How to configure Cisco Router/Switch for SNMP through IOS CLI
Following lab explains how to configure Cisco Router/Switch for SNMP through IOS CLI.
First, we need to create a Standard Access Control List to identify the SNMP Manager. Here the IP Address of SNMP Manager is 192.168.10.100.
Following Cisco IOS CLI commands can be used to configure a Cisco Router / Swicth for SNMP.
OmniSecuR1#configure terminal OmniSecuR1(config)#access-list 20 permit 192.168.10.100 0.0.0.0 OmniSecuR1(config)#exit OmniSecuR1#
After creating the Standard Access Control List, you can configure the Cisco Router / Switch as shown below for SNMP access. Here the community is "OmniSecuCommunity" and Access List is 20, which we created in previous step. "ro" is used to specify this is a "Read-Only" SNMP access.
OmniSecuR1#configure terminal OmniSecuR1(config)#snmp-server community OmniSecuCommunity ro 20 OmniSecuR1(config)#exit OmniSecuR1#
You may also want to Configure SNMP Traps in Cisco Routers / Switches. SNMP Trap messages are problem indicators sent from SNMP Agent to SNMP Manager. Use the following steps to configure your Cisco Router / Switch for SNMP Traps.
OmniSecuR1#configure terminal OmniSecuR1(config)#snmp-server enable traps OmniSecuR1(config)#snmp-server host 192.168.10.100 OmniSecuCommunity OmniSecuR1(config)#exit OmniSecuR1#
