On a Catalyst 6500 or 5505 you can force an SVI Interface to always be in an Up state with an autostate command, However on a Cat 3550 EMI I cant seem to make this work. What I am trying to do is set up trunks and route several vlans using SVI Interfaces. What seems to be happening is when I set up the approprate SVI and send the vlan through the trunk to an end switch the SVI will not go to an up state. When I assign the vlan to a port then plug the port in the SVI will come up. Does anyone have any ideas as to how I can make the SVI Interface come up without assigning the vlan to a port and using the port as a static assigment.
If the interface is in a "working" trunk and allowed across that trunk then the SVI should be up . I would verify your config on both sides of the trunk . Are you creating the layer 2 vlan interfaces also when you do this ?
