• The time taken to match the packet is fixed, so that latency of the packets are smaller (significantly
in the case of large ACLs) and more importantly, consistent, allowing better network stability and
more accurate transit times.

Vendor-Proprietary RADIUS Attributes
Remote Authentication Dial-In User Service (RADIUS) attributes are used to define specific authentication,
authorization, and accounting elements in a user profile, which is stored on the RADIUS daemon. Cisco
supports a variety of vendor-proprietary RADIUS attributes. For additional information, refer to the appendix
“Radius Attributes” in the Cisco IOS Security Configuration Guide, Release 12.2 on Cisco.com:

SNMP Features and Enhancements
Multiple Cisco IOS releases that support the Cisco uBR7200 Series include enhanced Simple Network
Management Protocol (SNMP) features:
• Individual SNMP Trap Support, page 1-109
• LinkUp/Down Traps Support (RFC 2233), page 1-110
• SNMPv2C, page 1-110
• SNMPv3, page 1-111
• SNMP Cable Modem Remote Query, page 1-111
• SNMP Management Information Base (MIB) Enhancements, page 1-111
• SNMP MIBs Changes and Updates in Cisco IOS Release 12.3(9a)BC, page 1-117
• SNMP Warm Start Trap, page 1-119
Individual SNMP Trap Support
The Individual SNMP Trap Support feature adds the ability to enable or disable SNMP system
management notifications (traps) individually. SNMP traps that can be specified are “authentication”,
“linkup”, “linkdown”, and “coldstart.” This feature expands the functionality of the snmp-server enable
traps command.
Note When the snmp-server enable traps command is given without any options, it enables all traps, which
can generate a significant number of traps at key events, such as system power-up. If the SNMP queue
is not large enough to handle all of the traps, new traps will be dropped without notification until the
existing traps are sent and slots become available in the queue.
