Console(config)#
mac-address-table
hash-algorithm
This command sets the hash table algorithm used by the MAC address table. Use
the no form of the command to reset the algorithm to default.
Syntax
mac-address-table hash-algorithm algorithm
no mac-address-table hash-algorithm
algorithm - select either hash algorithm 0 or 1 - see the command
usage section for a description. (Range 0 or 1)
Default Setting
1
Command Mode
Global Configuration
Command Usage
After assigning the MAC address table hashing algorithm (either 0 or 1), the device
must be rebooted for the new algorithm to take effect.
For algorithm 0: the IGMP snooping multicast IP groups can only set to a maximum
of 64 successive groups.
For algorithm 1: layer 2 entries are subject to collisions when both Source MAC and
VLAN ID are incremental.
Note: The switch L2 hashing performance will be superior when the source
address is random and the VLAN ID is fixed, incremental, or random.
Example
Console(config)#mac-address-table hash-algorithm 0
Success. New hash algorithm will be activated after reboot.
Console(config)#
