Just a thought. - Digging through another book towards the light at the end
of the tunnel, I have now added VLAN Trunc Links to my knowledge. That has
brought this question up in my mind, so I would like to hear some feedback
on this subject.
I know that much of this depends on the average frame sizes, so lets say
that I have analyzed my network, and the average frame size is 800. Lets
also say that we are only dealing with Cisco Catalyst switches in this
scenario.
The question is, what would be least resource-waste to use as a trunking
link : ISL or 802.1Q???
The 802.1Q has to break the frame open to modify it, but it adds only 4
bytes to each frame.
The ISL does not have to break the frame open because it simply encapsulates
it into a new one, but it adds 30 bytes to each frame.
Any comments on this?
Thanks,
Ole
