ASA 5505 Configuration Questions tman 04-15-2008

I have configured an ASA 5505 for use in a branch office. I purchased
a 50-user base license. One ethernet port, eth0/7, is in vlan2
(outside) and the others are in vlan1. I want to connect one of the
inside ports to a 20-port switch just to have more ports. I do not
want to trunk vlans. It does not work. I thought I would try to
change the mode of one of the inside ports to trunk mode instead of
access mode. It says with this license I can't change it to trunk
mode.

Is there no way to do this?

Thanks

I was connecting an el cheapo Linksys switch to the ASA using a
staraight-through cable from the uplink port to an inside port on the
ASA. This did not work. A straight-through or a cross-over from a
regular port on the Linksys to an inside port on the ASA works. I
guess the uplink port on the ASA confuses the autosensing on the
ASA. :-)

Sometimes the uplink port on a device is an "either/or".

E.g.: You can use port x on the switch OR the uplink, but not both
simultaneously.

Perhaps, while connecting the uplink, the port which it is associated
with had a device connected to it.
