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.
We will be purchasing used/refurbished equipment because there is no way the management will approve two new switches that could run 8-10K. You said, "You can also have a voice Vlan and a data Vlan on the same port." Well, that is exactly what we will need to do. So, by choosing trunking, I will be able to achieve that?
In short, the VoIP device you are planning to use, it's the deciding factor on what kind of configuration must be done at the switch side.
Another word of advice, VoIP is an emerging technology. Purchasing outdated equipment is not recommended. If you encounter any bugs on the switch side, you will be in a tough situation as the equipment will be out of warranty. Something to consider and suggest to upper-management.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
