Hello,
I have a 2970 switch which is trunked to a 6513 distribution. On the trunk, i
have defined the list of
VLANs to pass through to the 2970 however all VLANs are showing up in the
downstream 2970.
6513 is running Native IOS 12.2(17)SXB1 on Sup720. In the older hybrid code
once vlans were
cleared off trunks, it pretty much allowed only the ones not cleared....So not
sure why the native IOS
is doing this differently. If anyone has seen this, appreciate your thoughts.
Thanks
Cheers,Padhu
