L2TP Tunnel Accounting
Page 206 7750 SR RADIUS Attributes Reference Guide
52 Acct-Input-Gigawords Indicates how many times (zero or more) the [42] Acct-Input-Octets counter
has wrapped around 2^32 in the course of delivering this service.
53 Acct-Output-
Gigawords
Indicates how many times (zero or more) the [43] Acct-Output-Octets counter
has wrapped around 2^32 in the course of delivering this service.
55 Event-Timestamp Record the time that this event occurred on the NAS, in seconds since January
1, 1970 00:00 UTC
61 NAS-Port-Type The type of the physical port of the NAS which is authenticating the user and
value automatically determined from subscriber SAP encapsulation. It can be
overruled by configuration. Included only if include-radius-attribute nas-port-
type is added per application: configure subscriber-mgmt authentication-
policy (ESM authentication), configure subscriber-mgmt radius-
accounting-policy (ESM accounting), configure aaa isa-radius-policy (LSN
accounting, WLAN-GW) and configure aaa l2tp-accounting-policy (L2TP
accounting). Checked for correctness if returned in CoA.
64 Tunnel-Type The tunneling protocol(s) to be used (in the case of a tunnel initiator) or the
tunneling protocol in use (in the case of a tunnel terminator). This attribute is
mandatory on LAC Access-Accept and needs to be L2TP. The same attribute
is included on LNS in the Access-Request and Acct-Request if the CLI
RADIUS policy include-radius-attribute tunnel-server-attrs is enabled on
7x50 LNS. For L2TP Tunnel/Link Accounting this attribute is always
included on LAC and LNS.
65 Tunnel-Medium-Type Which transport medium to use when creating a tunnel for those protocols
(such as L2TP) that can operate over multiple transports. This attribute is
mandatory on LAC Access-Accept and needs to be IP or 'IPv4.The same
attribute is included on LNS in the Access-Request and Acct-Request if the
CLI RADIUS policy include-radius-attribute tunnel-server-attrs is enabled on
7x50 LNS. For L2TP Tunnel/Link Accounting this attribute is always
included on LAC and LNS.
66 Tunnel-Client-
Endpoint
The dotted-decimal IP address of the initiator end of the tunnel. Pre-
configured values are used when attribute is omitted (configure router/
service vprn <service-id> l2tp local-address). If omitted in Access Accept
on LAC and no local-address configured, then the address is taken from the
interface with name system. This attribute is included on LNS in the Access-
Request and Acct-Request only if the CLI RADIUS policy include-radius-
attribute tunnel-server-attrs is enabled on 7x50 LNS. For L2TP Tunnel/Link
Accounting this attribute is always included on LAC and LNS as untagged.
67 Tunnel-Server-
Endpoint
The dotted-decimal IP address of the server end of the tunnel and is on the
LAC the dest-ip for all L2TP packets for that tunnel.
