Review: SolarWinds Sheds Light on Networks: Page 4 of 19

The IP Address Management tool tracks addresses and determines whether they are being used, when they were last used, if they are available and response time to pings. For devices supporting SNMP, machine, type, name and location are also displayed.

The Subnet Calculator, besides doing the obvious, queries a host to determine its running mask. Guess what the MIB Browser does? Right: It performs table and specific OID (object identifier) gets, with textual explanations. MIB queries can be loaded into separate windows, making comparison easier. But, alas, there's no set access and no MIB compiler. Actually, a separate and included tool, Update System MIB, will change system name, location and contact fields. SolarWinds plans on adding a compiler in a future release.

The MIB Walker is nice, performing get nexts until the MIBs supported by a device are completely discovered. Be careful though--not only can this take more than a couple of minutes, we have seen it drive up CPU utilization. SolarWinds offers a good, not great, MIB browser (Castle Rock's SNMPc has the best MIB browser).

SolarWinds is the only product we tested to include router and switch configuration management; we downloaded and stored Cisco configurations. Also included is a differing application that will check what's stored against what is running. A TFTP server is also provided, to allow for upload of router and switch images and configurations.

The Traffic Generator, as its name suggests, generates random traffic, with variable packet size and either automatic interframe gap or user-selectable interframe gap. From your laptop you aren't going to bring the network down, but you'll do some damage (not that we ever have).
