Other vendor Server:SLA works on SNMP traps
Router is the part of MPLS cloud in which SLA and DMS servers are working from the SNMP traps.
Alarm: CPU utilization of the router was flactuating between 20-55%.
Step1:check all the process of CPU which leading cpu utilzation high by command display cpu
Step2:then find process "agnt" was increasing and check the SNMP statistics by comand disp snmp statistics
Step3:Apply acl on the SNMP by allowing only DMS by comand
SNMP--- Create an simple acl, define permitted hosts and apply to community
rule 0 permit source X.X.X.X wild card mask
snmp-agent community read public acl 3001
snmp-agent community write private acl 3001
it was found that the CPU of the router was falctuating between 20-55% randomly.
It was seen that whenerver CPU was high the proces AGENT
AGNT 20% 0/ 79ae7
was high .
And snmp is responsible for this process.
we have also find in the display snmp statistics that the
"6975568 Messages delivered to the SNMP entity"
packets was very high as compaired to other routers.
please check all the process while handling any CPU related issue.
