set mac algorithm
14-22 Logging and Network Management
Mode
Switch command, read‐only.
Example
This example shows how to reset the MAC timeout period to the default value of 300 seconds.
D2(su)->clear mac agetime
set mac algorithm
Use this command to set the MAC algorithm mode, which determines the has mechanism used by
the device when performing Layer 2 lookups on received frames.
Syntax
set mac algorithm {mac-crc16-lowerbits | mac-crc16-upperbits |
mac-crc32-lowerbits | mac-crc32-upperbits}
Parameters
Defaults
The default MAC algorithm is mac‐crc16‐upperbits.
Mode
Switch command, read‐write.
Usage
Each algorithm is optimized for a different spread of MAC addresses. When changing this mode,
the switch will display a warning message and prompt you to restart the device.
The default MAC algorithm is mac‐crc16‐upperbits.
Example
This example sets the hashing algorithm to mac‐crc32‐upperbits.
D2(rw)->set mac algorithm mac-crc32-upperbits
show mac algorithm
This command displays the currently selected MAC algorithm mode.
Syntax
show mac algorithm
mac‐crc16‐lowerbits Select the MAC CRC 16 lower bits algorithm for hashing.
mac‐crc16‐upperbits Select the MAC CRC 16 upper bits algorithm for hashing.
mac‐crc32‐lowerbits Select the MAC CRC 32 lower bits algorithm for hashing.
mac‐crc32‐upperbits Select the MAC CRC 32 upper bits algorithm for hashing.
