SSIM-R2-02/SSIM-R8-02 HSTR SmartStack Interface Modules Installation and User Guide
Console Configuration
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 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 TrBRE
configuration. Refer to the SmartStack STS16-20RM Token Ring Installation and
User Guide. When configuring the Tagging mode and the 802.1Q VLAN ID, make
sure that the same Tagging mode and 802.1Q VLANs are 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 SSIM-Rx-02 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.
Address Aging Time
Sets the aging time for addresses learned on an HSTR port. When there has been
no activity on an address for the specified period of time it is deleted from the
address tables.
Range 1 to 9999 minutes or 0 (for disabled).
Default: 5 minutes.
