SUMMARY: Sun trunking

From: Ravi Channavajhala (

I received just three replies, almost all of them suggesting
that I can not do this with multiple switches. In fact one
interesting suggestion from Jonathon Ross (
is to deploy a switch with redundant passive backplanes and
with multiple supervisor engines. Ifact, my switch is as redundant
as it can get, but the reason for deploying two switches is not
only to guard against the switch failure but also the cable failure
(running from server to switch), in which case the other end of
the trunk running into the second switch can seemlessly operate.
Thanks and have a nice July 4th.
