OL-2310-11
Caveats
Resolved FlexWAN Caveats in Release 12.1(20)E6
• Serial interfaces on a PA-MC-8TE1+ port adapter that are configured as part of a channel group
continue to process packets when the interface is in the “admindown” state. The counters in the
output of the show interfaces serial command might increment when the serial interface is shut
down. This problem is resolved in Release 12.1(20)E6. (CSCin78325)
Resolved FlexWAN Caveats in Release 12.1(20)E3
• Operation, Administration, and Maintenance (OAM) permanent virtual circuits (PVC) on
PA-A3-8T1IMA or PA-A3-8E1IMA interfaces are not active after an OIR. This problem is resolved
in Release 12.1(20)E3. (CSCin65182)
• An administratively shut-down subinterface that is configured for Frame-Relay encapsulation might
forward packets. This problem is resolved in Release 12.1(20)E3. (CSCed78803)
• With heavy traffic through a PA-MC-T3 or PA-MC-E3 port adapter, a FlexWAN module might
reload. This problem is resolved in Release 12.1(20)E3. (CSCin62978)
• With a high traffic load, PA-A3-OC3, PA-A3-T3, and PA-A3-E3 port adapters might display an
increasing “rx_no_buffer” counter in the output of the show controllers atm privileged EXEC
command and some PVCs configured on the PA-A3 port adapter might stop receiving traffic. This
problem is resolved in Release 12.1(20)E3. (CSCin49458)
Resolved FlexWAN Caveats in Release 12.1(20)E2
• When EoMPLS virtual circuits (VCs) are loadbalanced across an OSM-2+4GE-WAN+ physical
interface and a subinterface, the OSM reloads if you remove a service policy from the physical
interface. This problem is resolved in Release 12.1(20)E2. (CSCec65147)
• Illegal memory accesses when a dGRE test is configured on HSSI Frame Relay encapsulation for a
FlexWAN module might cause a reload. This problem is resolved in Release 12.1(20)E2.
(CSCin29514)
• A FlexWAN module is not detected during the boot process causing it to be ignored during the
startup configuration process. This problem is resolved in Release 12.1(20)E2. (CSCed00781)
• The FlexWAN module may reload when it is booting up. This problem is resolved in
Release 12.1(20)E2. (CSCec55445)
Resolved FlexWAN Caveats in Release 12.1(20)E
• Ignore messages from a 1-port multichannel STM-1 port adapter (PA-MC-STM-1) that reports a
large number of degraded minutes on an E1 controller. For example, after 15 minutes of operation
since startup, 35,000,000 degraded minutes might be reported and these values might increase every
second. Code violations might also be reported. This problem is resolved in Release 12.1(20)E.
(CSCec08973)
• When a Tributary Unit Alarm Indication Signal (TU-AIS) is inserted for an E1 tributary on a
PA-MC-STM-1 port adapter in a Synchronous Payload Envelope (SPE), packet corruption might
occur on the adjacent E1. This problem is resolved in Release 12.1(20)E. (CSCea66218)
• You can attach a service policy that contains invalid configuration to an interface. If you apply a
Frame Relay map-class with both input policing and output queuing to a DLCI twice, the FlexWAN
module might reload. This problem is resolved in Release 12.1(20)E. (CSCin52060)
