Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S4
Workaround: There is no workaround.
• CSCed82964
Symptoms: L2 loadbalancing might be affected on an egress link bundle.
Conditions: This symptom is observed a Cisco 12000 series when the ingress interface is a regular
Engine 2 interface and when the member interfaces in the bundle are toggled.
Workaround: Enter the config mode of the port channel and exit.
• CSCee16205
Symptoms: The committed information rate (CIR), normal burst, and maximum burst of the police
(percent) command in a policy map are set incorrectly.
Conditions: This symptom is observed when the policy map is attached to an MLP interface that is
configured for LFI and that is in the “DOWN” state.
Workaround: Attach the policy map when the MLP interface is in the “UP” state.
• CSCee16725
Symptoms: MPLS VPN VRF labels fail to be updated onto core-facing line cards such that the VPN
traffic entering the core-facing line cards is punted to the RP.
Conditions: This symptom is observed in a setup with two parallel paths between a PE router and a
CE router that run Cisco IOS Release 12.0 S. There are around 10,000 VRF routes advertised
through both the eBGP sessions that are established between the PE router and the CE router. When
the link flaps, the next hop of all the BGP routes changes to the next hop via the other link. When
this situation occurs, the core-facing line cards may miss the label forwarding entry for some of the
VPN prefixes.
Workaround: To recover from the problem after it has occurred, enter the clear cef linecard
command on the affected core-facing line card.
To avoid the problem from occurring, do not redistribute the PE-CE link subnet into BGP.
• CSCee19222
Symptoms: An MLP bundle configured between a Cisco 7500 series and any other router may not
be able to switch traffic when dCEF is enabled on the Cisco 7500 series.
Conditions: This symptom is observed when LFI is enabled with one member link in the MLP
bundle.
Workaround: Either remove dCEF or remove LFI. (A combination of CEF and MLP is not
supported.) Note that if there are two member links in the interleaving-enabled MLP bundle, the
problem does not occur.
• CSCee27276
Symptoms: A router shows a constant increase in the holding memory for the L2TP Daemon
process.
Conditions: This symptom is observed when invalid L2PTv3 control packets are sent from a peer
router. Invalid packets means packets without all the mandatory attribute value pairs.
Workaround: There is no workaround.
• CSCee31196
Symptoms: An LDP session over a tunnel interface may drop and not come back up.
Conditions: This symptom is observed on a Cisco router running Cisco IOS Release 12.0(27)S1
when auto-tunnel traffic engineering is configured and when RSVP label distribution is configured
in the MPLS core.
