Vlan setup on Linksys / Cisco
Posted on 2009-07-10
I just purchased a SLM224G Linksys switch by Cisco.
is a 24+2 Gb
My setup has to be the following:
Ports 1-12 plus G1 are on the same Vlan (Vlan 10 Data)
Ports 13-24 plus G2 are on the same Vlan (Vlan 20 Voice)
My firewall provides two outputs - one in G1 and one in G2
Each one has a DHCP server enabled - one generates 192.168.5.x , the other one generates 192.168.25.x (this range will be used for the VoIP phones)
Looks pretty straight forward - however:
Every port on the switch get IP's from 192.168.5.x, regardless of what Vlan or port is.If I shut down DHCP on VLAN 10 (G1) I will get IP's in the range 192.168.25.x on all teh ports regardless of location or Vlan
It seem that there is a link between Vlans and that could be that all the ports are part of Vlan 1 - default on Cisco. Right now the ports 1-12 plus G1 are part of Vlan1 and 10 , and Ports 13-24 plus G2 are part of Vlan 1 and 20 ....
How can I solve the problem so I have two separate networks - independent of eachother.
