Limitations and Restrictions
Support for RADIUS Attributes 52 and 53
The RADIUS Attributes 52 and 53 feature introduces support for Attribute 52 (Acct-Input-Gigawords)
and Attribute 53 (Acct-Output-Gigawords). Attribute 52 keeps track of the number of times the
Acct-Input-Octets counter has rolled over the 32-bit integer throughout the course of the provided
service; Attribute 53 keeps track of the number of times the Acct-Output-Octets counter has rolled over
the 32-bit integer throughout the delivery of service. Both attributes can be present only in
Accounting-Request records where the Acct-Status-Type is set to “Stop” or “Interim-Update.” These
attributes can be used to keep accurate track of bill for usage.

Support for RADIUS Attribute 77
The RADIUS Attribute 77 feature introduces support for Attribute 77 (Connect-Info) to carry the textual
name of the virtual circuit class associated with the given permanent virtual circuit (PVC). (Although
attribute 77 does not carry the unspecified bit rate (UBR), the UBR can be inferred from the class name
used if one UBR is set up on each class.) Attribute 77 is sent from the NAS to the RADIUS server in
Accounting-Request and Accounting-Response packets.

Limitations and Restrictions
•
The number of sessions and tunnels supported for the NRP-2 and NRP-2SV modules in Cisco IOS
Release 12.2(4)B3 changed to support of 6000 sessions per 2000 tunnels. See
Release 12.2(4)B3 changed to support of 6000 sessions per 2000 tunnels. See
and
for more information.
•
L2TP Multihop by remote tunnel hostname is not supported in Cisco IOS Release 12.2(4)B7. L2TP
Multihop by domain is supported in Cisco IOS Release 12.2(4)B7 by entering the lcp renegotiation
always command on the L2TP network server (LNS) vpdn-group.

When you flap an ATM subinterface that has traffic shaping enabled, the NRP-2SV SAR can fail. If
this occurs, all sessions will eventually timeout and disconnect. This issue can also occur when you
change vc-class parameters. If you use traffic shaping and you need to change configurations related
to virtual circuits with traffic shaping configured, you must shutdown the ATM main interface, make
your configurations changes, then bring up the ATM main interface.
