# Create an SNMP Agent for SNMP version 1 or 2c

Configure an SNMP Agent for SNMP version 1 or 2c so that Security Engines can share network management information using the SNMP protocol, or for SNMP version 2c so that the SMC Appliance can share network management information using the SNMP protocol.

##

Note: The SMC Appliance does not support SNMP v1.

For more details about the product and how to configure features, click Help or press F1.

## Steps

1. Select Engine.

   For the SMC Appliance, you must select v2c.
6. (Optional) In the Monitoring section, click Add, then enter the community string.
   The community string is used for authentication in monitoring.
7. (Optional) In the Listening Port field, enter the UDP port number that the SNMP agent listens to.
8. In the Contact field, enter the contact information for the person responsible for the Security Engines or the SMC Appliance.
9. Click OK.
