Mac-Address Timer - HP 830 Command Reference Manual

Parameters
count: Sets the maximum number of MAC addresses that can be learned on an interface. When the
argument is set to 0, the interface cannot learn MAC addresses. The value range for this argument varies
with devices. For more information, see About the Command References for HP Unified Wired-WLAN
Products.
disable-forwarding: Disables the device from forwarding frames with unknown source MAC addresses
after the number of learned MAC addresses reaches the upper limit. Frames with the source MAC
addresses listed in the MAC address table are forwarded.
Usage guidelines
If the command is executed in interface view, the configuration takes effect on the interface. If the
command is executed in port group view, the configuration takes effect on all interfaces belonging to the
port group.
Examples
# Set the maximum number of MAC addresses that can be learned on Ten-GigabitEthernet 1/0/1 to
600. After this upper limit is reached, frames received with unknown source MAC addresses on the
interface are not forwarded.
