CatOS - Multiple DHCP Clients

Is it possible to use CatOS to make each port act as a network card would in a normal machine requesting an IP address via DHCP? Going one step further would it be possible to have multiple VLANs on each port demonstrating the same behavior?

Unfortunately, I believe what you are trying to accomplish is not possible in CatOS. You can have the sc0 interface dynamically obtain an IP via DHCP, but unlike IOS, you cannot have individual blade ports obtain IP's via DHCP.

Probably. Although I've never tried it.  Also, it's kind of a kludgy approach.

First, the IP address won't be assigned to the physical port, but to the SVI associated with the port.

So basically you would create a VLAN and assign the port in question to that VLAN. Then get into the RSFC (or RSM) and create an SVI for that VLAN. Finally, assign the IP address to the SVI using the dhcp variable "ip address dhcp". You may need to upgrade to the latest avaiable IOS version for the RSFC.  And like I said before, I've never tried this so it's possible the dhcp address function may not even be available for the RSFC.

Going one step further would it be possible to have multiple VLANs on each port demonstrating the same behavior?
Sure. You would simply create a separate VLAN for each port you wanted to do this with.
