26-6527-102 Alc-ToServer-
Dhcp-Options
Send to RADIUS all DHCPv4 options received in a DHCPv4 message
triggering authentication. The dhcpv4 options are concatenated in the attribute
up to maximum length per attribute (see limits). If more space is needed, an
additional attribute is included. If the total dhcp options space requires more
than the total maximum length (see limits), then no attributes are included.
(configure subscriber-mgmt authentication-policy <name> include-radius-
attribute dhcp-options, configure aaa isa-radius-policy <name> auth-
include-attributes dhcp-options).
26-6527-103 Alc-ToClient-
Dhcp-Options
Copy the content of the attribute value in dhcpv4 options for dhcpv4 messages
towards the client. It is not required to send each option in a different VSA;
concatenation is allowed. Only the attributes within the defined limits (see
limits) are parsed and stored; the remaining attributes are silently ignored.
26-6527-105 Alc-Ipv6-Primary-
Dns
The IPv6 address of the primary DNSv6 server for this subscribers connection
and maps to DNS Recursive Name Server option 23 (RFC 3646) in DHCPv6.
This attribute is an alternative for [26-4874-47] ERX-Ipv6-Primary-Dns.
Applicable in proxy scenarios only.
26-6527-106 Alc-Ipv6-
Secondary-Dns
The IPv6 address of the secondary DNSv6 server for this subscribers
connection and maps to DNS Recursive Name Server option 23' (RFC 3646) in
DHCPv6. This attribute is an alternative for [26-4874-48] ERX-Ipv6-
Secondary-Dns.
Applicable in proxy scenarios only.
26-6527-126 Alc-Subscriber-
QoS-Override
Used to override queue/policer parameters (CIR, PIR, CBS, MBS) and HQoS
parameters (aggregate rate, scheduler rate or root arbiter rate) configured at sla-
profile and sub-profile level. Enables per subscriber/host customization. Each
set of Alc-Subscriber-QoS-Override attributes in a RADIUS message replaces
the set of Alc-Subscriber-QoS-Override attributes from a previous message.
Hence the sla-profile and sub-profile QoS configuration is always used as the
base config. To undo a previously enabled RADIUS QoS-override and return to
the base config, send a CoA with at least one Alc-Subscriber-QoS-Override
attribute. The value part of each Alc-Subscriber-QoS-Override attribute must be
empty (For example, Alc-Subscriber-QoS-Override += i:q:2:). Wrong
formatted attributes or too many attributes (see limits) are treated as a setup
failure or result in a CoA NAK.
