Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsg39754
Symptoms: When DHCP snooping is configured on a VLAN, the redirect access list programmed
in TCAM permits a wide range of UDP ports from bootps/bootpc to 65xxx.
Conditions: UDP traffic to these destination ports (0x143, 0x243, 0xFF43) is being redirected to
Route Processor (RP). If “ip dhcp snooping limit” is not configured, then RP CPU goes to 100%.
Workaround: There is no workaround.
CSCsh48947
Symptoms: Some of the 48 power over Ethernet ports of a line card cannot be configured as “power
inline static” with the maximum power capacity, 15.4 watts, that a port can support.
Conditions: The number of supported ports depends on the power rating of the voice daughter board.
One or more ports may not operate at maximum capacity.
Workaround: There is no workaround.
CSCsi88974
Symptoms: While configuring a mediation device (MD), if the MediationSrcInterface is set to
loopback interface, traffic will cause MALLOC failures.
Conditions: Problem is seen when traffic rate is equal to or greater than 8000 packets per second.
Workaround: Do not use loopback0 as MD source interface.
CSCsj34557
Symptoms: Router displays following error message and reloads:

%Software-forced reload
Conditions: Occurred on a Cisco 7200 running the c7200-ik9s-mz.124-7a.bin image.
Workaround: There is no workaround.
CSCsj78403
Symptoms: A router may crash when the clear ip /jointfilesconvert/422273/bgp command is entered.
Conditions: Occurs on devices running BGP and configured as a route reflector client with
conditional route injection configured.
Workaround: Unconfigure conditional route injection.
CSCsk04318
Symptoms: Under the BGP router configuration mode, removing an address-family configuration
and then immediately reapplying the same configuration may cause the standby RP of a dual-RP
router to reload unexpectedly. Typically, the following configuration sync error will be reported:
Config Sync: Line-by-Line sync verifying failure on command: address-family ipv4 vrf NAME due
to parser return error
