Simon,
There have been a number of detailed discussions on GS on just that
question. I strongly suggest you do a search on snmp or trap.
My basic understanding is this:
Except for Rmon traps, for any traps to be sent to a snmp mgmt station, you
must use the command, snmp-server enable traps, which, by default, enables
all gzillion traps.
What makes this complicated (or flexible, depending on your pt of view) is
that there are a number of ways of skinning this cat.
For example, you don't have to enable all traps. You can list the specific
traps you want enabled on the snmp-server enable trap command.
You also, don't have to send all enabled traps to the mgmt station - you
send specify with the command snmp host which traps to send as long as they
are a subset of the enabled traps.
There's also a gotcha related to a default interface command. I can't
recall the exact nature of this, but it lurks out there in the dark waiting
for unsuspecting ccie candidates just to deprive you of your ccie number.
It has something to do the link-status changing (up or down) and it is sent
whether you want it sent or not unless you disable it under the interface.
Sorry I can't tell you more about this because of my long standing leaky
bucket syndrome.
HTH, Tim

Hi,
I am trying to understand the difference in some SNMP cards, the Cisco
config guide is not that clear.
If I configure the following
snmp-server host 192.168.0.1 public isdn
would it be the same as:
snmp-server host 192.168.0.1 public
snmp-server enable traps isdn
TIA
Simon
