27 Session-Timeout Sets the maximum number of seconds of service to be provided to the user
(IPoEv4/PPPoE) before termination of the session. Attribute equals to [26-
6527-160] Alc-Relative-Session-Timeout when received in Access-Accept
since current session time portion is than zero. Value zero sets the session-
timeout to infinite (no session-timeout). The attribute is CoA Nack'd if its value
is smaller than the current-session time. Simultaneous received [27] Session-
Timeout and [26-6527-160] Alc-Relative-Session-Timeout are treated as a error
condition (setup failure if received via Access-Accept and Nack'd if received
via CoA). For IPoEv4 radius proxy and CoA create-host scenarios, [27]
Session-Timeout is interpreted as lease-time instead of session-time if [26-
6527-174] Alc-Lease-Time is omitted.
28 Idle-Timeout Sets the maximum number of consecutive seconds of idle connection allowed to
the user before termination of the session (IPoE/PPPoE) or a connectivity check
is triggered (IPoE). Values outside the allowed Limits are accepted but rounded
to these boundaries. A value of zero is treated as an infinite idle-timeout. The
idle-timeout handling on the node is implemented via category-maps
(configure subscriber-mgmt category-map <category-map-name> and
configure subscriber-mgmt sla-profile <sla-profile-name> category-map
<category-map-name>).
30 Called-Station-Id Allows the NAS to send in an Access Request and/or Accounting Request
information with respect to the user called. Attribute is omitted in
authentication/accounting via: configure subscriber-mgmt authentication-
policy/radius-accounting-policy <name> include-radius-attribute no called-
station-id.
Supported applications:
• LNS: the content is the string passed in the [21] Called Number AVP of the
L2TP ICRQ message.
• EAP authentication on WLAN Gateway: transparently forwarded as
received in EAP authentication or accounting messages from the AP
31 Calling-Station-Id Allows the NAS to send unique information identifying the user who requested
the service. This format is driven by configuration (configure subscriber-
mgmt authentication-policy/radius-accounting-policy <name> include-
radius-attribute calling-station-id <llid|mac|remote-id|sap-id|sap-string>).
The LLID (logical link identifier) is the mapping from a physical to logical
identification of a subscriber line and supplied by a RADIUS llid-server. The
sap-string maps to configure service <service-id> subscriber-interface <ip-
int-name> group-interface <ip-int-name> sap <sap-id> calling-station-id
<sap-string>. A [31] Calling-Station-Id attribute value longer than the allowed
maximum is treated as a setup failure. The attribute is omitted in authentication/
accounting via configure subscriber-mgmt authentication-policy/radius-
accounting-policy <name> include-radius-attribute no calling-station-id.
