RADIUS Attributes Reference

101 Error-Cause The Error-Cause Attribute provides more detail on the cause of the problem if
the NAS cannot honor Disconnect-Request or CoA-Request messages for some
reason. It may be included within Disconnect-ACK, Disconnect-NAK and
CoA-NAK messages. The Error-Causes are divided in 5 blocks. Range [400-
499] is used for fatal errors committed by the RADIUS server. Range [500-599]
is used for fatal errors occurring on a NAS or RADIUS proxy. Ranges [000-199
reserved], [300-399 reserved] and [200-299 used for successful completion in
disconnect-ack/coa-ack] are not implemented.
123 Delegated-IPv6-
Prefix
Attribute that carries the Prefix (ipv6-prefix/prefix-length) to be delegated via
DHCPv6 (IA-PD) for the LAN side of the user (IPoE, PPPoE). Maps to
DHCPv6 option IA-PD [25] sub-option IA-Prefix [26] Prefix. An exact
Delegated-prefix-Length [DPL] match with configure service <service-id>
subscriber-interface <ip-int-name> ipv6 delegated-prefix-length [48..64] is
required with the received attribute prefix-length unless a variable DPL is
configured (configure service <service-id> subscriber-interface <ip-int-
name> ipv6 delegated-prefix-length variable). In the latter case multiple hosts
for the same group-interface having different prefix-length [48..64] per host are
supported. Simultaneous returned attributes [123] Delegated-IPv6-Prefix and
[26-6527-131] Alc-Delegated-IPv6-Pool are handled as host setup failures.
Attribute is also used in CoA and Disconnect Message (part of the ESM or AA
user identification-key). Attribute is omitted in accounting via configure
subscriber-mgmt radius-accounting-policy <name> include-radius-
attribute no delegated-ipv6-prefix.
26-2352-1 Client-DNS-Pri The IPv4 address of the primary DNS server for this subscribers connection and
maps to PPPoE IPCP option 129 Primary DNS Server address or DHCPv4
option 6 Domain Server. Is an alternative for 26-4874-4 ERX-Primary-Dns or
26-6527-9 Alc-Primary-Dns.
26-2352-2 Client-DNS-Sec
A IPv4 address of the secondary DNS server for this subscribers connection and
maps to 'PPPoE IPCP option 131 Secondary DNS Server address or DHCPv4
option 6 Domain Server. Is an alternative for 26-4874-5 ERX-Secondary-Dns
or 26-6527-10 Alc-Secondary-Dns.
26-2352-36 Ip-Address-Pool-
Name
The name of an assigned address pool that should be used to assign an address
for the user and maps to dhcpv4 option[82] vendor-specific-option [9] sub-
option [13] dhcpPool if option is enabled on the node (configure service
<service-id> subscriber-interface <ip-int-name> group-interface <ip-int-
name> dhcp option vendor-specific-option pool-name). Alternative to [88]
Pool-Name and [26-4874-2] ERX-Address-Pool-Name. Framed-Pool names
longer than the allowed maximum are treated as host setup failures.
Simultaneous returned attributes Pool-Names [8] and Framed-IP-Address are
also handled as host setup failures.
