Release Notes for Catalyst 6000 Family Software Release 5.x 5
Features for Supervisor Engine Software Release 5.3
• On switches with a Policy Feature Card (PFC):
Note IPX VACLs, QoS ACLs, COPS-DS, and RSVP for Qualitative Service were introduced
in software release 5.3(1a)CSX but were not fully tested; you were instructed not to use them.
These features can be used in software releases 5.3(3)CSX or later as they have been fully
tested.
— VLAN access control lists (VACLs) using IP, IPX, and MAC ACLs.
VACL enhancements in software release 5.3(3)CSX are as follows:
A VACL redirect ACE allows a unicast flow to be specified.
— Common Open Policy Service (COPS) for Differentiated Services (DS) allows QoS to be
configured from a central policy decision point server.
— Resource reSerVation Protocol (RSVP) for Qualitative Service allows hosts to request QoS.
— Remote SPAN (RSPAN) supports source and destination SPAN ports on other compatible
switches.
— Quality of service (QoS) supports classification, marking, and policing using IP, IPX, and
MAC ACLs.
— Accelerated Server Load Balancing (ASLB) support enables Catalyst 6000 family switches
to cache Cisco LocalDirector load balancing flows, accelerating the performance of the
LocalDirector, which is a network appliance with a secure, real-time, embedded operating
system that intelligently load balances IP traffic across multiple servers (see the
Catalyst 6000 Family Accelerated Server Load Balancing Installation and Configuration
Note).
ASLB enhancements in software release 5.3(3)CSX are as follows:
A TCP port can be a wildcard (0).
Up to 1024 virtual-IP addresses and TCP port pairs are supported.
Note Accelerated Server Load Balancing was previously called LocalDirector Accelerator in
these release notes.
• On switches with a Multilayer Switch Feature Card (MSFC):
— IP Multilayer Switching (MLS) provides high-performance hardware-based Layer 3
switching of IP unicast traffic,offloading processor-intensive IP packetrouting from network
routers.
— IP Multicast Multilayer Switching (IP MMLS) provides high-performance hardware-based
Layer 3 switching of IP multicast traffic, offloading processor-intensive IP multicast packet
routing from network routers.
— IPX MLS provides high-performance hardware-based Layer 3 switching of IPX unicast
traffic, offloading processor-intensive IPX packet routing from network routers.
— Standard and extended IOS access control lists (ACLs) at wire rate.
— Netflow Data Export (NDE) allows a summary of intersubnet Layer 3 traffic statistics for all
expired flows to be periodically exported to a network management data collector.
