Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S1
• CSCeg25493
Symptoms: Several VIPs may crash at about the same time because of a bus error.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS
Release 12.0(26)S4 and that is configured with an RSP4 when the VIPs are configured for QoS but
have insufficient memory.
Workaround: Increase the amount of memory on the VIPs.
• CSCeg28402
Symptoms: Spurious memory accesses may occur on a Cisco 7500 series and may cause high CPU
usage on the RSP.
Conditions: This symptom is observed on a Cisco 7500 series that is configured for distributed
Multilink PPP (dMLP) and that functions in an MPLS network.
Note that packet switching for MPLS packets over MLP bundles is not supported at the RSP level
in Cisco IOS Release 12.0S.
Workaround: There is no workaround.
Further Problem Description: The fix for this caveat causes packets that are sent to the RSP for
switching to be dropped. Distributed forwarded packets are forwarded correctly.
• CSCeg29995
Symptoms: A router crashes when you create an IPv6 static neighbor entry that replaces an
incomplete ND cache entry and when you enter the shutdown interface configuration command
followed by the no shutdown interface configuration command multiple times on the interface that
connect to the neighbor.
Conditions: This symptom is observed when the following events occur:
1) The router receives and attempts to forward packets to a non-responding IPv6 neighbor, causing
the router’s ND cache entry for the IPv6 neighbor to be in the incomplete (INCMPL) state.
2) You create a static neighbor entry by entering the ipv6 neighbor command for the same
(non-responding) neighbor.
3) You enter the shutdown interface configuration command followed by the no shutdown interface
configuration command multiple times on the interface on which the static neighbor entry is defined,
or the interface is shut down and the static neighbor is deleted.
Workaround: Ensure that the IPv6 static neighbor is manually created before the processing of
traffic causes an incomplete ND cache entry to be created for the same neighbor.
• CSCeg30179
Symptoms: Removing a policy that has shape and bandwidth in the same class (in that same order)
may cause a router to crash.
Conditions: This symptom is observed when the router functions under a traffic load.
Workaround: There is no workaround.
• CSCeg31912
Symptoms: Ingress policing and bandwidth percent per-class do not function and limit traffic at the
configured bandwidth for MLFR links. The output of the show policy-map interface command
shows the configured bandwidth which differs from the actual bandwidth.
Conditions: This symptom is observed on a Cisco 7500 series after the router is reloaded.
Workaround: Remove the service policy and re-apply it to interface to enable correct calculation of
the interface bandwidth.
