Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.1(10) but
may also occur in other releases.
Workaround: There is no workaround.
• CSCea62753
Symptoms: Fragments produced on a Route Switch Processor (RSP) may be corrupted. The
fragments may have extra bytes of garbage that may cause the remote end to drop the packets since
the remote end cannot rebuild the packets.
Conditions: This symptom occurs on a Cisco 7500 router that is configured for Frame Relay
fragmentation 12 (FRF.12) on a Packet-over-SONET (POS) subinterface.
Workaround: There is no workaround.
• CSCec87736
Symptoms: TX Simple Network Management Protocol (SNMP) counters do not update on Fast
Ethernet subinterfaces for distributed Cisco Express Forwarding (dCEF) traffic.
Conditions: This symptom is observed on Cisco IOS Release 12.0(26)S and Release 12.3. The
hardware is DEC21140A, and the interface receiving the traffic is not located on the same Versatile
Interface Processor (VIP).
Workaround: There is no workaround.
• CSCed08399
Symptoms: A Cisco 7500 series may generate spurious memory accesses at a VIP.
Conditions: This symptom is observed when CRTP is enabled on the interfaces of the VIP.
Workaround: There is no workaround.
• CSCed29590
Symptoms: An interface on a Cisco 7500 series that is configured for distributed Multilink PPP
(dMLP) may stop transmitting data.
Conditions: This symptom is observed when the links in an MLP bundle flap. When the router
detects that the interface does not transmit data, the router automatically resets all Versatile Interface
Processors (VIPs) to restore proper functioning.
