Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: This problem has only been seen with Cisco IOS Release 12.2(33) SRB2. The exact
trigger is still unknown.
Recovery: To recover connectivity, there are two options. Option 1 is preferable since it causes less
traffic interruption. If Option 1 does not work, then Option 2 should be performed. 1. Attach to the
switch processor (remote login switch) and issue the command: test fpoe index 0 FFFF restore 2.
Reload the ingress SIP-400 linecard: hw-module module mod reset
Workaround: To prevent issue from occurring in 12.2(33)SRB2, diagnostics can be disabled on the
SIP-400 with the following command:
Router(config)#no diagnostic monitor module "slot#" test 1
• CSCsl50774
Symptoms: Linecard crashes repeatedly during boot after an unsuccessful FPD upgrade.
Conditions: Affects Cisco IOS Release 12.2SRB and will prevent the linecard from booting
Workaround: There is no workaround.
• CSCsl51380
Symptoms: Sup720 has periodic consistency checker for TCAM and SSRAM, from shadow to
hardware which write to hardware when an inconsistency is detected between shadow and actual
hardware. However, on a Sup720 and a Sup32 there is no verification to check whether the write was
successful, and no syslog or notification is given to notify persistent hardware entry failures.
Conditions: The symptoms are observed on a Sup720 and Sup32.
Workaround: There is no workaround.
• CSCsl51395
Symptoms: The device crashes when hw-module reset issued for the 6748 DFC card. Port Manager
Internal Software Error and tracebacks are also consistently seen with the line card when shut/no
shut or Hw-module reset was issued.
Conditions: Applies to Cisco IOS Release 12.2SX and related releases.
Workaround: There is no workaround.
• CSCsl51607
Symptoms: A router is not able to ping the second hop through the serial link that is configured with
multilink virtual-template and encap ppp, although it can ping the next hop. Packets directed to other
router through static route via virtual-access are getting dropped.
Conditions: This symptom is seen in the Cisco IOS Release 12.2SR images
c7200-ipbase-mz.autobahn76_111707 and c7200-ipbase-mz.122-32.8.99.SR.
Workaround: There is no workaround.
• CSCsl51765
Symptoms: The router crashes on entering the no t1 channel-group command.
Conditions: Occurs when the command is issued on a CT3 SPA on a SIP-400
Workaround: There is no workaround.
• CSCsl51848
Symptoms: Router crashes when a command is entered from the aux console to remove an interface.
Conditions: Occurs when a show command for that interface is presently paused at the "more"
prompt on the main console. The show commands are "show controllers serial" and "show interface
serial".
