Release Notes for the Catalyst 4500 Series Switch, Cisco IOS Releases 15.2(2)Ex
Limitations and Restrictions
The XML output of show running-config command includes the following, which can then be 
parsed programmatically, as desired:
    
<mac><access-list><extended><ACLName>MACCOY</ACLName></extended></access-list></mac>
    <X-Interface> permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 
appletalk</X-Interface>
    <X-Interface> permit any host 65de.edfe.fefe xns-idp</X-Interface>
    <X-Interface> permit any any protocol-family rarp-non-ipv4</X-Interface>
    <X-Interface> deny   host 005e.1e5d.9f7d host 3399.e3e1.ff2c 
dec-spanning</X-Interface>
    <X-Interface> permit any any</X-Interface>
Although the Catalyst 4500 series switch still supports legacy 802.1X commands used in Cisco IOS 
Release 12.2(46)SG and earlier releases (that is, they are accepted on the CLI), they do not display 
in the CLI help menu.
Current IOS software cannot support filenames exceeding 64 characters. 
All software releases support a maximum of 32,768 IGMP snooping group entries.
Although you can configure subsecond PIM query intervals on Catalyst 4500 platforms, such an 
action represents a compromise between convergence (reaction time) and a number of other factors 
(number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route, 
etc.). You must account for those factors when configuring subsecond PIM timers. We recommend 
that you set the PIM query interval to a minimum of 2 seconds. By adjusting the available 
parameters, you can achieve flawless operation; that is, a top number of multicast routes per given 
convergence time on a specific setup.
With Cisco IOS Release XE 3.2.1SG, memory configuration is enabled:
Switch(config)# memory ?
  chunk    chunk related configuration
  free     free memory low water mark
  record   configure memory event/traceback recording options
  reserve  reserve memory
  sanity   Enable memory sanity
This configuration had been removed erroneously in a prior release.
The Catalyst 4510R switch does not support Supervisor Engines 6L-E. Installing an unsupported 
supervisor engine causes unpredictable hardware behavior that cannot be controlled by the software. 
Using an unsupported supervisor engine in a redundant slot might cause a supported supervisor 
engine in the other slot to malfunction.
The MAC address table is cleared while you switch between supervisor engines if either the 802.1s 
or 802.1w Spanning Tree Protocol is configured. To minimize address clearing and subsequent 
packet flooding, configure the edge ports as spanning-tree portfast and the link type as 
spanning-tree link-type point-to-point.
IP classful routing is not supported; do not use the no ip classless command; it will have no effect, 
because only classless routing is supported. The command ip classless is not supported because 
classless routing is enabled by default.
A Layer 2 LACP channel cannot be configured with the spanning tree PortFast feature.
Netbooting using a boot loader image is not supported.
When you deploy redundant supervisors in a Catalyst 4507R, for hardware that does not exist while 
the startup configuration file is being parsed, the configuration file for the hardware is not applied.
