E-8. And because port 1 only accepts tagged frames, any untagged frames
from E-9 will not cross from switch 2 to switch 1.
If you want VLAN 2 to pass frames to and from E-9, you need to configure
the ISL differently. For example, you could change port 1 on both switches
as follows:
In this case, if port 1 receives an untagged frame, it assigns the frame to
VLAN 2; for example, VLAN 2 will be flooded with frames from E-9.
On the other hand, when port 1 transmits a frame from VLAN 2, it removes
the tag. Since all the other ports accept untagged frames, those frames will
flood VLAN 3 on both switches, and VLAN 4 on the originating switch.
To see the menus and steps to configure an ISL, see “Configuring Inter-
Switch Links.”
