You may misunderstand the conditions under which the Node Up and Node Down
events are generated. You only get the Node Down event when the last
interface
goes down. And you get the Node Up event when all interface are up. So if
you have
a router with all interfaces up, Admin Down, or unmanaged (so node status
is Normal),
and one interface goes down and then up, the events you will see are
Interface Down, Node Marginal
then
Interface Up, Node Up.
On the other hand, if you have a server where one or more interfaces are
always down
(node status is marginal) and only one interface is normally up, and that
interface goes
down and then up, you will see
Interface Down, Node Down
followed by
Interface Up, Node Marginal.
This is why most people pay more attention to the Interface events than the
Node events.

Subject: [NV-L] rulsets and routers:-(
dear all,
i've got a problem with some reports about routers in my wan. i defined
rulsets to get all information about node up and down from all routers.
first i query smartset where all routers are standing, then trap settings
monitor 58916864 or 58916865 event. next, action executes script described
below :
echo "`date` Node " $NVATTR_2 "is " $1 >> /usr/OV/admin/log/$2/$NVATTR_2.
it requires variables depending on traps - DOWN or UP. the problem i've got
is that i receive most of the time sth like that in the reports:
Wed Apr 18 07:07:33 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Wed Apr 18 08:34:21 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Wed Apr 18 20:21:32 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Thu Apr 19 02:55:33 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Sat Apr 21 07:05:59 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Sun Apr 22 16:15:29 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Tue Apr 24 05:20:42 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Tue Apr 24 13:44:58 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
Wed Apr 25 00:20:38 DFT 2001 Node rou_101_1_eth0.isispl.natned.com.pl is
UP
so for me it doesn't make any sense cause there is no information about
DOWN
and i can't send this report to my manager. sometimes i receive opposite
entries without any information about UP:
Fri Apr 20 09:57:49 DFT 2001 Node rou_110_1_eth0.isispl.natned.com.pl is
DOWN
Wed Apr 25 01:55:08 DFT 2001 Node rou_110_1_eth0.isispl.natned.com.pl is
DOWN
Fri Apr 27 09:17:37 DFT 2001 Node rou_110_1_eth0.isispl.natned.com.pl is
DOWN
Mon Apr 30 12:58:15 DFT 2001 Node rou_110_1_eth0.isispl.natned.com.pl is
DOWN
i'm asking you what could be a reason and how to solve this problem? in
routers configuration i've got 'snmp-server host netvsrv public envmon
snmp'.
to recap i need to receive sth like that:
Mon Apr 16 18:31:26 DFT 2001 Node rou_130_1_eth0.isispl.natned.com.pl is
DOWN
Mon Apr 16 18:47:08 DFT 2001 Node rou_130_1_eth0.isispl.natned.com.pl is
UP
Tue Apr 17 14:12:01 DFT 2001 Node rou_130_1_eth0.isispl.natned.com.pl is
DOWN
Tue Apr 17 14:31:24 DFT 2001 Node rou_130_1_eth0.isispl.natned.com.pl is
UP
Wed Apr 25 01:39:34 DFT 2001 Node rou_130_1_eth0.isispl.natned.com.pl is
DOWN
Wed Apr 25 14:10:02 DFT 2001 Node rou_130_1_eth0.isispl.natned.com.pl is
UP.
i'm waiting for any solutions.
best regards
