Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include cable modems, routers, switches, servers, workstations, printers, and more.
How do I configure SNMP V2 on Cisco Catalyst 2960x including ACL (Access list):
ACL – we creating an access list that only permits to specific IP to collect SNMP data.
- 192.168.10.X allowed to only use snmp to read data from the devices. RO (Read only Mode)
- 192.168.9.X allowed can also read the data from the devices and also write to the devices. RW ( Read and Write)
access-list 5 permit 192.168.10.X
access-list 5 permit 192.168.9.X
access-list 5 deny any
snmp-server community “Password1” RO 5
snmp-server community “Password2” RW 5
snmp-server enable traps snmp linkdown linkup
snmp-server host 192.168.10.X version 2c “Password1”
snmp-server host 192.168.9.X version 2c “Password2”
Monitor system collect data like Temp, Cpu, Memory using SNMP protocol from devices and present us the information in a readable and easy way.
