I have inherited a complicated LAN that I'm trying to resolve some issues in.
Here is the situation:
The switch was configured with 4 VLANS and DHCP. The VLANS are listed below.
DHCP assigns ip addresses to devices plugged into the switch according to the VLAN ID, for example 192.168.36.21 and above. Same for 37, 39 and 42. I need to reprogram the DNS entry in DHCP. We removing a very small netgear router/firewall and replacing it with a Sonciwall NSA 2400. The environment is mostly Apple PC's and webcams. There is no internal DNS server, we are going to use the ISP routers IP address for the DNS entry, instead of the internal LAN device.
I have next to zero experience with configuring Catalyst switches, can someone help me understand how to reprogram this to have the settings I need?
