I am really frustrated trying to setup a VLAN on a Cisco 1721 router. I have tried so many times by myself but I can’t seem to find what to do. The only type of interfaces that are listed in it are the Ethernet and the fast ethernet interface. I am not very much familiar with all these networking stuff. I have just learnt to change IOS with ROMmon. Please help me in the direction so that I can setup my own VLAN with this router.
