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,
