Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCso74922
Symptoms: Resilient Ethernet Protocol (REP) state flaps after line card reset
Conditions: Occurs on routers running Cisco IOS Release 12.2(33)SRD with SIP600 ports
configured as REP edge ports.
Workaround: There is no workaround.
• CSCso84567
Symptoms: Non-TCP traffic passing through the device is punted to the control plane policer. When
Control Plane Policing (CoPP) is configured, the bridge result is changing to policy route because
WCCP is being applied to all IP packets of a WCCP service.
Conditions: Both WCCP and CoPP must be enabled for this issue to occur.
Workaround: There is no workaround.
• CSCso88138
Symptoms: When there is a link flap or a reload, RSVP shows that the interface is down while
actually the interface is up. Because of this, the tunnel may take a backup path even when the
interface is up.
Conditions: Unknown at this time.
Workaround: Perform a shut/no shut on the interface.
• CSCso90058
Symptoms: MSFC crashes with Red Zone memory corruption.
Conditions: This problem is seen when processing an Auto-RP packet and NAT is enabled.
Workaround: There is no workaround.
• CSCso90970
Symptoms: The no ip proxy-arp command that is configured under ISG enabled interface is not
working.
Conditions: This symptom is observed on the ethernet interface, where an ip subscriber command
is configured. Same interface allows disabling IP Proxy ARP with the no ip proxy-arp command,
but the command is ignored.
Workaround: There is no workaround.
• CSCsq04355
Symptoms: Customer mistakenly modified the service module SPAN session which caused high
CPU on the switch. This caused the interface to flap, bringing down Hot Standby Routing Protocol
(HSRP), Open Shortest Path First (OSPF) and other protocols resulting in an outage.
Conditions: Occurs when manipulating the service module SPAN session
