SUMMARY

When the script hits VLAN "monitor", it naturally fails as the template only allows digits or dashes.
Also, NVE interfaces caused issues. Included some workarounds in below fix.

FIX?
Value INTERFACE ([\w+/]+)
Value VRF (\S+)
Value STATUS (up|down)
Value IP (\d+\.\d+\.\d+\.\d+)
Value SPEED (\S+)
Value MTU (\d+)
Value VLAN (monitor|[\d+-]+)
Value TYPE (\S+)
Value MODE (routed|access|trunk|pvlan|fabric)
Value REASON (\S+((\s\w+)+)?)
Value PORTCH (\S+)
Value DESCRIPTION (\S+((\s\w+)+)?)
Value PROTOCOL (\S+)

Close, instead of adding monitor, switch the search to a \S+ to capture words and digits.
