RE: [nv-l] False alarm

[Oliver Bruchhaeuser <oliver.bruchhaeuser@de.ibm.com>]

if the interface is really up (can be
pinged) but is reported down per SNMP
this is either a bug in the routers
snmp agent or a config problem on the router.
Talk to your network guys.
This is not a NetView problem.

Oliver,
 
I ran the snmpwalk for the
ifIndex and the integer returned was (4). Then I ran the snmpwalk for the
status of the interface (4) and shows down. What do I do next?
 
Regards,
Ioannis

Ioannis,

first get the ifIndex of the IP Address in question from the ipAddrTable:
snmpwalk <router> ip.ipAddrTable.ipAddrEntry.ipAdEntIfIndex
Then look for the ifOperStatus for the concerning ifIndex:
snmpwalk <router> interfaces.ifTable.ifEntry.ifOperStatus

I assume it's down (config problem?) or the ifIndex is missing completely
(Firmware bug).

Don and Blane, 
  
Yes, the SNMP status polling is used. What resources should I look for?
The lines (interfaces) are Frame Relay to the branch (ATM in the backbone).

Are you using SNMP status polling for these routers ?
I have seen this when resources are low on the NetView server, which may
cause SNMP status polling to time out.

Hello list, 
  
I am facing the following problem: We have about 200 branches (ARN Nortel
routers) and for some branches about 10, the routers are shown as yellow.
When I check the interfaces I see that the WAN interface is red. When I
test the interface (ping) the interface responds and becomes green. After
some seconds it goes back to read state. Any ideas why this is happening
will be greatly appreciated.
  
Netview 7.1.1 
AIX 4.3 
ARN Nortel Routers 
  
Best regards,
