Previously, I brought you the idea of interVLAN routing on CISCO. Less is said about Extreme Networks but today I actually worked with a Summit 450 switch and it was fairly easy as well. The commands are a bit different but overall it wasn't anything too hard. Since I can't remember all the commands off hand, I'll just try to talk about what I remember
Firstly, configuring a vlan goes like
configure vlan "VLAN2" add ports 1 - 24 untagged
configure vlan "VLAN2" ip-address 10.0.2.1 255.255.255.0
configure vlan "VLAN3" add ports 25 - 48 untagged
configure vlan "VLAN3" ip-address 10.0.3.1 255.255.255.0
enable ipforwarding "VLAN2"
enable ipforwarding "VLAN3"
DHCP Relay goes something like this:
configure bootprelay add 10.0.10.2 #This points to your superscope DHCP Server
#Also make sure to create route so DHCP knows which gateway to pass through to send back the information
Don't want DHCP relay? Instead you can do DHCP server on the switch itself using something like this
configure dhcp address-ip-range 10.0.2.1 - 10.0.2.254 #THIS IS WRONG SOMEWHERE, BUT THAT'S ESSENTIALLY HOW THE COMMAND GOES
Sorry, some of the commands may be wrong because I'm trying to remember from memory with only 1 day experience
