What is the interface responsilbe for switch in cisco 1800? I see there FA0, FA1, FA2 ... FA9 where FA2 to FA9 is switch port, and when i try to configure then I see error message, that L2 cannot be configured or something like taht. I neet to connect two routers via this swich port. Port 9 is in VLAN 14. FA1 is configured for LAN with VALN's. FA1 is connected with HP swich and i don't have access to it. FA0 is connected to WAN modem. I configured subinterface FA1.4 and assigned it to VLAN 14 but this configuration didn't work.
Can you help me a little bit?
