I have a CRS328-24P-4S+ with SwOS 2.17 (latest)
I configured with VLANs as usual on my other CSS switches. I use a VLAN for management purposes, so I set this VLAN ID to 'Allow from VLAN'.
Everything worked fine till I configured the DHCP snooping on UPLINK trunk ports. These ports are used for management also.
After I set the DCHP snooping, connection lost with the switch and not able to access on ports which ticked to "trusted" in DHCP snooping section. Enable/disable add Option 82 setting is not affecting.
Seems this is another annoying SwOS bug with DHCP snooping. The community have been struggling for years witch DHCP snooping bugs in SwOS. LAG on VLAN trunk with DHCP snooping etc..
