP on any VLAN and in any network i desire.
Even when configuring a "trunk" port in another switch with the same exact configuration and plugging it directly to the N7, everything works properly.
But once i try to get an IP in a network inside a given tagged VLAN ( 1,10 and 11) that crosses the FO link from the N7 over to the C3, im unable to get anything else than the one that is given by the untagged VLAN (7).
I contacted the ISP for that FO link but they assured me that the link is a pure Layer2 and anything is accepted inside it. So im lost here. Im almost sure the issue is with the FO link not being able to pass any tagged traffic, but im a bit green with Enterasys so i want to be sure.
heres my config. any help would be great.
