Caveats
Resolved FlexWAN Module Caveats in Release 12.1(22)E3
• 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(22)E3. (CSCin78325)
Resolved FlexWAN Module Caveats in Release 12.1(22)E2
• PA-A3-8T1IMA and PA-A3-8E1IMA port-adapter interfaces generate repeated “changed state to
up” messages without corresponding “changed state to down” messages. This problem is resolved
in Release 12.1(22)E2. (CSCin05262)
• EIGRP neighbors flap and output traffic is dropped when traffic on a PA-A3-8T1IMA or
PA-A3-8E1IMA port-adapter interface is 40 percent or more of the non-real time variable bit rate
(VBR-nrt) parameter. This problem is resolved in Release 12.1(22)E2. (CSCee50948)
Resolved FlexWAN Module Caveats in Release 12.1(22)E1
None.
Resolved FlexWAN Module Caveats in Release 12.1(22)E
• With a FlexWAN module, following a reload, you might see erroneous OIR-6-REMCARD messages
and the FlexWAN module might reset. This problem is resolved for Frame Relay interfaces in
Release 12.1(22)E. (CSCed53595)
• Operation, Administration, and Maintenance (OAM) permanent virtual circuits (PVCs) on
PA-A3-8T1IMA or PA-A3-8E1IMA interfaces are not active after an OIR. This problem is resolved
in Release 12.1(22)E. (CSCin65182)
• An administratively shut-down subinterface that is configured for Frame-Relay encapsulation might
forward packets. This problem is resolved in Release 12.1(22)E. (CSCed78803)
• Following OIR of a PA-MC-8TE1+ port adapter, the output queue might be stuck. This problem is
resolved in Release 12.1(22)E. (CSCec70301, CSCec70296)
• A service policy configured to allocate bandwidth to routing protocol control traffic on a fully
utilized PA-MC-8TE1+ port adapter E1 link does not prevent the traffic from being dropped. This
problem is resolved in Release 12.1(22)E. (CSCed36110)
• A 1-port E3 serial port adapter (PA-E3) might fail to recover to the “up/up” state even when the
original cause of the failure is corrected. This problem is resolved in Release 12.1(22)E.
(CSCec33028)
• The FlexWAN module may reload when it is booting up. This problem is resolved in
Release 12.1(22)E. (CSCec55445)
• 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(22)E. (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(22)E. (CSCin49458)
• The FlexWAN module might corrupt very small Frame Relay packets (for example, 2-byte X.25
SABM packets). This problem is resolved in Release 12.1(22)E. (CSCec59440)
