Vlan configuration issues

Vlan configuration issues

I'm working on extreme summit x450 with exos 15.3.1.4. I am playing around with vlans and am having some issues. Here is my vlan configuration:

configure vlan default delete ports all
configure vr VR-Default delete ports 1:1-48, 2:1-48, 3:1-24
configure vr VR-Default add ports 1:1-48, 2:1-48, 3:1-24
configure vlan default delete ports 1:1-48, 2:1-48, 3:1-24
create vlan "Data"
configure vlan Data tag 1
configure vlan Default tag 3000
create vlan "test"
configure vlan test tag 10
create vlan "Voice"
configure vlan Voice tag 100
configure vlan Data add ports 1:3-48, 2:1-48, 3:1-3, 3:5-24 untagged
configure vlan test add ports 1:48 tagged
configure vlan test add ports 3:4 untagged
configure vlan Voice add ports 1:3-48, 2:1-48 tagged
configure vlan Voice add ports 1:1-2 untagged
configure vlan Voice ipaddress 192.168.112.3 255.255.255.0
enable ipforwarding vlan Voice
configure vlan Data ipaddress 172.24.112.27 255.255.254.0
enable ipforwarding vlan Data
configure vlan test ipaddress 172.24.108.3 255.255.254.0
enable ipforwarding vlan test
configure ports 1:48 monitor vlan test
configure ports 3:4 monitor vlan test

At the other end of port 3:4 is a fortigate router with 172.24.108.1/23. We have a dhcp server at 172.24.112.18. If I ping 172.24.108.1 from 172.24.108.3 it works. If I ping 172.24.112.18 from 172.24.108.3 it fails. I can ping it from 172.24.112.27 and it works correctly. I'm not sure where else to look to try and get this working. Ultimately I want to have DHCP handing out 172.24.108 addresses.

oh, 172.24.112.251

No, what default gateway address is set in the DHCP server = IP 172.24.112.18

network diagram please

Sadly, I don't know the best way to give you a network diagram which isn't super confusing.

Hi Jaren

Do you have a gateway configured for that 172.24.112.x network?

Thanks
