Description
Use the mac-address information queue-length command to set the MAC Information queue
length.
Use the undo mac-address information queue-length command to restore the default.
By default, the MAC Information queue length is 50.
Setting the MAC Information queue length to 0 indicates that the device sends a Syslog or trap
message to the network management device as soon as a new MAC address is learned or an existing
MAC address is deleted.
Examples
# Set the MAC Information queue length to 600.
<Sysname> system-view
