Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S3
Note, however, that the implementations of Cisco LSP ping draft version 3 do not reply with
multipath lengths that can cause this crash.
• CSCuk50159
Symptoms: If CEF is disabled before a switchover is performed, configuring DCEF after the
switchover will not enable DCEF on the VIPs.
Conditions: This symptom is observed on a Cisco 7500 series that is running Cisco IOS
Release 12.0S and that is configured for High Availability.
Workaround: Make sure that DCEF is running before the switchover.
TCP/IP Host-Mode Services
• CSCeg20351
Symptoms: An RR is unable to negotiate the optimal MSS with their MP-BGP neighbors.
Conditions: This symptom is observed on a Cisco platform that runs Cisco IOS Release 12.0(28)S1,
that functions as an RR, and that has Path MTU Discovery (PMTUD) enabled. The symptom may
also occur in other releases.
Workaround: There is no workaround.
Wide-Area Networking
• CSCef68547
Symptoms: FR links on 6-port channelized T3 and 2-port OC-3-channelized-to-DS1/E1 line cards
may not recover when all of the links are removed and reconfigured for an MFR bundle. The same
symptom may occur on serial interfaces.
Conditions: This symptom is observed when all links are removed from and re-added to the bundle
while the bundle is briefly in a shut down state.
Workaround: To re-establish the bundles, enter the hw-module slot shelf-id/slot-number reload
command. You can also delete and reconfigure the MFR interface or the serial interfaces. To prevent
the symptom from occurring, wait a couple of seconds between entering the shutdown command
and the no shutdown command when you remove and reconfigure the MFR bundle or serial
interfaces.
• CSCeh33185
Symptoms: On a POS interface on a VIP4-80 that is running PPP, the interface goes down and
remains down. A manual shut and no shut of the interface is required to bring it up.
Conditions: This symptom is observed on a Cisco 7513 RSP that is running Cisco IOS
Release 12.0S.
Workaround: Enter the shut command and followed by the no shut command on the interface.
• CSCsa49019
