Netdump over bonded interface ?

Netdump over bonded interface ?
Hey there,..
I have heard from admins, that netdump usually fails over a bonded network interface.

I have written a multi-OS checkdump script , which checks if the respective crashdump utility on corresponding OS is correctly configured, space is available, etc etc etc.

For the netdump check, I wanted to add in a check to see if netdump is using bonded interface . How do I do that ? I can easily find out if the system has bonding enabled or if bond0 is up or down .
But I want to know if Netdump is going to use this bonded interface to send out the dump, or the usual interface ?

/etc/sysconfig/netdump doesnt give much of an idea. Does LOCALPORT setting have something to do with it ? It defaults to 6666.
I have minimal understanding about the networking side of this problem, could some one please tell me :
1. How do I find out which network interface (outgoing) netdump is currently configured to use ? How to check if its bonded or not ??

2. I also wanted to do a ethtool $NIC to check if the ethernet link is
down or up, so this brings back to finding out which network interface is used by netdump , eth0 , eth1 , bond0 ??? How can I find this out.

avahi-autoipd.action - avahi-autoipd action script SYNOPSIS
/home/lennart/tmp/avahi/etc/avahi/avahi-autoipd.action DESCRIPTION
avahi-autoipd.action is the action script that is called whenever an IP address has been acquired by avahi-autoipd or when it detected an IP address conflict. The script should add or remove the specified address from the specified network interface. PARAMETERS
argv[1] An event string: one of BIND, CONFLICT, UNBIND or STOP. If BIND is passed an IP address has been successfully acquired and the script shall add it to the network interface. If CONFLICT is passed avahi-autopid detected a IP address on the local network, the action script should remove the configured IP address. If UNBIND is passed the IP address should be removed from the interface, too, because a routable address has been configured to the interface by some other program. If STOP is passed the avahi-autoipd is being shutdown and the action script should remove the IP address. In short: on BIND the address should be added to the interface, on CONFLICT, UNBIND or STOP it should be removed. argv[2] The network interface name. argv[3] An IP address from the IPv4LL range.
