The SNMP Tools Screen

This section describes specific commands and features within the
SNMP Tools screen. This screen allows you to access management
information bases (MIBs), and varies according to your level of
security access.

The following descriptions outline the super-user management
capabilities. From SNMP Tools you can:

•

review specifics about object identifiers (OIDs)

•

edit configurable OIDs

•

view OIDs sequentially from the originally requested OID.

To access the SNMP Tools Screen from the Features Selection Screen,
use the arrow keys to highlight the SNMP Tool Support option, then
press the Return key. The SNMP Tools Screen, Figure 5-12, appears.
