Dell S3048-ON Configuration Manual page 179

ASDOT representation combines the ASPLAIN and ASDOT+ representations. AS numbers less than 65536 appear in integer format
(asplain); AS numbers equal to or greater than 65536 appear in the decimal format (asdot+). For example, the AS number 65526 appears
as 65526 and the AS number 65546 appears as 1.10.
Dynamic AS Number Notation Application
Dell Networking OS applies the ASN notation type change dynamically to the running-config statements.
When you apply or change an notation, the type selected is reflected immediately in the running-configuration and the show commands
(refer to the following two examples).
