Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsm96785
Symptoms: You may observe a problem which the OSPF neighbor is down after switch-over in spite
of using OSPF Non-Stop Forwarding (NSF).
Conditions: This occurs with the following conditions: - "nsf cisco" is only affected. If "nsf ietf",
this problem does not occur. - You may observe this problem if the OSPF interface is
"point-to-multipoint non-broadcast" or "point-to-multipoint". If the interface is "broadcast", this
problem does not occur. - When this problem occurs after switch-over, DBD packet may not be
exchanged between two neighbors. And the neighbor is down in spite of NSF.
Workaround: Change the OSPF config to "nsf ietf" and change the OSPF interface to "broadcast".

Symptoms: The command hold-queue length in cannot be configured for port-channel interface.
Conditions: The symptom is observed with a Cisco 7600 series router after upgrading to Cisco IOS
Release 12.2(33)SRC.
Workaround: There is no workaround.
Further Problem Description: Queueing is not supported for port-channel with a Cisco 7600 series
router. The hold-queue is a legacy queueing command and is not supported.
CSCsm97297
Symptoms: Output direction ACL does not work.
Conditions: Occurs when ip cef accounting is enabled on a MPLS enabled router doing tag
disposition. If packets coming in are tagged, and they are going out of the router as untagged, the
output IP ACL may not work.
Workaround: Reconfigure the static route or clear the route.
CSCsm97560
Symptoms: MCL check failure is seen with upgrade fpd auto command.
Conditions: The problem is seen when performing ISSU downgrade from an IOS release supporting
the FPD feature to the one that does not support the FPD feature.

12.2(33.0.6)SRC ENGINEERING WEEKLY BUILD (c7200p-
advipservicesk9_li-mz.122-33.0.6.SRC). ARP keepalive is not found to be supported.

Conditions: Occurs when trying to use ISSU to upgrade a Cisco 7609 from Cisco IOS Release
12.2(33)SRB2 to Cisco IOS Release 12.2(33)SRC on Sup720 configured for SSO. After executing
the "issu runversion 6" which will reload the active, the switch goes into RPR redundancy with
currently active one having the new image SRC and the other one with the old SRB2 as the standby.
