The subscriber's actual one-way downstream interleaving delay in
milliseconds and maps to values received during PPPoE discovery (tag
0x0105) or DHCP (opt-82). Attribute is included/excluded based on
configure subscriber-mgmt authentication-policy/radius-accounting-
policy <name> include-radius-attribute access-loop-options.
The last mile encapsulation used by the subscriber on the DSL access loop and
maps to values received during PPPoE discovery Tags (tag 0x0105) or DHCP
Tags (opt-82). Attribute is included/excluded in RADIUS/Accounting-
Request based on configure subscriber-mgmt authentication-policy/
radius-accounting-policy <name> include-radius-attribute access-loop-
options. Last mile encapsulation information can be used to adjust
automatically the egress aggregate rate for this subscriber. Pre-configured
encapsulation types are used if PPP/IPoE access loop information (tags) is not
available (configure subscriber-mgmt sub-profile <subscriber-profile-
name> egress encap-offset <type> or configure subscriber-mgmt local-
user-db <local-user-db-name> ppp host access-loop encap-offset <type>).
[26-6527-133] Alc-Access-Loop-Encap-Offset when returned in Access-
Accept is taken into account (overrules received tags and pre-configured
encapsulation types) for ALE adjust (last mile aware shaping) but is not
reflected in access-loop-options send to RADIUS. Alc-Access-Loop-Encap
from ANCP are currently not taken into account for ALE adjust.
The presence of this Attribute indicates that the IWF has been performed with
respect to the subscriber's session. IWF is utilized to enable the carriage of
PPP over ATM (PPPoA) traffic over PPPoE. The Access Node inserts the
PPPoE Tag 0x0105, vendor-id 0x0de9 with sub-option code 0xFE, length
field is set to 0x00 into the PPPoE Discovery packets when it is performing an
IWF functionality. Attribute is included/excluded based on configure
subscriber-mgmt authentication-policy/radius-accounting-policy <name>
include-radius-attribute access-loop-options.
A subscriber is a collection of subscriber-hosts (typically represented by IP-
MAC combination) and is uniquely identified by a subscriber string.
Subscriber-hosts queues/policers belonging to the same subscriber (residing
on the same forwarding complex) can be treated under one aggregate
scheduling QoS mechanism. Fallback to pre-configured values if attribute is
omitted. Attribute values longer than the allowed string value are treated as
setup failures. Can be used as key in CoA and Disconnect Message. Attribute
is omitted in accounting via configure subscriber-mgmt radius-accounting-
policy <name> include-radius-attribute no subscriber-id.
For DSM accounting sessions the Alc-Subsc-ID-Str reflects the UE MAC
address.
