through the fog of time what one thought once inalienable, becomes muted...
back to the beginning again...
recent events have me reevaluating...
what is a trunk and what makes an etherchannel so very different...
from: http://www.ciscopress.com/articles/article.asp?p=29803&seqNum=3
A trunk port is by default a member of all
the VLANs that exist on the switch and carry traffic for all those VLANs between
the switches. To distinguish between the traffic flows, a trunk port must mark
the frames with special tags as they pass between the switches. Trunking is a
function that must be enabled on both sides of a link. If two switches are
connected together, for example, both switch ports must be configured for
trunking, and they must both be configured with the same tagging mechanism (ISL
or 802.1Q).
good... an etherchannel does the same thing only it allows for the aggregation of ports into a bundle, thus increasing the total bandwidth available by a factor of the included ports...
from: http://en.wikipedia.org/wiki/EtherChannel
EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches. It allows grouping of several physical Ethernet
links to create one logical Ethernet link for the purpose of providing
fault-tolerance and high-speed links between switches, routers and
servers. An EtherChannel can be created from between two and eight
active Fast, Gigabit or 10-Gigabit Ethernet ports,
with an additional one to eight inactive (failover) ports which become
active as the other active ports fail. EtherChannel is primarily used in
the backbone network, but can also be used to connect end user machines.
