Max Explorer Rate
Sets the maximum explorer frame rate. If enabled, this will limit the amount of
explorer frames being forwarded from the HSTR side of the virtual port to the
switch.
Range: 0 to 5000 frame/sec or Disabled
Default: Disabled .
VLAN Tagging Mode
Sets the VLAN tagging mode of the virtual port. As explained previously, one
virtual port on each HSTR port can be untagged. All other virtual ports must be
tagged and each of these virtual ports must use a unique 802.1Q VLAN ID with the
same physical port. The 802.1Q VLAN ID can be configured for the TrBRF
configurations. Please refer to the CrossFire 8600/8605 Token-Ring Switches
Guide to Operation for further information. When configuring the Tagging mode
and the 802.1Q VLAN ID, make sure that the same Tagging mode and 802.1Q
VLAN is used at both ends.
Preferably, the VLAN which is expected to have the largest amount of traffic
should be untagged, since VLAN tagging does impose a small overhead.
Default: Untagged. (first virtual port)
Default: Tagged. (following ports)
FC Modification
Enables or disables FC modification when a frame tag is removed, possible values
are Enabled and Disabled. As discussed earlier a VLAN frame tag also contains a
3 bit priority field. If FC modification is enabled, the Token-Ring frame priority in
the FC byte is overwritten with the frame tag priority, if the frame tag priority is not
equal to zero. If FC modification is disabled, the FC priority is left as it is, and the
frame tag priority is discarded.
When the CrossFire 8650 or 8651 UEM inserts a frame tag in a frame, it always
uses the FC priority as the frame tag priority, so for frames received from another
module, this option makes no difference. Other devices, however, might require
that the frame tag priority should take precedence, in which case FC modification
should be enabled.
Default: Disabled .
