We have a Catalyst 2950-48 with software C2950-I6Q4L2-M), Version 12.1(22)EA4, RELEASE SOFTWARE (fc1). And evetually we are having showed at HP Openview (Unix) the above message:


"Duplicate ifAlias value configured on different ifindexes - ignoring ifAlias on the following ifIndexes: 23 45 46 47 48"


And when this message is showed the switch appears as unavailable for around 10 to 20 seconds and then returns to normal state. Looking at switch there is no log at same time or close to it and as far as I tested it doesn't loose communication.

So, does anybody has faced this kind of problem already?

Tks,

Alex

It sounds like the ifAlias is the same for many of your interfaces. You should be able to do an snmpset on the ifAlias for ifIndex 23,45,46,47,48 and change the name .

You could also make some change in HPOV:


For Unix or Solaris

vi $OV_LRF/netmon.lrf and add the following:

-k useifAlias=false

Netmon.lrf should look like this:

netmon:netmon:

OVs_YES_START:ovtopmd,pmd,ovwdb:-P -k segRedux=true -k

useifAlias=false:OVs_WELL_BEHAVED:15:PAUSE

ovstop netmon

ovaddobj $OV_LRF/netmon.lrf

ovstart netmon


For NT/2000

cd C:\Openview\LRF

notepad netmon.lrf and add the following: -k useifAlias=false

Netmon.lrf should look like this:

netmon:netmon:

OVs_YES_START:ovtopmd,pmd,ovwdb:-P -k segRedux=true -k

useifAlias=false:OVs_WELL_BEHAVED:15:PAUSE

ovstop netmon

ovaddobj C:\Openview\lrf\netmon.lrf

ovstart netmon
