Usage guidelines
The device saves the MAC address table through hash chains. If multiple MAC addresses obtain the
same key through hashing, MAC address hash conflicts occur, and the device cannot learn some of
these MAC addresses. The device will broadcast the traffic destined for the unknown MAC
addresses, which consumes bandwidth and resources.
You can increase the hash bucket size of the MAC address table to reduce MAC address hash
conflicts. A larger hash bucket size requires more system resources. Please set the hash bucket size
appropriately depending on system resources.
The set hash bucket size takes effect at the next startup.
Examples
# Set the hash bucket size of the MAC address table to 8.
<Sysname> system-view
[Sysname] mac-address hash-bucket-size 8
The configuration will take effect at the next reboot. Continue? [Y/N]:y
