I recently read in a CCNA book that you can only configure VLAN's one port at a time. There is no command available with older switches, like a 1900 series, that lets you assign more than one port to a VLAN at a time. I am a little confused by this. In our situation, we need to set up VOIP. The technical specs at this point seem to suggest that the only way we can do this is to purchase a 3548 XLFETH Cisco and assign VLAN's to the switch. One VLAN will be the VOIP and the other will be for the pc (data).
What would the basic commands be to allow each port to have two VLAN's on it? And how would I allocate bandwidth? The VOIP provider said that it "only" consumes about 30 Mbs, but I don't know if that is correct.
