1. Edit /etc/rc.config.d/pcitrconf and specify the parameters for

each interface that is to be enabled. Follow the instructions in the ﬁle

on how to conﬁgure each interface.

Please note that setting incorrect parameters can render your

network inoperable and will prevent the Token Ring link from

connecting to the network. Please exercise caution while modifying

parameters.

Please note the following:

a. Starting with B.11.00.01, the parameter names in pcitrconf

have changed. On B.10.20.00 or later, only new names may be

used. Refer to the following table for a list of old and new names.

Use of the new names is encouraged but the old names will work

during the transition period. Refer to the instructions in the

comment section of the ﬁle.

NOTE Using old names will result in a warning in /etc/rc.log during

each boot.

b. The interface name can be found from lanscan(1M).

c. Not all interfaces need to be conﬁgured, only those that are going

to be used.

d. Either autosense or speed/FDX (full duplex), but not both, can be

speciﬁed. If both are speciﬁed, autosense will override

speed/FDX.

e. Although Token Ring supports an MTU of 18000 bytes for a

speed of 16 Mb/s (and 100 Mb/s), most switches do not go that

high. Switches vary in the amount of buffering provided. Some
