Max Bridge Transmit Delay Bound
This control is used in association with QoS Configuration to control the time that packets
may be queued in the Switch. If the packet is stored in the Switch for a time exceeding the
specified amount, then it is dropped. These settings do not need to be changed except for
networks where time-sensitive prioritized traffic is used. The default is OFF.
Low Queue Delay Bound
If low priority packets are queued in the Switch for longer than the ‘Low Queue Max Delay
Time’, then the Switch will forward the packet immediately. Default is Disable.
NOTE: Ensure that ‘Max Bridge Transmit Delay Bound’ is ON before enabling ‘Low Queue
Delay Bound’.
Low Queue Max Delay Time
Defines the maximum time a low priority packet will be queued before being sent. The valid
range is 1 to 255ms. The default max delay time is 255ms.
Collisions Retry Forever
In the default enable state the Switch will attempt to send a packet forever in the event of
collisions. If disabled the Switch will re-transmit the packet up to 48 times in the event of
collisions and after this the packet will be dropped.
Hash Algorithm
This controls the method used to maintain the MAC table. Either CRC Hash or Direct Hash.
The default is CRC Hash.
IFG Compensation
When enabled Inter-Frame Gap is forced to 0.96 microseconds. This maintains compatibility
with LAN cards and other network equipment. If disabled then the IFG remains unchanged.
The default is enabled.
IP Stacking Group ID
Assigns the stacking group ID, which is used to control stack membership. Switches
belonging to the same stack must be assigned the same stacking group ID. The valid range is
0 to 65535).
IP Stacking Mode
There are three stacking modes that can be configured on the Switch:
• Disable – The Switch is not participating in a stack and is standalone (default)
• Master – The Switch is the main controller Switch in the stack. There can be only one
configured Master in the stack.
• Slave – All other Switches in the stack are configured as Slaves. Web management
of these Slave Switches is preformed via the Master Switch.
IP Stacking System Information
This is a meaningful name that can be given to the Switch e.g. Sales Switch – rack 4, that is
displayed when using a web browser to manage the Switch.
Please refer to page 42 for further details about Stacking.
