Dear Dayong,
Yes, Token ring switch is very much there in the lab.
Hope following info is useful for you.
Here is some tips on Catalyst 3920 TokenRing Switch:
1) According to the configuration guide, with default configuration the
switch
is supposed to be autosensing speed and duplex mode of the conncetd routers.
That is if you really don't want more than one vlan in your network the
switch
installation is supposed to be plug and play.
But this is not the case in reality. For some cisco router models like
Cisco4500 it deos not detect the duplex mode properly. Infact a half duplex
attached router port it detects as a full duplex one. Remedy is go to port
configuration mode and ensure that the duplex mode is properly detected,
otherwise set it manually from there.
2)To creat a couple of TokenRing VLANS two emulate two tokenrings, one don't
need to be bothered about the bridging modes and STP modes , the default
should work. The shorest way to creat two vlans is to exactly follow the
tutorial whose link is given below. Again check and make sure your duplex
mode:

Hi, All.
I just found that 3900 series token ring switches is on the LAB test
equipment list. Does anyone know we need to config the switch or not?
