OptionaldefaultsHuman-facing device handle: the identity= comment lookup key (mirroring
RouterOS /system/identity), falling back to the matched record's target
when the comment carries no identity=. Deliberately may repeat across
records.
OptionalmacThe record's MAC, for L2 transports (mac-telnet): the mac= comment lookup
key, or the target itself when that is a MAC. Lets --via mac-telnet
address a device resolved by identity=/ip= whose target is not a MAC.
Resolved target string from the CDB record (host / IP / base URL).
Fallback credentials from the reserved
__default__record, when present. resolveAuth fills a field from here only when the per-call args, env, and the matched device record all leave it unset (constitution: identity and CDB,__default__). Empty strings are treated as unset.
