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, or 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-
S e c o n d a ry - D n s
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
(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.
