A VNE must be loaded into the bootstrap of the Sheer DNA Unit before it
starts monitoring its underlying NE. This changes the administrative status of
the VNE to Up, and ensures that the VNE is loaded on subsequent restarts of
the Sheer DNA Unit. Loading the VNE also starts the VNE immediately. For
more information on the status of VNEs, refer to page 88.
Before adding a new VNE using DNA Manage, the user must first determine
to which Sheer DNA Unit and AVM, the new VNE should be added.
The user can define and manage SNMP, Telnet/SHH, ICMP, and polling
information for the appropriate VNEs in the New VNE dialog box.
Note: A new VNE cannot be added to the reserved AVMs 0-100.
The user can create VNEs that perform reachability testing only through
ICMP. This can be done by creating the VNE and selecting the type ICMP
and then defining the details in the ICMP tab. For more information about
the ICMP tab, refer to page 98.
For information on defining VNE properties in the respective VNE tabs, refer
to the following sub-sections:
• General properties on page 92
• SNMP properties on page 94
• Telnet/SSH properties on page 96
• ICMP properties on page 98
• Polling properties on page 99
For details on viewing and editing VNE properties, refer to the section
Viewing and Editing a VNE’s Properties on page 101.
To define the properties of a new VNE
1. Select the DNA Servers branch in the Sheer DNA Manage window’s
Tree pane. The DNA Servers branch is displayed.
2. Expand the DNA Unit branch and select the required AVM sub-branch in
the Tree pane.
