I'm not sure I can do this.
This 2621's FE port connects directly to a Cisco Aironet 350 wireless access point. That's the only thing to which it connects. The sole function of this FE port is to provide connectivity to the AP.
The AP serves several small workgroups, each of which has a non-Cisco bridge-style client device - essentially a box with an antenna on one side and an Ethernet port on the other. Each workgroup uses a different 172.xx.0.0 subnet... 172.16.1.0 for the first group, 172.16.2.0 for the second group, and so on. The total number of actual devices is small so the single AP can easily support them, but it's important to keep them on separate subnets.
I've been simply adding each workgroup's gateway IP as a secondary IP address on the 2621's FE port, and that's been working perfectly. But I believe the max number of secondary IP's per physical port is six. The 2600 supports far more than six subinterfaces, so this provides for expansion beyond six subnets.
As I understand it, 802.1Q is really just an encapsulation protocol. It requires a corresponding device on the "other end" of the wire. That's not the situation here - I'm not running VLAN's, I just need to logically access more than six subnets from a single FE port.
Any recommendations gratefully accepted. Thanks!
