VLAN 1 interface is up, protocol is down on 2950 switch
I got three 2950sx-24 switches gigastacked together(through WS-3500-xl module) and uplinked to a 6509 switch through a WS-G5484 fiber module. I configured the management interface in each of 2950 as following:
ip address 10.1.1.11 (10.1.1.12 and 10.1.1.13 separately) 255.255.255.0
When I do a "show int vlan1" in 2950-I and 2950-II,I got:
int vlan1 is up, protocol is down
only in third 2950, I got:
int vlan1 is up, protocol is up
but even in this 2950, I can't ping the default gateway 10.1.1.1 although I can ping its own ip address.
I tried to shutdown and "no shutdown" in interface vlan1 of those switches several times, but it remains the same.

Thanks for your answer.
But I don't have any other vlans configured on the other switches.
To be clear, all ports of three switches have been assigned to vlan 11. (Gigastack port belongs to vlan 11 as well, not working in trunk mode). Does that mean "interface vlan 11" need to be configured instead of "interface vlan 1" ?
