you understood correctly.About the  bills to be generated the customer does not
care as is a PPT. They want to ping the ethernet interface of router2 for two
1. know the status, so the have visibility of router on NetView interface
2. test the isdn line between.

I convinced the customer to set different polling intervals and I will let you

My customer have a lot of branches with the following configuration:
In each branch there  are two routers,  the Router 2 has two interface:
ethernet and isdn. In the POP there is a router who   receive the isdn
from a lot of branch routers but supports (at the same time) up to 30 isdn
The network is managing by NetView AIX 5.1.1. Router 2 has the isdn
unmanaged and managed just the ethernet interface. Router 2 (according to
configuration) when receive a pachet in the ethernet interface route this
through the isdn interface .  NetView ping for status information the
interface of  Router 2  in the branches (there are more  than 30) but   the
Router 3 cannot manage all these isdn calls so the Router 2 appears in the
NetView submap  in critical status BUT if you ping  it after a while the
will report the status correctly.
I am wondering if can "customize" the netmon ping (maintain the ping
in such way that won't ping  "at the same  time" all the ethernet interface
all Router 2.
Any idea or hint ?.
Thanks a lot.
