Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S4
• CSCsb54190
Symptoms: When you shut down an SRP interface on which the egress L2 priority is set to high by
entering the no shutdown interface configuration command, the PXF engine of a downstream router
may crash.
Conditions: This symptom is observed on a Cisco 10720.
Workaround: Do not enter the no shutdown interface configuration command. Rather, force a ring
wrap by entering the srp ips forced-switch command.
• CSCsb59294
Symptoms: The output is stuck on a Cisco 7200 series.
Conditions: This symptom is observed when a service policy attached to a T1 or E1 ingress interface
on one of the following port adapters:
–
PA- MC-2T1
–
PA-MC-2E1/120
–
PA- MC-4T1
–
PA- MC-8T1
–
PA-MC-8E1/120
–
PA-MC-8TE1+
Workaround: Remove the service policy from the egress interface.
• CSCsb62041
Symptoms: A newly created channelized interface may show packet and byte counts before any
traffic passes through the interface.
Conditions: This symptom is observed on a Cisco 12000 series. When a channelized interface is
deleted, the interface index is released. This interface index may be re-allocated when a new
channelized interface is created. The counters that are associated with the index need to be cleared
when an interface is deleted so that they are properly initialized if the index is subsequently
re-allocated to a new interface.
Workaround: There is no workaround. Although you can clear the interface counters via the CLI,
doing so does not prevent the symptom from occurring because but there is an internal counter that
is used in the Tx byte and packet counts and that may cause errors in the calculations.
• CSCsb75433
Symptoms: Distributed Multilink PPP (dMLP) packets are not switched via dCEF.
Conditions: This symptom is observed on a Cisco router that is configured with multilink bundles.
Workaround: There is no workaround.
• CSCsb93720
Symptoms: Using “no <any config CLI>” command may not get synchronized to standby RP. After
switchover, the interface shows configuration still enabled.
Conditions: This symptom is observed on a Cisco 12000 series router that is running the
c12kprp-p-mz/gsr-p-mz image of Cisco IOS Releases 12.0(30)S and 12.0(31)S.
Workaround: Reconfigure “no <any config CLI>” command after switchover.
