Chapter 5 Configuration Using the Web-based Utility

Use Default  Uses the device generated Engine ID. The default Engine ID is based on the device MAC address and is defined per standard as:

•First 4 octets  First bit = 1, the rest is IANA Enterprise number.

•Fifth octet  Set to 3 to indicate the MAC address that follows.

•Last 6 octets  MAC address of the device.

SNMP Notifications  Indicates if the device can send SNMP notifications.

Authentication Notifications  Indicates if SNMP Authentication failure notification is enabled on the device.

SNMP > Views

The SNMP Views screen provides access or block access to device features or feature aspects. For example, a view can be defined that states that SNMP Group A has Read Only (R/O) access to Multicast groups, while SNMP Group B has Read-Write (R/W) access to Multicast groups. Feature access is granted via the MIB name, or MIB Object ID.

SNMP > Views

•Default  Displays the default SNMP view for read and read/write views.

•DefaultSuper  Displays the default SNMP view for administrator views.

Subtree IDTree  Indicates the device feature OID included or excluded in the selected SNMP view. The options to select the Subtree are as follows:

•Select from List  Select the Subtree from the list.

•Insert  Enables a Subtree not included in the Select from List field to be entered.

View Type  Indicates if the defined OID branch will be included or excluded in the selected SNMP view.

Click Add to List to add the Views configuration to the Views Table at the bottom of the screen.
