CrossFire 8730 Switch Reference Guide, DOC-7047 v. 1.1 Switch Configuration
The actual value used depends also on the value configured for the TrBRF (the
smaller value is used).
These values correspond to maximum frame size values of 1,548, 4,546 (default),
9,236, and 18,192 respectively.

Note: See the description on frame length limit in the
CrossFire 8730 Fast Ethernet
Translation Switch Installation Guide.
Force AC Bits on SR Frames
This field specifies if AC bits will be set unconditionally when a port forwards
certain LLC frames. Possible values are Yes and No (default).
Early Token Release
Whether the port is enabled for Early Token Release (ETR). Possible values are Yes
and No. The default is Yes. If Early Token Release is set to Yes and the media speed
is 4 Mbps, the switch will force Early Token Release to No.
Operation Mode
The Token-Ring port operation mode. Possible values are as follows:
•
Auto (default. Only HDX and FDX modes can be automatically detected.)
•
HDX port
•
HDX station
•
FDX port
•
FDX station
•
RI/RO
Only on ports 19 and 20.
•
Passive
(this value is not user-selectable, and will be displayed if the port has been
selected as a passive monitoring port on the Switched Port Analyzer screen).
Forwarding Mode
Forwarding mode that will be used to transmit frames. Possible values are auto, cut-
through, and store & forward. The default is auto. If the forwarding mode is set to
auto, the actual mode will depend on the number of errors that occur during the
sampling interval. If the error rate is below the error low threshold, then cut-through
mode is used. If the error rate is above the error high threshold, then store & forward
is used. The store & forward mode is always used for Token-Ring ports with a
media speed of 4 Mbps and for teh Fast Ethernet ports.
