Given that most management applications discover the SNMP interface
instance with the IP address attached to it and display the interface
description of that ifIndex only, I usually only use the logical
interface (unit) description. Unless with multi-unit interfaces, where I
document the physical remote side in physical interface level
description, and the service description on the unit.

Same goes for switches - using the unit-level description generally,
with addition physical interface description for trunk remote
system/port documentation.

Best regards,
Daniel
