how to configure snmp trap to send only when linkup linkdown.
i don't want other alarm. only for linkup and linkdown.
the switch will only send traps for linkUp and linkDown?

I would try to define snmpview with corresponding OIDs only. Then you can use this view for notification. When you configure access rights you define readview, writeview and notifyview. I believe this is the righr way...

Good luck

Hi Pala,

Thank you and it is very informative. Really appreciate your help on this.

the USM (snmpv3) does have following construction:

Configure snmp-user credentials:
#configure snmpv3 add user snmpuser authentication md5 authcred privacy privcred

Add snmp-user to the group:
#configure snmpv3 add group RW user snmpuser sec-model usm

define what the group can do:
#configure snmpv3 ad access RW sec-model usm sec-level priv read-view ViewAll write-view ViewAll notify-view ViewAll

the "ViewAll" can be defined:
#configure snmpv3 add mib-view ViewAll subtree 1.0.0.0/0

in your case:
#configure snmpv3 ad access RW sec-model usm sec-level priv notify-view ViewPortUpDown
#configure snmpv3 add mib-view ViewAll subtree xxxxxx

check what is the OID for the port-up/port-down and replace the xxxxx with your OIDs

the next step will be to configure the snmptrap / inform to be sent with these credentials
