Usage guidelines If ports on different IRF member devices are selected ports from the same aggregation group, MAC address entries are synchronized among these IRF member devices regardless of whether MAC address synchronization is enabled for the IRF fabric. For more information about aggregation groups, see Layer 2-LAN Switching Configuration Guide. The MAC address table size might vary with different IRF member devices. With MAC address synchronization enabled, MAC address entries exceeding the table size of an IRF member device cannot be synchronized to the MAC address table. Examples # Enable MAC address synchronization. system-view [Sysname] mac-address mac-roaming enable mac-address max-mac-count Use mac-address max-mac-count to configure the maximum number of MAC addresses that can be learned on an interface. Use mac-address max-mac-count enable-forwarding to enable the device to forward frames with unknown source MAC addresses after the number of learned MAC addresses reaches the upper limit. Use undo mac-address max-mac-count to restore the default maximum number of MAC addresses that can be learned on an interface. Use undo mac-address max-mac-count enable-forwarding to disable 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. Syntax mac-address max-mac-count { count | enable-forwarding } undo mac-address max-mac-count [ enable-forwarding ] Default The maximum number of MAC addresses that can be learned on an interface is not configured. When the upper limit is reached, the received frames are forwarded. Views Ethernet interface view Predefined user roles network-admin Parameters count: Sets the maximum number of MAC addresses that can be learned on an interface. The value range is 0 to 4096. When the argument takes 0, the interface is not allowed to learn MAC addresses. enable-forwarding: Enables the device to forward frames with unknown source MAC addresses after the number of learned MAC addresses reaches the upper limit. Frames that have the source MAC addresses listed in the MAC address table are forwarded. 57

Usage guidelines
If ports on different IRF member devices are selected ports from the same aggregation group, MAC
address entries are synchronized among these IRF member devices regardless of whether MAC address
synchronization is enabled for the IRF fabric. For more information about aggregation groups, see
Layer
2—LAN Switching Configuration Guide
.
The MAC address table size might vary with different IRF member devices. With MAC address
synchronization enabled, MAC address entries exceeding the table size of an IRF member device cannot
be synchronized to the MAC address table.
Examples
# Enable MAC address synchronization.
<Sysname> system-view
[Sysname] mac-address mac-roaming enable
mac-address max-mac-count
Use
mac-address max-mac-count
to configure the maximum number of MAC addresses that can be
learned on an interface.
Use
mac-address max-mac-count enable-forwarding
to enable the device to forward frames with
unknown source MAC addresses after the number of learned MAC addresses reaches the upper limit.
Use
undo mac-address max-mac-count
to restore the default maximum number of MAC addresses that
can be learned on an interface.
Use
undo mac-address max-mac-count enable-forwarding
to disable 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.
Syntax
mac-address max-mac-count
{
count
|
enable-forwarding
}
undo mac-address max-mac-count
[
enable-forwarding
]
Default
The maximum number of MAC addresses that can be learned on an interface is not configured. When
the upper limit is reached, the received frames are forwarded.
Views
Ethernet interface view
Predefined user roles
network-admin
Parameters
count
: Sets the maximum number of MAC addresses that can be learned on an interface. The value
range is 0 to 4096. When the argument takes 0, the interface is not allowed to learn MAC addresses.
enable-forwarding
: Enables the device to forward frames with unknown source MAC addresses after the
number of learned MAC addresses reaches the upper limit. Frames that have the source MAC addresses
listed in the MAC address table are forwarded.
