344 Authentication, Authorization, and Accounting
The RADIUS server should be configured such that it will send the Cisco AV
Pair attribute with the “roles” value. For example:
shell:roles=router-admin
The above example attribute gives the user access to the commands
permitted by the router-admin profile.
RADIUS Change of Authorization
Dell EMC Networking N-Series switches support the Change of
Authorization Disconnect-Request and COA-Request per RFC 5176. The
Dell EMC Networking N-Series switch listens for the Disconnect-
Request/COA-Request on UDP port 3799. The Disconnect-Request/COA-
Request identifies the user session to be terminated using any or all of the
following attributes:
User-Name (IETF attribute #1)
NAS-Port (IETF attribute #5)
Framed-IP-Address (IETF attribute #8)
Acct-Session-Id (IETF attribute #44)
Calling-Station-Id (IETF attribute #31, which contains the host MAC
address)
For CLI-based sessions (Console, Telnet and SSH), the supported Session
Identification Attributes are User-Name and Framed-IP-Address.
The Calling-Station-ID must be a string of upper or lower case hexadecimal
digits in one of the following formats:
Raw notation, for example, AbCD01234567 - length 12
Dotted quad notation, for example, BADC.1010.1234 - length 14
Colon separated hex digits, for example, AB:cd:01:23:45:67 - length 17
Dash separated hex digits: 01-23-45-67-89-Ab - length 17
A RADIUS Disconnect message may also contain the Acct-Terminate-Cause
attribute (IETF #49).
The following messages from RFC 3576 are supported:
40 – Disconnect-Request
41 – Disconnect-ACK
