Subject: Multiport NICs and ether channel?

Greetings,

Just a general question or two.. Please point me to a URL or tell me where
to RTFM, or answer back ;-).

What is the status/condition of using muliport NICs and bonding
them together to form a larger pipe (i.e. a quad channel ethernet card for
an Intel box, bonding all four interfaces together to get a theoretical
400Mbps pipe)? Are there any highly recommended cards of this type? Will
the bonding work when connected to a Cisco catalyst switch with ether
channel?

Again, thanks in advance. If you need any further info, or if I need to
describe something in greater detail please let me know.

Cheers,
Will Sarka

Linux bonding is compat with Sun EtherTrunking and Cisco
EtherChannel/FastEtherChannel.


On the Cisco side you follow their setup examples, *except*
you *must* trun keepalives off on the cisco. These are a Cisco
extension. If you fail to do this the Cisco will toggle the
onterfaces *off* every 10 - 30 seconds.
