Hi everybody,
a quick question: if i have a trunk port with different VLANs and I connect this port to a routed port with assigned IP on a subnet belonging to one of those VLANs, will this port come up straight away?
Thanks.

It will if the native vlan of the trunk is the correct vlan that the ip address is from.

Hello,
So if I understand the problem right, the scenario should be something like this
Trunkport L3port
Switch1--------------------------------Switch2
int vlanx 10.10.10.2 255.255.255.0
10.10.10.1
255.255.255.0
- The trunkport on Switch1 which allows multiple vlans on it is connected to an L3port configured with an IP address in the same subnet as of vlan x
- Since dot1q tags frames, a device/port that doesnt 'understand' the tag won't be able to read the frame
- To make this work, we can either set the native vlan on the trunk to vlan x (so frames sent are untagged) OR we can set the port to an access port in vlan x
Hope this helps.
