Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(29)S
Conditions: This symptom is observed during AToM HDLC/PPP regression tests.
Workaround: There is no workaround.
• CSCee31618
Symptoms: Buffer leakage could occur when a high load of traffic is sent to an interface that has a
service policy enabled. This could result in ping failures or very long packet delay.
Conditions: The problem is observed with an MC-T3+ interface that is configured in unchannelized
mode, and the traffic consists only of small packets such a 64-byte packets.
Workaround: Manually configure the tx-ring-limit command to lower the number of packets that
can be placed on the transmission ring.
• CSCee34076
Symptoms: Routes that are removed soon after an SSO switchover occurs may remain in the CEF
table.
Conditions: This symptom is observed when VRFs are configured.
Workaround: There is no workaround.
• CSCee34094
Symptoms: A standby RP keeps crashing.
Conditions: This symptom is observed when both the snmp-server community string rw command
and the snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
command are configured.
Workaround: Remove the snmp-server community string rw command from the startup
configuration before rebooting the router. When the router has booted, reenter the snmp-server
community string rw command.
• CSCee35185
Symptoms: After reloading a Cisco platform, one of the RPs may reload, or the following error
message may be displayed:
%PARSER-4-BADCFG: Unexpected end of configuration file.
Conditions: This symptom may be observed on any Cisco platform that is configured with dual RPs
and that supports RPR+.
Workaround: There is no workaround.
• CSCee35331
Symptoms: A router may reload if removing the L2TP class is followed by removing the pseudowire
class.
Conditions: This symptom is observed on a router that runs Cisco IOS Release 12.0(28)S when both
removals are done in a very short time via an auto test script and when the L2TP sessions are already
established. This is a timing related issue.
Workaround: Wait at least 1 second before you remove the pseudowire class.
• CSCee35349
Symptoms: When you set up an L2TPv3 tunnel configured in the PW class, a ping cannot go through
from CE router 1 to CE router 2 until the ping is initiated by CE router 2.
Conditions: This failure occurs in Cisco IOS Release 12.0(28)S with a Fast Ethernet interface (not
with a serial or POS interface).
