In our tests, SNMPc was unable to resolve DNS names on our Cisco routers and switches, leaving the mapped devices with names such as "Router9." SNMPc did, however, correctly poll and identify HTTP, FTP, SMTP and telnet ports. SNMPc also lets you configure and manage four additional user-definable ports.
SNMPc's autodiscovery is an untamed beast--if you're not careful it will find any device connected to the Internet by scanning through ARP tables! Even with IP filters set up in the discovery agent options, we still discovered subnets outside of our intended test bed. In our initial discovery, SNMPc even generated a ton of traffic over our firewall, which caught Network Computing senior technology editor and security guru Mike Fratto by surprise.
SNMPc populates the topology map while conducting the discovery. It maps devices graphically, similar to how Unicenter and OpenView do it; device status is represented with various colors and through the current event and history windows. There are eight custom tabs on the bottom of the screen to filter status information of individual devices.
SNMPc includes more than 340 canned MIBs from Cabletron, Cisco, Nortel and 3Com, and the product allows third-party MIBs to be compiled.
Setting threshold and manual alarms is a very straightforward process, as with WhatsUp Gold. Use any integer SNMP variable, apply some Boolean logic, and you're in business. As with CA's product, the Boolean logic is your logic, but unlike CA's product, SNMPc does not provide professional services, so you'll have to bring in a third party if you need help. Configured alerts can be generated by pager/SMS, e-mail, alert console, WAV sound, trap forwarding, executable, ODBC export or API links to other applications, such as Touchpaper Helpdesk.
