ISPPlanet NMS Series - Castle Rock SNMPc

Device Control

SNMP SET can modify device parameters when permitted by the MIB and authorized by the community string. SETs performed through the SNMPc MIB Browser (below, left) offer little in the way of error handling. Most admins will prefer using Tool Menus to modify objects using MIB-specific Table Edit or Table Set commands. Table Edit (below, right) provides the most detail; an expanded view panel describes the variable and its object identifier, syntax, and current value.

Table Set (right) highlights write-able variables, although a valid community string is of course required for successful update. When supported by the agent, SNMP SET interfaces make it possible to remotely reconfigure devices—in this example, (re)enabling a router port by setting ifAdminStatus up.

But many device updates cannot be performed through SNMP. To this end, SNMPc device menu items include Telnet and Web Browser—clients typically used to make updates using a device-specific CLI or GUI. SNMPc also includes TFTP and BOOTP servers—software frequently used to upload (and download) device config files.
