Yes, please report your problem to Support!!  We are trying to get NetView
6.0.1 working, and have lots of problems with HSRP interfaces.  We had a PMR
open for several weeks before we finally got Support to acknowledge that
there even was a problem.  In a conference call with Support, we found out
that network discovery of HSRP was redesigned in version 6, and I guess no
one had discovered the bugs until now.  Now the primary "trigger" for
identifying an HSRP interface is the MAC address from the ARP table; all
HSRP interfaces have the same prefix (00000C, or something like that).  The
sysName MIB object is not polled at discovery time, but is polled later
during the "HSRP poll", which is every 5 minutes as Leslie stated.  So, if
NetView discovers an HSRP interface, and adds it to the "wrong" device, it
will be deleted 5 minutes later when the HSRP poll occurs, and so on, and so
on . . . .

Chance, you might want to call Support and have them look at your
logs. FYI, Netview does re-check all HSRP interfaces every 5 minutes
to verify that they still go to the same system, and if not, it moves them.
It checks by looking at the router sysName reached by that address.
So you might start by checking to see that the sysNames are configured
on those devices and that they are unique.

Cordially,

Subject:  [NV-L] HSRP Interface messages



     I am receiving messages related to HSRP interfaces in Netview.

     Here is some background:

        Router A has 7 interfaces for which it is configured for HSRP. On
     interfaces 1,2,3 it has a priority of 200 and 4,5,6,7 a priority of
     100

        Router B is the peer router. It also has 7 interfaces. Interfaces
     4,5,6,7 are have priority of 200 and on 1,2,3 priority of 100.

     Router A is the active router for interfaces 1,2,3 and Router B is the
     active router for interfaces 4,5,6,7.

     The messages I am receiving start with an Interface down, then HSRP
     interface deleted, then interface deleted, then interface added, then
     HSRP interface added. They are in that order for interfaces 4,5,6,7 on
     router A.

     These messages are logged every 2 to 3 minutes.

     I am running Netview 6.01 on AIX 4.3.3. If this is not clear I will
     can send copies of my logs and what not.

     Thanks for your help!
