IP subnets on 3324
Hello,
I was told you can only assign 4 subnets on a 3324. I found this out after I already had it installed, which was kinda disappointing. This is my only switch in a co-location rack, and I have it as 2 Vlans, which takes up 2 subnets already. I would like to be able to have more than 4 subnets pointing to my servers, is there a way around this?
Thanks,
Stefan

The 3324 is a layer-2 switch, it has no routing capability. The four IP addresses are simply for management of the switch and have no bearing on the actual traffic through the unit.
You can have up to 250 different VLANs configured, using any VLAN numbers between 2-4096.
Since IP traffic is Layer-3 based, you can have as many subnets as you like pass through the switch, but most people map a subnet to a VLAN, meaning up to 250 subnets.

Greg,
I have a Cisco router. My question arose because when I was setting it up it was telling me something like an address table overflow when i tried to assign more than 4 ip blocks.
Currently I have a /24, which I have split between 2 servers on vlan1 (/25 on e1-8,e13-24,g1-2), and 2 servers on another (/29 on e9-12).
I would like to add IP's from completely different IP blocks to vlan1, as many as 6 or 7. If I try to assign more addresses or subnets via the CLI, I receive that error I mentioned above. When I told this to tech support they told me I could only assign 4 IP/Subnets. Is there some other way to do this?
Thanks,
Stefan
