1861 switch and F0/0 interface/VLAN config

wilson_1234_2
Level 3
Level 3

I have 1861 being used for small sites.

I have the 8 port switch configured in a vlan with an SVI and three devices pluged in.

All this is working with no problem. I can communicate from the main office via BGP to all remote sites using these 1861s.

At the moment the F0/0 interface is configured with an address in a different subnet altogether.

This will be the default gateway of a Video Phone, The device can uplink directly to the etherent port and communicate. I have tested this with a laptop.

There is never any reason for the phone traffic to communicate with anything other than the main site, and in fact would be better to isolate this traffic from getting to the other devices.

Any thoughts on what I have done and if there is a better way to do it?

This is almost an identical configuration for the one that I use at my house. I have a ROKU box that I use to stream video, and it has a dedicated VLAN. It works fine.

On your ports F0/1/x, if you are only going to have video phones attached to that port, then you'll be fine. Otherwise, if a user connects a PC into that port, your video quality may suffer. You want to make sure that you don't have anything connected to these ports for other than what they were intended.

HTH,

John
