Table 52: Enhanced Subscriber Management Accounting (description) 
Attribute ID Attribute Name Description
1 User-Name Refers to the user to be authenticated in the Access-Request. The format for 
IPoE/PPPoE hosts depends on configuration parameters pppoe-access-
method, ppp-user-name or user-name-format in the CLI context configure 
subscriber-mgmt authentication-policy <name>. The format for ARP-hosts 
is not configurable and always the host IPv4-address. The RADIUS User-
Name specified in an Access-Accept or CoA is reflected in the corresponding 
accounting messages. The attribute is omitted in authentication/accounting via 
configure subscriber-mgmt authentication-policy/radius-accounting-
policy <name> include-radius-attribute no user-name.
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 the IPv4 address of the system interface (configure 
router interface system address <address>).
The default NAS-IP-Address value can be overwritten:
ESM: configure aaa radius-server-policy <policy-name> servers source-
address <ip- address>
DSM: configure aaa isa-radius-policy <name> nas-ip-address-origin {isa-
ip|system-ip}
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-
attribute nas-port, configure subscriber-mgmt radius-accounting-policy 
<name> include-radius-attribute nas-port.
6 Service-Type The type of service the PPPoE user has requested, or the type of service to be 
provided for the PPPoE user. Optional in RADIUS-Accept and CoA. Treated 
as a session setup failure if different from Framed-User.
7 Framed-Protocol The framing to be used for framed access in case of PPPoE users. Optional in 
RADIUS-Accept and CoA. Treated as a session setup failure if different from 
PPP.
