SNMP Host Selection Help - Page 2
You specify two things on this page:
- Which community(ies) you want to monitor on this host. Enter them all
in the text box, separated by commas (",").
- 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".
