SNMP Host Selection Help - Page 2


You specify two things on this page:

  1. Which community(ies) you want to monitor on this host. Enter them all in the text box, separated by commas (",").
  2. The method you wish to use to uniquely identify interfaces on this host. There are several methods available; the admin page itself contains a description of each one. If you try a method and most of the interface "names" it returns for it are blank, try a different one; you cannot collect statistics on interfaces which have a blank interface name. You can still use the "Dynamic" feature if you select the "ifIndex" method... but be aware that if you do, and the SNMP agent changes the interface name-to-number map on you, it won't do a bit of good. :)

Note that using "ifName" is dangerous. This is because it almost always returns identical names for multiple interfaces; e.g., "ATM1/0-atm layer", "ATM1/0.0-atm subif", "ATM1/0-aal5 layer", and "ATM1/0" will all end up with "AT1/0". If you use the same interface name on more than one interface on the same host, all kinds of nasty things will happen that I can't protect against. You've been warned. :)

When done selecting options, click on "Go".
