This one's got me banging my head against a wall... likely a simple answer, but I've tried everything I know. I heard the internet's a smart place. :)
Have an SG300-28MPP connected to a clients' Catalyst (unsure of model, but it's recent). Have LAG1 (ports 11-12) set up to pass VLAN 75; works great. Port 25 on the SG300 is configured as a trunk, with VLANs 72 and 73 tagged.
Client's switch is configured with 75 tagged on the LAG, 72 and 73 tagged on the single-link trunk. No LACP on the LAG.
Something has changed on my end that causes port 25 to pass no traffic on either VLAN. (Within the last 24 hours I've been resolving a multicast issue... can't figure out what I may have done there that would affect this.)
Config appears below, with unrelated ports and security stuff removed.
Many thanks for any wisdom you can lend!

native vlan mismatcherror. This is really cosmetic, and it is a pain because it keeps popping up, but it doesn't actually interfere with the traffic.
