Set Mac Algorithm; Show Mac Algorithm - Enterasys SECURESTACK C3 Configuration Manual

Mode
Switch command, read‐only.
Example
This example shows how to reset the MAC timeout period to the default value of 300 seconds.
C3(su)->clear mac agetime

set mac algorithm

Use this command to set the MAC algorithm mode, which determines the hash 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
mac‐crc16‐lowerbits
mac‐crc16‐upperbits
mac‐crc32‐lowerbits
mac‐crc32‐upperbits
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.
C3(rw)->set mac algorithm mac-crc32-upperbits

show mac algorithm

This command displays the currently selected MAC algorithm mode.
Syntax
