VLAN Tagging Mode
Sets the VLAN tagging mode of the virtual port; possible values are Tagged and
Untagged. As explained previously, only one virtual port on each TS port can be
untagged. All other virtual ports must be tagged and the 802.1Q VLAN ID must be
the same in both ends.
Because VLAN tagging mode imposes a small overhead, the VLAN that is
expected to have the largest amount of traffic should be untagged.
Default: Untagged for the first virtual port and Tagged for the subsequent ports.
FC Modification
Enabled FC modification preserves frame priority during translation between
Ethernet and Token Ring (both directions). 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 set to the frame tag priority. If FC modification is disabled, the FC priority is set
to 0, and the frame tag priority is discarded.
When the SSIM-H2-02 inserts a frame tag in a frame, and FC modification is
enabled, the SmartStack SSIM-H2-02 module uses the FC priority from the Token
Ring frame. Otherwise the frame tag priority is set to 0 and the FC priority is
discarded.
Default: Disabled
Address Aging Time
Sets the aging time for addresses and RIFs learned on an TS port. Possible value
are 1 to 9999 minutes or 0 to disable aging. When there has been no activity on an
address it is deleted from the address table.
For an address using the RIF entry, when no frames with the RIF have been
received for the specified period of time, the RIF and address entry is deleted. Only
for address entries known from the host is the status of the address changed to RIF
unknown.
Default: 5 minutes
RIF Not Learn Interval
Sets the learning blocked interval for RIF entries. Possible values are 0 to 900
seconds. A new RIF cannot be learned unless a specified period of time has passed
since the activity on current RIF entry was seen.
Default: 20 seconds
