[c-nsp] VLAN Trunking from Netgear GS748T to Catalyst 1924EN

[Skeeve Stevens]

Hey Steve,

	Thanks for this.. I've learnt something... And I feel stupid I
didn't realise.

	Question.  I have a spare 3524XL lying around.  Could I use this to
bridge between the two? I assume the 3524XL does ISL and dot1q trunk... I
also have a 2950-24 as well.. Could this be useful as well?

...Skeeve

This will not work.  The Cat1900 is ancient and only supports ISL trunk
encapsulation.  I know nothing about the Netgear but I'm sure it only
supports 802.1q trunk encapsulation, so you are out of luck.

They are not on crack, link aggregation is (unfortunately) also referred to
as trunking - it's ambiguous terminology.
