I am trying to get my head around VLAN config. I have a load of Netgear GS728TP switches accross my site, and I'm trying to get some devices moved to alternative VLANs because I have exhausted the /24 network pool assigned currently.
I have got VLAN trunking working between switches, so my Visitor WIFI VLAN (50) is now able to have an ADSL router plugged into one switch, and on other swithes connected via trunk links there are APs putting clients onto VLAN 50 - they are able to get their IP address from DHCP on the ADSL router which is what I needed.
Now I am trying to move a bunch of about 30 IP cameras to VLAN 20. I need to be able to route between the IP cameras, and the NVR device which will stay on VLAN1 (well, it could move to VLAN20 once the routing is working..)
What I have done so far, is decide on 1 switch as my "master" - it's a GS752TP. I have setup an IP address of 192.168.20.1 on VLAN20. What I can't do, is setup an IP address of 192.168.16.1 on VLAN1, as it says that the IP address interface is duplicated.
In the ARP table of my master switch, I can see the single IP camera that I've addressed as 192.168.20.10 and configured to be on VLAN20 - but I cannot ping it from either the master switch, or the one that it's plugged into - should I be able to?
Many Thanks Mark
