Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S6
Conditions: This symptom has been observed in Cisco IOS Release 12.0(32)SY1 when using a
configuration with a large number of serial interfaces configured, including a 8xDS1 MFR bundle.
The MFR interface had a corresponding point-to-point subinterface with one DLCI defined. The
subinterface was pollable before removal and insertion of the card, but the ifIndex is missing
afterward.
Workaround: By reloading the router, or removing the subinterface and readding it, the ifIndex will
be recreated.
CSCsg32015
Symptoms: Port mode EoMPLS, after CE gigE interface is bounced, the PE Eng3 gigE interface
does not stay up and keep on flapping until you bounce the PE gigE interface as well. This problem
does not happen when VLAN is configured.
CSCsg36725
Symptoms: A memory leak and memory exhaustion may occur when QoS policies are updated on
40,000 sessions.
Conditions: This symptom is observed on a Cisco 10000 series but may also affect other platforms.
Workaround: There is no workaround.
CSCsg37485
Symptoms: After removing and re-applying a policy-map with hierarchical class-based policer on a
Vlan sub-interface on an Engine5/SIP-601 line card, all policer counters displayed in show
policy-map interface are zero despite traffic being sent through the interface, and the policer no
longer drops excess traffic when configured to do so.
This symptom could also affect other SIP-601 interfaces/SPAs and other ingress QoS
configurations.
Condition: This symptom has been observed under the following conditions:
1. There is a hierarchical shaper configured in the outbound direction on the main interface
(L3/nC/mD ISE QoS model).
2. Netflow is enabled on the main interface.
Workaround: There is no workaround other than avoiding the above conditions. A line card reload
temporarily fixes the problem, but once the configuration is toggled again, the symptom resurfaces.
CSCsg40032
Symptoms: Perform a line card reload on an Engine 0 CT3 or DS3 line card, upon recovery any
frame-relay sub-interfaces on those line cards which have rate-limit output configured will no longer
have this applied.
Conditions: This symptom has been observed when performing a line car d reload.
Workaround: Reload of the router or a reload of the ingress line card resolves the issue.
CSCsg40339
Symptoms: MPLS OAM pings and trace from tunnel head to tail fail.
Conditions: MPLS pings and traceroutes are sent from tunnel headend to tail. They were seen failing
at penultimate hop when the router had E4+ ingress line card and E5 egress line card. When E4+ is
used both as ingress and egress line card, issue is not seen.
Workaround: There is no workaround.
CSCsg42604
Symptoms: OC48 interface on 2xOC48 SPA starts flapping and does not recover.
