26-6527-132 Alc-Access-Loop-
Rate-Down
The actual downstream rate (coded in kbits per second) of a PPPoE subscriber's
synchronized DSL link and competes with the value received from alternative
sources (dsl-forum tags, ludb, ancp). Values outside the Limits are treated as
setup failures. Attribute is silently ignored for None-MLPPP sessions or IPoE
sessions.
26-6527-133 Alc-Access-Loop-
Encap-Offset
The last mile encapsulation representing the subscribers DSL access loop
encapsulation and when returned in RADIUS-Accept (PTA or LAC) is taken
into account for ALE adjust (last mile aware shaping) but not reflected in [26-
3561-144] Access-Loop-Encapsulation (access-loop-options) send to
Accounting. For LAC this attributes maps to LTP AVP [3561-144] Access-
Loop-Encapsulation.
26-6527-135 Alc-PPP-Force-
IPv6CP
Forces IPv6CP negotiation in conditions were the Access-Accept does not
return any ipv6 related attributes (v6 pool, v6 prefix, v6 address,
dnsv6).Without these ipv6 related attributes the NAS has no way to detect that
this is a dual-stack pppoe user and therefore it will not start IPv6CP unless this
attribute is returned in the Access-Accept. Values 1 triggers ipv6cp and value 0
is treated the same as not sending the attribute. Values different than the Limits
are treated as setup failures.
26-6527-136 Alc-Onetime-Http-
Redirection-Filter-
Id
The pre-configured ipv4 filter with http-redirection rules. Via this host specific
filter only the first HTTP request from the host will be redirected to a
configured URL with specified parameters. There is no HTTP redirection for
subsequent HTTP requests. Useful in cases where service providers need to
push a web page of advertisement/announcements to broadband users.
26-6527-160 Alc-Relative-
Session-Timeout
Sets or resets the IPoE/PPPoE session timeout to a relative value (current
session time + newly received Alc-Relative-Session-Timeout). Attribute equals
to [27] Session-Timeout if received in Access-Accept since current session time
portion is than zero. Value zero sets/resets the session-timeout to infinite (no
session-timeout). Simultaneous received [27] Session-Timeout and [26-6527-
160] Alc-Relative-Session-Timeout are treated as a setup failure (setup failure if
received in Access-Accept and ignored if received in CoA).
26-6527-161 Alc-Delegated-
IPv6-Prefix-
Length
Defines the IA-PD length information [DPL] and only applicable together with
[26-6527-131] Alc-Delegated-IPv6-Pool (silently ignored if received in
RADIUS Accept without Alc-Delegated-IPv6-Pool). Maps to DHCPv6 vendor-
option[17] ,sub-option[3] pfx-len. The [26-6527-161] Alc-Delegated-IPv6-
Prefix-Length has priority over other possible sources of DPL. (As a fixed or
variable DPL under configure service ies/vprn <service-id> subscriber-
interface <ip-int-name> ipv6 delegated-prefix-length or on the dhcpv6 server
configure router dhcp6 local-dhcp-server <server-name pool <pool-name>
delegated-prefix-length). DPL values outside the limits are treated as setup
failures.
