As you can see, the single-dual field is preset to single and the optical-bypass
is preset to off. The following sets the FDDI interface 0 to DAS and saves the
new settings:
super> set single-dual = dual
super> cd ..
port_num = 0
cisco-hdlc = { off on 10 3 }
fddi = { dual off }
sonet = { "" "" 1 sonet internal-oscillator 0 207 }

You have to go through the same procedure again and replace references to
port 0 with port 1.
Use
sh to return to the operating system of the GRF and grreset the card, or
use
exit to log off from the router.
Once you get more familiar with the GRF, you may prefer the following quick
way:
super> read card 0
CARD/0 read
super> set port 0 fddi single-dual = dual
super> set port 1 fddi single-dual = dual
