Hi All,
          I added a cisco 6506 with a SUP 720 to the seed file for snmp
polling only. It discoved the device and all interfaces and all are in a
green status for approximately 10 minutes. The devices will go into alarm
and I run a ping test which brings up the management interface (vlan99) and
then a demand poll. The demand poll runs for 10 + minutes.  If I delete all
interfaces (except vlan99) and demand poll the devices again, I get results
within seconds. Netview re-discovers all interfaces and all are green.   I
run a netmon trace and receive -

14:04:38 : .//nl_snmper.c[924] : timeout_snmps: op = 15 req = 7 reqid =
2096312 on E-S-WEB-ART01-ENT
14:04:38 : .//nl_snmper.c[695] : expired snmp E-S-WEB-ART01-ENT
(10.220.0.1) op = STATUS req = IFnumber reqid = 2096312
14:04:39 : .//nl_snmper.c[1195] : recv_snmp: from E-S-WEB-ART01-ENT
(10.193.253.51) op = HSRP req = SysName reqid = 2143107
14:04:39 : .//nl_snmper.c[619] : No Up interface for snmp poll, backing off
operation 2 for node E-S-WEB-ART01-ENT (10.220.0.1).
14:06:45 : .//nl_snmper.c[924] : timeout_snmps: op = 15 req = 7 reqid =
2143944 on E-S-WEB-ART01-ENT
14:08:24 : .//nl_snmper.c[924] : timeout_snmps: op = 15 req = 7 reqid =
2143944 on E-S-WEB-ART01-ENT
14:08:24 : .//nl_snmper.c[1195] : recv_snmp: from E-S-WEB-ART01-ENT
(10.193.253.51) op = STATUS req = IFnumber reqid = 2143944
14:08:24 : .//nl_snmper.c[1195] : recv_snmp: from E-S-WEB-ART01-ENT
(10.193.253.51) op = STATUS req = SNMPStatus reqid = 2152312

I also submitted the following - tcpdump -v host  IP address      and
receive the following results when device goes into alarm

Any suggestions would be appreciated..   Is there any other tcpdump
parameters I should use?

Thank, Dave
