I have an Sonicwall nsa 3600 with port 12-15 in a port shield group with a couple vlans. The 1gb fiber ports are going to a Meraki ms420 fiber aggregation switch. According to Meraki dashboard, 3 if the 4 ports are discarding stp.
Should the fiber ports on the Meraki be in a link aggregation ? Why is this happening. Have I miss-configured something on the nsa ?
