Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.3.xSG
OL-26675-02
Limitations and Restrictions
– Attach the same monitor to multiple targets. CSCti43798
• ciscoFlashPartitionFileCount object returns an incorrect file count for bootflash:, usb0:, slot0:,
slaveslot0:, slavebootflash:, and slaveusb0:.
Workaround: Use the dir device command (for example, dir bootflash:) to obtain the correct file
count. CSCti74130
• If multicast is configured and you make changes to the configuration, Traceback and CPUHOG
messages are displayed if the following conditions exist:
– At least 10K groups and roughly 20K mroutes exist.
– IGMP joins with source traffic transit to all the multicast groups.
This is caused by the large number of updates generating SPI messages that must be processed by
the CPU to ensure that the platform is updated with the changes in all the entries.
Workaround: None. CSCti20312
• When attaching a existing policy-map (that is already applied to a control-port) to another
front-panel port, following message displays:
The policymap <policy-map name> is already attached to control-plane and cannot be
shared with other targets.
Workaround: Define a policy-map with a different name and then reattach. CSCti26172
• With traffic running, entering clear ip mroute * with larger number of mroutes and over 6 OIFs will
cause Malloc Fail messages to display.
You cannot clear a large number of mroutes at one time when traffic is still running.
Workaround: Do not clear all mroutes at once.
CSCtn06753
• 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.
• Energywise WOL is not “waking up” a PC in hibernate or standby mode.
Workaround: None. CSCtr51014
• The ROMMON version number column in the output of show module command is truncated.
Workaround: Use the show version command. CSCtr30294
• IP SLA session creation fails randomly for various 4-tuples.
Workaround: Select an alternate destination or source port. CSCty05405
