Hi. I have 4 SGE2010P switches in L3 stacked mode in my production environment. I am having trouble routing traffice to/from my vlans. I have successfully set this up in a test environment and have compared switch settings, but still having trouble in the production environment.
Main network:
192.168.0.0/24, DG 192.168.0.1
Vlan 1 interface on switch: 192.168.0.253/24
Vlan 22 interface on switch: 192.168.22.1/24
Vlan 23 interface on switch: 192.168.23.1/24
I have assigned port 1/g14 to Vlan 23. I have enabled DHCP Relay and Option 82. I have set DHCP interface to Vlan 23. Static routes auto-genned as shown in image below. My DHCP server is on 192.168.0.16 on Vlan 1. It has a scope for 192.168.23.0/24 to give a DG of 192.168.23.1 (Vlan 23 IP address).
I cannot get DHCP to give me an address from the .23 scope. So I tried to hard code an IP address into the client. When I did this, the switch sees the machine just fine, I can ping 192.168.0.253 (Vlan 1 IP address), but cannot ping any other IP on Vlan 1 (192.168.0.0/24)
Do I need a static route somewhere that I am missing? I didn't need to on my test network, so I am a bit stumped.
Thanks!

Jeff,
1)
Your IP interface for VLAN 1 is 192.168.0.253
In your 1st statement you say that MAIN NETWORK is using 192.168.0.0/24 with a DG of 192.168.0.1
On your device DG 192.168.0.1 you will need to add statc routes to VLAN 22 ( 192.168.22.0/24)
& 23 (192.168.23.0/24) via 192.168.0.253
2)
DHCP not working
Have you set the scopes for Vlan 22 & 23 under a superscope ?
If you have then DELETE the superscope as they are not suitable for multiple VLAN working.
Just run single scopes.
Also have a read at this link re DHCP forwarding.

It may help.
