Need to Create Custom Report for vlan mismatches/ errors from syslog server???
Can/ will you assist???
go to NEW report and select SYSLOG then add the Field for MESSAGE and make a filter on Messages 'contains' (whatever is in the body of that syslog message) maybe - 'vlan mismatch' ..etc.
or else make a filter on Messages for 'starts with' something like 'vlan mismatch'.
I have attached a screen shot of what I use for mine.
