interface MTU mismatch

Find connected interfaces that have mismatched MTU settings​

The following check iterates through all devices and interfaces, and the links from those interfaces. Then it looks up each connected interface with a second iteration, and then filters to include just those pairs of connected interfaces that have MTU values that are mismatched.

foreach d1 in network.devices
foreach i1 in d1.interfaces
foreach link in i1.links
foreach d2 in network.devices
where d2.name == link.deviceName
foreach i2 in d2.interfaces
where i2.name == link.ifaceName
where isPresent(i1.mtu) && isPresent(i2.mtu)
select {
  device1: d1.name,
  iface1: i1.name,
  mtu1: i1.mtu,
  device2: d2.name,
  iface2: i2.name,
  mtu2: i2.mtu,
  violation: i1.mtu != i2.mtu
}
