Notes:
- Token names vary between Cisco IOS, IOS‑XE, NX‑OS and documentation; many commands accept multiple formats (e.g., A.B.C.D or A.B.C.D/M).
- Numeric ranges differ by command (VLANs, ports, ASNs). The table gives common ranges; refer to command help (?) for exact per-command ranges.
- WORD is the generic token for a single text token without spaces; STRING allows spaces.
