we have a problem with all the CRS112 in our network.
They generally work but, sometimes, they stop forwarding all VLANS and wewe have to reboot them.
Can it be a MTU problem? LTU is set to 1500 and L2 MTU to 1588
I post here the config, the VLAN 255 is for management, other VLANS are for users:
Code: Select all
#RouterOS 6.44.5
# software id = PK4Y-FSHB
#
# model = CRS112-8P-4S
