Using SNMP

For 200 Series software that includes the SNMP (Simple Network Management Protocol) module, you can configure SNMP groups and users that can manage traps that the SNMP agent generates.

200 Series uses both standard public MIBs for standard functionality and private MIBs that support additional switch functionality. All private MIBs begin with a "-" prefix. The main object for interface configuration is in -SWITCHING-MIB, which is a private MIB. Some interface configurations also involve objects in the public MIB, IF-MIB.

SNMP is enabled by default. The System Description web page, which is the page the displays after a successful login and the show sysinfo command display the information you need to configure an SNMP manager to access the switch.

Any user can connect to the switch using the SNMPv3 protocol, but for authentication and encryption, you need to configure a new user profile. To configure a profile by using the CLI, see the SNMP section in ExtremeSwitching 200 Series: Command Reference Guide.

To configure an SNMPv3 profile by using the web interface, use the following steps:

  1. Select System > Users > Accounts from the navigation menu on the left side of the web interface.
  2. From the Accounts menu, select Add to create a new user.
  3. Enter a new user name in the User Name field.
  4. Enter a new user password in the Password field and then retype it in the Confirm field.

    To use SNMPv3 Authentication for this user, set a password of eight or more alphanumeric characters.

  5. To enable authentication, use the Authentication Protocol menu to select either MD5 (Message-Digest algorithm 5) or SHA for the authentication protocol.
  6. To enable encryption, use the Encryption Protocol menu to select DES for the encryption scheme. Then, enter an encryption code of eight or more alphanumeric characters in the Encryption Key field.
  7. Click Submit.
To access configuration information for SNMPv1 or SNMPv2, click and click the page that contains the information to configure.
