OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
Conditions: The symptom is observed on Cisco 12000 series Engine 3 channelized line cards
(OC-48 or 4XOC-12 channelized to DS-3) that functions in an 1+1 APS configuration. However the
symptom could occur on any channelized APS interface.
Workaround: Enter the shutdown command followed by the no shutdown command on the affected
interfaces.
• CSCin33783
Symptoms: Entering the shutdown interface configuration command followed by the no shutdown
interface configuration command on an Gigabit Ethernet interface may prevent customer
edge-to-customer edge (CE-to-CE) pings from going through.
Conditions: This symptom is observed when Ethernet over Multiprotocol Label Switching
(EoMPLS) is configured in VLAN mode on the Gigabit Ethernet interface of a Network Processing
Engine G1 (NPE-G1) on a Cisco 7200 series.
Workaround: Configure EoMPLS in VLAN mode on a port adapter such as a Gigabit Ethernet or
Fast Ethernet port adapter.
• CSCin41269
Symptoms: A controller of an 8-port multichannel T1/E1 PRI port adapter (PA-MC-8TE1+) may fail
to come up after the router has booted up.
Conditions: This symptom is observed on a Cisco router that is configured with a PA-MC-8TE1+.
The symptom is platform independent and port adapter dependent.
Workaround: Enter the shutdown controller configuration command followed the no shutdown
controller configuration command on the affected controller.
Alternate Workaround: Enter the clear counters user EXEC or privileged EXEC command on the
affected interface of the PA-MC-8TE1+.
• CSCin52138
Symptoms: When flaps occur on an Inverse Multiplexing over ATM (IMA) group interface on which
the Any Transport over MPLS (AToM): ATM Cell Relay over MPLS: VC Mode feature is
configured, input packets may be switched via Cisco Express Forwarding (CEF).
Conditions: This symptom is observed on a Cisco 7500 series that has an IMA group interface that
is configured on a Versatile Interface Processor (VIP).
Workaround: Perform an online insertion and removal (OIR) of the VIP.
• CSCin61140
Symptoms: A line card reloads continuously after an OIR.
Conditions: This symptom is observed when the line card has MFR and a service policy configured.
Workaround: Remove the service policy before performing an OIR.
• CSCin62978
Symptoms: A FlexWAN, enhanced FlexWAN, or Versatile Interface Processor that has a PA-MC-E3
or PA-MC-T3 installed may crash.
Conditions: This symptom is observed under rare conditions in a stress situation with dFLI and
dCRTP configured.
Workaround: There is no workaround.
