Hello Alan,
We have purposefully configured these routers to send snmp traps (up/down/coldstart/conf change etc.) to our NetView server and these traps are processed for some actions. So, stopping these routers to send snmp traps will affect our monitoring objectives.
I wanted to know, what could be the reason for " PPP LCP Closed" error message. Are our routers configured wrongly OR these errors shows that links are unstable.
This link is of multilink concept and 5 links of 2 mbps pipe is grouped together to give 10mbps output. Obviously, all these five links are configured on the same interface of the router and these links does not have different IP address.
Regards,
Anupam

You most likely have the following configuration on your router
!
! Host to send traps to
!
snmp-server host your_trap_processing_host
!
! Send SNMP traps, notice linkdown and linkup
! This can sometimes depending on the IOS version look like this
!
! snmp-server enable traps snmp
!
snmp-server enable traps snmp authentication linkdown linkup coldstart
warmstart
The solution is to
1. Disable sending SNMP traps. This will stop all authentication, linkdown,
linkup, coldstart and warmstart traps
no snmp-server enable traps snmp
2. Disable a particular interface from sending traps
interface replace_with_your_interface
no snmp trap link-status
Thanks

Hello,
We are having NetView 6.0.2 on AIX 4.3.3
From one cisco router, we are continuously receiving the following kind of
traps saying 'PPP LCP closed" :-
1059222261 11 Sat Jul 26 18:54:21 2003 CORT3 A Cisco Agent Interface Down
(linkDown Trap) on interface: Serial3/1:0 locIfReason: PPP LCP Closed
1059222279 11 Sat Jul 26 18:54:39 2003 CORT3 A Cisco Agent Interface Up
(linkUp Trap) on interface: Serial3/2:0 locIfReason: PPP LCP Open
What could be the problem with the router or its configuration? Where
should I look into?
Regards,
Anupam Kr Anand
