Hi Sir,
I have a Cisco AS5300 access server (IOS 12.0(7)T) which is configured to send SNMP traps. The SNMP trap global config commands are as follows:
!
snmp-server trap-source Loopback0
snmp-server enable traps snmp
snmp-server host 10.10.10.10 cisco123 snmp
!
The command "snmp-server enable traps snmp" does not have the optional keywords "linkup" or "linkdown".
All the Serialx:15, Group-Async, and Dialer interfaces are configured with the command "no snmp trap link-status".
However the NMS staff still claim that they receive SNMP traps from this router whenever remote users dial in and disconnect.
What's the workaround to prevent the router from sending SNMP traps for linkup/linkdown condition? I was under the impression that the interface config command "no snmp trap link-status" should fix the problem.
Please advise.
Thank you.
B.Rgds,

Hi Sir,
What's the relationship between the notification types in the "snmp-server enable traps" command and the notification types in the "snmp-server host" command?
E.g.
Scenario 1
----------
snmp-server enable traps bgp
snmp-server host 10.10.10.10 cisco123 hsrp
Scenario 2
----------
snmp-server enable traps bgp
snmp-server host 10.10.10.10 cisco123 snmp
Scenario 3
----------
snmp-server enable traps bgp
snmp-server host 10.10.10.10 cisco123
In Scenario 1, no HSRP notification is sent to host 10.10.10.10 because globally only BGP notification is enabled. Am I right?
I don't understand Scenario 2.
In Scenario 3, the router will sent all notification types but is limited to BGP. Am I right?
Thank you.

In scenario 1 and 2, no traps should be send to the host configured. If you have only enabled bgp traps in both instances nothing will be sent.
In scenario 3 bgp traps will be sent
