Supported Juniper Networks VSAs
Table 40 on page 185 lists the Juniper Networks (Vendor ID 4874) VSAs supported
for Acct-Start, Acct-Stop, Interim-Acct, Acct-On, Acct-Off, Partition-Accounting-On,
and Partition-Accounting-Off messages.
The following notes are referred to in Table 40 on page 185:
1.
The attribute is not included in Acct-Stop messages that are sent when a user
session does not get established in one of the following situations.
■
The aaa accounting acct-stop on-access-deny command is enabled and
the authentication server sends an Access-Reject (deny) message.
■
The aaa accounting acct-stop on-aaa-failure command is enabled and the
authentication server issues an Access-Accept message (grant), but the AAA
configuration denies access for the user. The
aaa accounting acct-stop
on-aaa-failure is enabled by default.
■
The aaa accounting acct-stop on-aaa-failure command is enabled and the
user terminates before AAA receives the authentication response from the
authentication server.
2.
ERX routers send IPv6 accounting attributes in the Acct-Stop and Interim-Acct
messages (stop, interim) when they are configured to return these attributes and
when the subscriber is either an IPv6 subscriber or a combined IPv4/IPv6
subscriber in a dual stack. For an IPv4 subscriber, IPv6 accounting attributes are
not included in the accounting messages even if the IPv6 accounting is enabled.
In JUNOSe Release 10.1.x and lower-numbered releases, the combined accounting
statistics were retrieved at the layer 2. Therefore, error or discarded packets in
the layer 2 itself were excluded in these statistics. Because the layer 2 cannot
detect the error or discarded packets in the layer 3, the combined statistics also
include the error or discarded packets of the layer 3. In this release, with the
support for RADIUS VSAs for IPv6 accounting, the IPv6 statistics are retrieved
at the layer 3. To be consistent with the combined statistics, the error or discarded
packets of the layer 3 are also included in these IPv6 statistics.
3.
The ICR partition accounting messages comprise the following:
■
Partition-Accounting-On—Sent to the RADIUS server whenever an ICR
partition changes to the master state from the backup state. The
Partition-Accounting-On message has the same Acct-Status-Type attribute
