CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Switch Configuration
Status
This field is for informational purposes only, and shows if the port is currently
inserted into the ring.
Media Type
This field is for informational purposes only, and shows the media type of the port.
Possible values are
RJ-45
,
ST Fiber
, and
VF-45
.
Media Speed
The Token-Ring media speed. Possibilities are
4
or
16 Mbps
or
Auto
. When a
switch port configured with
Auto
discovers a connection to shared media, it will
open and insert into the ring. If the open returns with an indication, that the port is
the first station to enter the ring, it will close.
This algorithm is analogue to that of auto-sensing adapters, which dictates that an
adapter, which is capable of speed adjustment, must have some other station on the
ring (typically a server), from which it can sense the network speed.
If you want to have switch ports, which are attached to shared media, it is
recommended that you change the default media speed configuration from
Auto
to
either
16
or
4 Mbps
.
Max Explorer Rate on Input
The maximum Explorer frame forwarding rate per second. Possible values are
Disabled
(default) or
0
-
5000
.
MTU
The
Maximum Transfer Unit
is the size of the information field of packets to be
sent or received. Possible values are
1,500
and
4,472
(default),
8,144
, and
17,800
.
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 on page 55.
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
Ye s
and
No
. The default is
Ye s
. If
Early Token Release
is set to
Ye s
and the media speed
is 4 Mbps, the switch will force
Early Token Release
to
No.
