disabled, upon receiving TC/TCN packets, the port broadcasts TC packets to delete the
MAC address entries of the port in the STP active state on the bridge.
Perform the following configuration in system view.
Table 38-29

Command
Enable/disable ARP address update
stp update-arp
{
enable
|
disable
}
By default, ARP address update is enabled.
Note:
In general, the
STP update-arp disable
command works together with the
stp
reset-arp enable
command in the port view. That is, the system removes MAC and
ARP entries of the port after receiving TC/TCN packets.
38.2.20 Enabling/Disabling MSTP on a Port
You can use the following command to enable/disable MSTP on a port. You may
disable MSTP on some Ethernet ports of a switch to spare them from spanning tree
calculation. This is a measure to flexibly control MSTP operation and save the CPU
resources of the switch.
MSTP can be enabled/disabled on a port through the following ways.
I. Configuration in system view
