I have a 4-port switch on my 2811. I assign each port for a different vlan and it 's worked great until today when I did some thing wrong but I do not know what it really is :-(

Now, the output of "sh ip int bri" shows all my VLANs are "status UP" but "protocol down".

All the corresponding interface fe 0/0/0 - 0/0/3 show both status and protocol up.

Thanks for your advice,

I found it. The vlan database, for some reason, lost the definition of those VLAN. After adding the vlan N to the database, all are working fine now.
