difference between 2 config

[MikaelBoyer]

Hello everyone

i'm on intervention and i have a issu with two 2530-48 ports

one work : each vlan casn access internet throught my firewall (this device is also configured to be a DHCP relay)

the other, don't. I simply cannot obtain a dhcp. Even if i configure manually an IP adress, i just dont go anywhere, ping cannot find target etc.

Here the two config, if someone can tell me where i'm wrong, i'll be very thankful :

Please provide a basic and clear topology map (with represented Switch 1, Switch 2 and Firewall and all their relevant interconnections), for any interconnection provide the output of show vlan port x detail where x is the interface id used on both ends (e.g. show vlan port 48 detail on Switch 1 port 48 and the very same for Switch 2...because it looks like you have them interconnected together exactly via their respective ports 48).
