APAR Error Description / Circumvention

-----------------------------------------------
When a snmpwalk is attempted using SNMPv1 or SNMPv3 on a system
with multiple TCP/IP interfaces to which the *DFTROUTE can be
bound, and the route isn't bound to the first interface in the
list, the index information isn't being passed back to the SNMP
manager correctly causing the snmpwalk to fail with a message
like:
Error: OID not increasing:
IP-MIB::ipDefaultRouterLifetime.ipv4."x.x.x.x".n
>= IP-MIB::ipDefaultRouterLifetime.ipv4."x.x.x.x".n

where x.x.x.x represents an IP address and n is the index number

CORRECTION FOR APAR MA44393 :
-----------------------------
SNMP getnext built the instance ID of the ipDefaultRouter OIDs
incorrectly if an IPv4 default route had been rebound to a
different line from what it was bound when TCP/IP was started. A
subsequent getnext from that OID may then return the same route.


The interface ID is now built correctly.

CIRCUMVENTION FOR APAR MA44393 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
