Help configuring jumbo frames on CCR2004 VLANs

Traveler382 · Thu Mar 25, 2021 3:29 pm

I'm having problems finding all the required settings for enabling jumbo frames for VLANs on my CCR2004. I thought I got everything properly configured (router config below), but Winbox shows an actual MTU of 1500 for all VLAN interfaces. The bridge itself shows 9000. Ultimately what I need is all VLAN interfaces (except WAN) set to an actual MTU of 9000. What am I missing? I basically have the same VLAN config on my CRS317, and those are set to 9000.
