Publication Date:  2012-09-14 Views:  346 Downloads:  0
Issue Description
network manager cannot receive network element alarm
Alarm Information
Handling Process
1. Check whether network element has configured SNMP parameter successfully.
(1) Perform the command "display current-configuration | include snmp" in the network element side.
display current-configuration | include snmp
15:38:59  2011/05/03
snmp-agent community read   public
snmp-agent community write   private
snmp-agent sys-info version v2c
snmp-agent target-host trap address udp-domain params securityname public v2c
snmp-agent trap enable bgp
snmp-agent trap enable lsp
snmp-agent trap enable ldp
snmp-agent trap enable system
snmp-agent trap enable standard
snmp-agent trap enable mstp
snmp-agent trap enable vrrp
snmp-agent trap enable ssh
snmp-agent trap enable flash
snmp-agent trap enable srm
snmp-agent trap source GigabitEthernet0/0/0

(2) Check whether IP address “” of destination host computer is IP address of network manager server, whether the safe name “public” is same with reading community string.
(3) Check whether the trap function is enabled
(4) Check whether the source interface “GigabitEthernet0/0/0” sending trap is management interface registered by network element on VSM.

2. Check whether network management server has received the alarm.
(1) Check whether it can ping between network management server and the network element, repair the net connection if it cannot ping each other.
(2) Check whether it can receive the SNMP trap packets coming from network element by using packets capturing soft on network element.

3. Check whether network management configuration is right.
(1) Check whether network management side SNMP parameter is identical with network element side parameter.
(2) Choose “failure> setting>screen rules” on VSM client-side, check whether the alarm is screened in “screen rules” window.
(3) Login VSM system to monitor the client-side, check whether “trap distributer” and “trap receiver” process are start normally.
