Re: All interrface vlans down

vlans are down when there is no active interface in the vlan. Using trunk links between switches is the quickest way to get all vlans up. Don't know if this fits in your design.

Re: All interrface vlans down

could you double check eigrp config. the problem could be on your routing configuration.Ofcourse you should start troubleshooting by checking L1 and L2 issues

Re: All interrface vlans down

Keep in mind we are only human as you and not in any way supernaturally gifted;-) We really need more info to come up with a solution to your problem. Is that so hard to understand?When you think the above is sufficient info, man, then what about the following questions:

1: is the distribution switch running on layer2 or layer3? What about the core L2/L3?

2: where is the mgmt vlan located?

3: how have you set up the vtp domain(s)?

4: what is the output of: sh ip ro on the various L3 devices?

5: is the the access to mgmt vlan in any way protected by an acl?

6: many more questions might be significant but the above shoud suffice for a start.

Re: All interrface vlans down

Not sure if this is what your problem is, however if you are running a CAT/OS switch and have a MSFC within it, you may experiance an issue where all the Interface VLAN's are Down/Down. This is what happens when the trunk between the switch and MSFC do not allow the VLANs that you are trying to bring up on the MSFC. If you type SHOW TRUNK on the switch look for the trunk for the MSFC (probably 15/1 or 16/1). Look to see if your VLANs are allowed on the trunk. If not allowed then allow them. Then bring up the Interface VLAN's on tghe MSFC. They will now show Up/Up... Hope this is your issue..Good Luck...
