What does this error and how can I fix?
This isn't necessarily a misconfiguration, but likely is.
LLDP carries primary vlan id in one of its attributes to help switches identify mismatches like this.
We have a number of cases were VLAN ids are only locally significant in our equipment and on completely untagged ports, with lldp enabled, the procurves will log these messages periodically because the ports have different VLAN ids on the two switches. It doesn't matter, though because the vlan id numbers are only locally significant on each switch. I wish I could turn off this message in these situations, but alas, I'm stuck with the noise.
In the typical case, where VLAN ids are more than just locally significant, this likely does represent a misconfiguration where traffic could jump from one VLAN to another if the primary VLAN on a port is sent untagged (while other VLANs are tagged).
I observed this behaviour when I connected an (A-Series) HP 5800 to a procurve 5400 with a tagged interface carrying 3 VLANs. Is this a tagged Port? One way to solve it is to transmit one of the VLANs without Tag. PVID on both sides needs to be the same in this case. If it is untagged, PVID must match anyways.
If you do not want to transmit any untagged VLAN (as I did) you can turn out the log message on the procurve with the command: setmib 184.108.40.206.220.127.116.11.18.104.22.1688 –i 1
