Hello I am trying to figure out how to trunk between a catalyst 2950 and a 1900 ..I've either overlooked something in my book or else am missing the whole thing..any and all help greatly appreciated..
The 2950 switch only does 802.1Q trunking. The 1900 switch only does ISL trunking
(supports up to two Fast Ethernet ISL trunks, does not support 802.1Q) so we cannot trunk
directly between the 2950 and the 1900 switch.
Unfortunately, there is no configuration
that we can do to make them "trunk". The only way to implement vlan mangement between
these two platforms is by physically
connecting links equal to the number of vlan's configured on the switches to carry
different vlan traffic. Obviously, this could only be a workaround and not very scalable
due to physical port limitation.
Note : If that helps then please mark this thread as solved, so that others can benefit from it.
