We are putting in a new Cisco ASA 5520 to replace our Pix 515. We have Cisco managed switches (I think Cisco 3750 but not sure ). We have Cisco VOIP phones on the same network that the computers are on.
We would like to setup VLans to separate the traffic in order to improve the network performance. The cisco switches are Gigabit switches.
Is the only way to setup VLans thought port VLans or can we do it any other way. The reason is that we have one cable going into the phones and then the phones have a switch port that goes to the workstations. Therefore we can not do port VLans.
FYI, I am not familiar with VLans and am not sure how they work. Do you some how login to the switch and do it.
