Command Manual (For Soliton) – MAC Address Table Management
H3C S3100 Series Ethernet Switches
Description
Use the mac-address max-mac-count command to set the maximum number of MAC
addresses an Ethernet port can learn.
Use the undo mac-address max-mac-count command to cancel the limitation on the
number of MAC addresses an Ethernet port can learn.
By default, the number of MAC addresses an Ethernet port can learn is unlimited.
When you use the mac-address max-mac-count command, the port stops learning
MAC addresses after the number of MAC addresses it learned reaches the value of the
count argument you provided. You can use the undo command to cancel this limit so
that the port can learn MAC addresses without the number limitation. By default, no
number limitation is set to the port for MAC address learning.
To prevent illegal devices from accessing the network through a port, you can configure
static MAC addresses and disable MAC address learning for the port. Thus, only the
packets destined for the configured MAC addresses can be forwarded out the port.
Related commands: mac-address, mac-address timer.
