| Hello!
Does anybody know, which trunk-methods allow a spanning-tree instance per
VLAN???
a.) ISL
b.)802.1q
c.)both
c.) is correct. From my point of view a.) is correct, because 802.1q support
a spanning-tree instance for all VLANs. (There are different descriptionn in
e-books).
Thanks for comments
