Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: Race condition occurs while deleting Cisco Express Forwarding (CEF) entries from a
table.
Workaround: There is no workaround.
• CSCsr49316
Symptoms: A crash happens when the show ipv6 rpf x:x:x::x command is given.
Conditions: This symptom is observed only when there are more than 16 adjacencies for a single
static route. The crash happens when the show ipv6 rpf command is given for this particular static
route.
Workaround: There is no workaround. This problem occurs as long as there are more than 16
adjacencies for single static route even if some of them are not active.
• CSCsr50821
Symptoms: A router may crash when ARP hits through interrupt level.
Conditions: This symptom is observed when bridging is configured, but it may also be observed
when the ARP code hits by interrupt context, which is unpredictable.
Workaround: There is no workaround.
Further Problem Description: This defect was introduced via CSCsq05997. Cisco IOS Release 12.4
and 12.4T are not affected by this defect, but Cisco IOS Release 12.2S may be affected by this
defect.
• CSCsr55278
Symptoms: Fast switching of multicast packets may not occur on the interface of a PE router. All
multicast packets are forwarded in process switching.
Conditions: The symptom is observed after the interface is changed from a forwarding interface of
one VRF to another VRF.
Workaround: There is no workaround.
• CSCsr55865
Symptoms: Packet marking does not work in Cisco 7200, 7200p, and 7301 ipbase images.
Conditions: Applies to marking using "set" command. The "police" command works as expected.
Workaround: Use a different image.
• CSCsr55990
Symptoms: HSRP virtual MAC is dynamic instead of static on a Cisco 7600 after a reload.
Conditions: HSRP is configured under a routed vlan-based pseudowire:
interface Vlan X ip address 10.0.0.1 255.255.255.0 standby 1 ip 10.0.0.254 xconnect x.y.z.w
encapsulation mpls
Occurs when fast millisecond HSRP timers are used, and an HSRP interface delay is not configured.
Workaround: Perform a shut/no shut on the interface "vlan X". Or, as a preventive action, configure
standby delay minimum 60 on the interfaces. Testing has shown that after a reboot the entry is
installed correctly in the PFC/DFC.
• CSCsr56465
Symptoms: Line card MAC notification test fails when redundancy mode is changed from RPR to
SSO or SSO to RPR. SIP-400 Bus Connectivity Test failed when the following commands are
issued:
Conf t redundancy mode rpr
