Chapter 5 Advanced Configuration SNMP > Views SNMP > Global Parameters Local Engine ID Indicates the local device engine ID. The field value is a hexadecimal string. Each byte in hexadecimal character strings consists of two hexadecimal digits. Each byte can be separated by a period or a colon. The Engine ID must be defined before SNMPv3 is enabled. For standalone devices, select a default Engine ID that is comprised of Enterprise number and the default MAC address. For a stackable system configure the Engine ID, and verify that the Engine ID is unique for the administrative domain. This prevents two devices in a network from having the same Engine ID. 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 SNMP Views provide 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.\ View Name Displays the user-defined views. The options are as follows: •• 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 provided. •• 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. The Add to List button adds the Views configuration to the Views Table at the bottom of the screen. 8-Port 10/100/1000 Gigabit Switch with Webview 47
