Caveats
Wide-Area Networking
• CSCds30986
Both 2x32-bit and 64-bit counters are incorrect when using Packet-over-SONET with Frame Relay
encapsulation on subinterfaces. There is no workaround.
Resolved Caveats—Cisco IOS Release 12.0(13)S
All the caveats listed in this section are resolved in Cisco IOS Release 12.0(13)S. This section describes
only severity 1 and 2 caveats.
Basic System Services
• CSCdm56157
A Cisco Route Switch Processor (RSP) might periodically display the following traceback:
IPC-5-INVALID: Sequence Structure port index=0x0 appears on the console.
When you enable the debug ipc errors EXEC command, the RSP might display the following
traceback:
IPC: SEQ_ERR ACK ... source seat 0x1000000 port 0x0
If you enter the show ipc stat command, the RSP produces “messages dropped on input” and “no
local port” errors.
This situation might occur when distributed Cisco Express Forwarding (dCEF) is enabled on line
cards. There is no workaround.
• CSCdr54711
On a Cisco router that is running Cisco IOS Release 12.0(10)S, aggregate NetFlow might report the
-cef layer ifIndex related to the physical interface instead of reporting the actual physical interface
ifIndex. There is no workaround.
• CSCdr71374
When output access control lists (ACLs) are configured on a Cisco 12000 series Gigabit Switch
Router (GSR) with Performance-48 or 3-Port Gigabit Ethernet line cards, packets that have a tag
imposed on them by these cards may be transmitted with the incorrect tag Time to Live (TTL).
There is no workaround.
• CSCdr77460
When an online insertion and removal (OIR) is performed, the IF-MIB ifTable, ifStackTable, and
ifNumber retains the old entries even though the associated interface layers have been removed.
There is no workaround.
• CSCdr90474
On a Cisco router that is running Cisco IOS Release 12.0(11.6)S, 64-bit Simple Network
Management Protocol (SNMP) counters might count backwards for in/out octets on idle Ethernet
interfaces. There is no workaround.
• CSCdr93938
The ifHCInOctets counter might report incorrect values during reloads for a Packet-over-SONET
(POS) interface on a Cisco 12000 series Gigabit Switch Router (GSR). There is no workaround.
