We are adding a 4th switch to our network. Not sure how best to configure.
Currently (see attached (new in red)) we have 3 connected switches:
HP 2910 L3 as core with two older v1910 and 3com 2952 switches connected via cat5. The core switch routes traffic out to firewall.
The 2910 also has two vlans configured for data and voice. The older switches are data only.
The new 4th switch will be in another office (c10-20m run away) and is a 2910al POE also. We need to hook up poe phones here and desktops on vlans 20 and 1 respectively.
Main questions are:
- Do we need two cable runs from the main 3 switches to the 4th? i..e switch 1 to 4 and switch 3 to 4 (chain mode instead of looped?)
- If two, can we mix the connections used to connect the switches i.e. fibre and cat5 or do they need to be the same throughout the switches e.g. cat5 only?
And if two connections do they have to be routing between the vlans e.g. vlan1 connected to vlan1 on switch 1 and 4 and vlan20 between switch 1 and 4? Or does iprouting resolve this?
