Hi,
I have a question about a Cisco 892FSP router that I am trying to configure. The 892 has two WAN ports G8 and G9 along with seven LAN ports G0 to G7. It seems that the factory default configures the WAN ports L3 and the LAN ports to L2.
- I tried to use the “no switchport” on the LAN ports to convert them to L3, but the switch will not accept this command as is and reports it as an incomplete command. I discovered the answer to this in another post in the support community - that all the LAN ports are hardwired to L2.
- So, then I tried to get around this issue by configuring a VLAN and assigning a LAN port to it. Now here’s a curious thing: I used the same configuration (which appears at the end of this posting) in Packet Tracer, and it works fine there; however, it does not work on the router. I also get some strange responses from the router. I installed the Cisco Configuration Express Manager on the router. In the troubleshooting section, I can ping to the internet from the WAN port. When I connect to the router through the LAN port belonging to the VLAN using Express Manager, I can ping the internet from the VLAN; however, if I drop down to the DOS command line on the PC, I can only ping the LAN and WAN ports, but not anything outside of the router. I’m pretty sure the solution is simple and staring at me in the face, so if someone would be so kind and look at my configuration and tell me what kind of stupid thing I forgot to configure, I’d appreciate it.
