Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: Occurs when MAC out-of-band synchronization is enabled in a distributed forwarding
system
Workaround: There is no workaround
CSCso57001
Symptoms: Router crashes when interfaces flap and the device is running the MetroE IPSLA
feature.
Conditions: When the device is set to automatically start jitter/ping probes and the interfaces flap,
it results in a crash when trying to re-create auto generated MetroE operations.
Workaround: There is no workaround.
CSCso57407
Symptoms: The standby Router resets and goes to RPR mode due to this config-sync issue. On Cisco
7600 platform upgrading an image from Cisco IOS Release 12.2(33)SRB to Cisco IOS Release
12.2(33)SRC may fail and the redundant routers will operate in RPR mode if the following
command is configured under an interface. interface TenGigabitEthernet2/0/0 l2protocol-tunnel
drop-threshold lldp 20.
The problem can be verified by executing the following show command.
show redundancy config-sync failures mcl Mismatched Command List
----------------------- interface TenGigabitEthernet2/0/0 ! "interface" -
l2protocol-tunnel drop-threshold lldp 20 ! "interface"
Conditions: The Cisco 7600 routers running Cisco IOS Release 12.2(33)SRB or Cisco IOS Release
12.2(33)SRC will observe the problem only if the configuration command l2protocol- tunnel
drop-threshold lldp 20 is configured under the interface.
Workaround: The problem can be worked around by entering no l2protocol-tunnel drop-threshold
lldp 20 under the interfaces.
CSCso57886
Symptoms: A Cisco IOS device may crash with a data bus error exception and stack trace PC =
0xA0000100
Conditions: Device is running normal production traffic. Presence of malformed punted RP packets
in this network caused the issue.
Workaround: There is no workaround.
CSCso59251
Symptoms: An interface on ESM20G goes down.
Conditions: Occurs when the interface has a 50 EVC on it. Seen on router using
rsp72043-adventerprisek9_wan_d/jointfilesconvert/422273/bg-mz.srb_throttle_033008 image.
Workaround: A shut/no shut will correct the symptom.
CSCso59390
Symptoms: After second switchover, a Cisco 7600 only forwards downstream traffic at 100 pps rate
to the ISG IP client.
Conditions: The 7600 router has the sip400 linecard on the access side and a WS-X6704-10GE card
on the core side. IP data traffic were sending bidirectionally at rate 500 pps with 128 bytes packet
size. After the first SSO, traffic were not impacted and both directions were able to forward at 500
pps, but after the second SSO downstream traffic rate dropped to 100 pps.
500 pps --------> sip400- 7613- 6704-------------> 500 pps 100 pps <-------- sip400- 7613-
6704-<------------ 500 pps
