My solution, which works for environments up to medium size, is to create multple alerts,for example
switch alerts - all
switch alerts - ignore esxi ports
swtich alerts - ignore firewall ports
switch alerts - ignore hsm ports
Normally, 'switch alerts - all' is enabled, but when maintenance is going occur on esxi hosts, we disabled 'switch alerts - all' and enable 'switch alerts - ignore esxi ports'.
This allows a bit of control without writing a script to query your ticket tracking system, and using that data to query your cabling database, and then using that data to update a generic 'link state' alert because in my opinion, telling a NOC to ignore alerts is the worst thing you can do.
