Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S1
Irrespective of whether or not the mode of the controller of the PA-MC-8TE1 port adapter is set
to T1 or E1, you insert or remove a standby RSP via an OIR.
Workaround: Enter the card type {t1 | e1} slot [bay] command on the PA-MC-8TE1+ port adapter
and ensure that none of the controllers on this port adapter are shut down.
CSCin88718
Symptoms: All channels on a PA-MC-2T3+ port adaptor stop sending traffic although they continue
to receive packets. All interfaces will remain in up/down state.
Conditions: Once we send greater than linerate over the port adaptor, for a little while the PA locks
up and never returns to normal working state.
Workaround: Perform resurrect operation on the PA. Note: this will affect all interfaces on that PA.
CSCsa87986
Symptoms: A router may intermittently transmit corrupt PPP packets. When you enter the debug
ppp nego and debug ppp errors commands, it appears that “protocol reject” packets are received
from the remote end.
Conditions: This symptom is observed on a Cisco 7500 series that has only one OC3 POS port
adaptor per VIP and that is configured for PPP encapsulation.
Workaround: There is no workaround.
CSCsb04481
Symptoms: CEF may fail and the following error message is generated:
Interface Serial0/0:63 changed state to down
%CT3-3-LOVEFAIL: CT3-SW-PA-0/0: failed to send T3 line state change love
letter
%AMDP2_FE-5-LATECOLL: Ethernet0/0 transmit error
Conditions: This symptom is observed on a Cisco 7500 series that is configured with a channelized
T3 port adapter.
Workaround: There is no workaround.
IP Routing Protocols
CSCdz84521
Symptoms: Selective Packet Discard (SPD) with an IP precedence of 6 and 7 may not function
correctly. Packets may be treated as nonpriority packets. SPD is used when a queue is filling (for
example, because of a flap or change) and routing traffic must be guaranteed a high priority and not
dropped while the interface recovers. In this situation, routing traffic with an IP precedence of 6 and
7 is not given proper priority, and the recovery process may be delayed.
Conditions: This symptom is observed with incoming traffic on any interface of a Cisco 7200 series
and may be observed on other Cisco platforms as well.
Workaround: There is no workaround.
CSCec23167
Symptoms: During BGP scalability testing, error messages and tracebacks similar to the following
ones may be logged, indicating a difficulty with TCP and buffer usage:
%SYS-2-MALLOCFAIL: Memory allocation of 4692 bytes failed from 0x6076F714,
align
Pool: I/O Free: 11143248 Cause: Memory fragmentation
