Need some advice on the outcome. Currently there is an ASA5505 managing the data network via a single subnet. Servers are plugged directly in and the switch serving the workstations is plugged in. All devices are on the 192.168.20.0 network. It is our idea that we will plug the switch into the expantion port of the UC540 and then plug from the LAN side via access port of the UC540 into the ASA. Are there any potential problems that would occur with CCA or the design?
In CCA, turn of Data subnet DHCP. On the ASA, have routes to the voice and cue subnets. On the UC500, have a default route pointing to the ASA. If you do that, you should be fine.
