Yes. There is only a an exception to point 1:
The 'snmp-server enable traps' is not required for traps which are sent
using a different command. For example the 'SNMP trap link-status'
interface command would send traps to specified hosts even if the
'snmp-server enable traps' command is not configured.

Yasser

Ah, Yasser, that was the missing piece of info.
Thank you, man.
I bet you must work with snmp at your job, right?
Now, one last variation I'd like to ask you about. Suppose this were
the
config:
snmp-server host 10.10.10.10 public config bgp tty
snmp-server enable traps
According to the Doc's, if no type of trap is specified, then, by
default,
all traps can be sent, correct?
But, since the snmp-server host specified 3 particular traps, only those
traps are sent to only that host.
Then to summerize how these commands work:
1) To send traps both the snmp-server host command and the snmp-server
enable trap MUST BE SPECIFIED.
2) If specific traps are listed in the snmp-server host command, that
host
will get only the traps specified in that command
3) If specific traps are specified in the snmp-server enable trap
command,
those traps will be sent to all hosts specified in all snmp-server hosts
commands which DON'T have specific traps listed. For example,
snmp-server host 11.11.11.11 public
snmp-server host 10.10.10.10 public config bgp tty
snmp-server enable traps hsrp
Here, host 11.11.11.11 will get the hsrp trap because it didn't specify
any
traps and
host 10.10.10.10 wil get the config bgp and tty traps because those are
the
traps its specified.
Do you this right?
Thanks, Tim
