Steve, Thanks, makes sense. I just don't see why I have to effectively waste an extra IP address to get my connection established. Boris.

We have lots of servers with a similar setup (i.e. tagged vlans and no ip on eth0) and this works just fine. What is the actual vlan configuration on your switchport?

Do you need the whole configuration? On the switch end, we have the relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN. Seems - and acts - like a legitimate setup and works fine, except for this particular instance. Thanks. Boris.
