4 NAS-IP-Address The identifying IP Address of the NAS requesting the Authentication or
Accounting. Included when the RADIUS server is reachable via IPv4.
The address is determined by the routing instance through which the
RADIUS server can be reached:
“Management” — The active ipv4 address in the Boot Options File (bof
address ipv4-address)
“Base” or “VPRN” — The ipv4 address of the system interface
(configure router interface system address address).
The address can be overwritten with the configured source-address
(configure aaa radius-server-policy policy-name servers source-
address ip-address).
5 NAS-Port The physical access-circuit on the NAS which is used for the
Authentication or Accounting of the user. The format of this attribute is
configurable on the NAS as a fixed 32 bit value or a parameterized 32
bit value. The parameters can be a combination of outer-vlan-id(o),
inner-vlan-id(i), slot number(s), MDA number(m), port number or lag-
id(p), ATM VPI(v) and ATM VCI(c), fixed bit values zero (0) or one (1)
but cannot exceed 32 bit. The format can be configured for following
applications: configure aaa l2tp-accounting-policy name include-
radius-attribute nas-port, configure router l2tp cisco-nas-port,
configure service vprn service-id l2tp cisco-nas-port, configure
subscriber-mgmt authentication-policy name include-radius-
