The subscriber's maximum one-way downstream interleaving delay in
milliseconds, as configured by the operator 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 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.
