Resolved Caveats—Cisco IOS Release 12.0(32)S
tag2ip, with ip->tl < 20
tag2ip, with ip options packets
tag2ip, with ip options packets with bad ip hdr cksum
tag2ip, with ip options packets with ip->tl > L2
tag2ip, with ip options packets with ip->tl < 20
These bad packets cause packet corruption and a “TX192-3-PAM_PIM” error message on the E4+
line card and may even cause the E4+ line card to reset.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: There is no workaround.
Further Problem Description: The fix for this caveat enables the ISE line card to drop the
above-mentioned bad packets.

Symptoms: When an attachment circuit is configured for AToM pseudowire redundancy, an MPLS
core network failure on the primary pseudowire may not cause a switchover to the redundant (or
backup) pseudowire.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS
Release 12.2(27)SBA and on a Cisco 12000 series that runs a Cisco IOS interim release for
Release 12.0(31)S.
Workaround: There is no workaround.

Conditions: This symptom is observed on a Cisco 12000 series that is configured for Multicast VPN.

Symptoms: Links flap on a 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card after an RP
switchover has occurred.

Symptoms: On a Cisco 12000 series router with a 1xChOC12/DS1 ISE line card configured with
multilink MFR protocol and a MQC policy, after a reload the QoS does not get applied to the bundle.
The QoS goes to the suspend mode.
Conditions: The bundle loses its QoS policy when the router is reloaded. This problem is observed
when running Cisco IOS Releases 12.0(28)S1, 12.0(30)S, or an interim release for
Release 12.0(31)S.
Workaround: Remove the service-policy from the bundle and re-apply it.

Symptoms: After you perform an OIR of a PA-SRP-OC12 port adapter on a Cisco 7200 series, the
router may not show any nodes in the SRP ring and may stop forwarding traffic.
