Configuring SNMP - WebUI

To enable SNMP:

1. In the tree view, click System Management > SNMP.
2. Select Enable SNMP Agent.
3. In Version drop down list, select the version of SNMP to run:
   • 1/v2/v3 (any)

     Select this option if your management station does not support SNMPv3.

   • v3-Only

     Select this option if your management station supports v3. SNMPv3 provides a higher level of security than v1 or v2.

4. In SNMP Location String, enter a string that contains the location for the system. The maximum length for the string is 128 characters. That includes letters, numbers, spaces, special characters. For example: Bldg 1, Floor 3, WAN Lab, Fast Networks, Speedy, CA
5. In SNMP Contact String, enter a string that contains the contact information for the device. The maximum length for the string is 128 characters. That includes letters, numbers, spaces, special characters. For example: John Doe, Network Administrator, (111) 222‑3333
6. Click Apply.

2. Select the header row checkbox to select all or select individual interfaces.

To configure the community strings:

1. In the V1/V2 Settings section, in Read Only Community String, set a string other than public. This is a basic security precaution that you must always use.
