RSTP Configuration 251
By default, the multiple value of hello time of the bridge is 3.
Specifying the
Maximum Transmission
Rate of STP Packets on a
Port
The maximum transmission rate of STP packets on an Ethernet port is dependent
on the physical status of the port and the network architecture. You can specify it
as needed.
You can specify the maximum transmission rate on a port by using the following
commands.
Perform the following configuration in Ethernet Interface View.
Tab le 275 Specifying the Maximum Transmission Rate of STP Packets on a Port
Notably, though a higher transmission rate is introduced at larger Packetnum,
more Switch resources are consequently occupied. It is therefore recommended to
use the default value.
By default, an Ethernet port can transmit at most 3 STP packets within one Hello
Time.
Set Specified Port to be
an EdgePort
EdgePort is not connected to any Switch directly or indirectly via the connected
network.
You can use the following command to set a specified port as an EdgePort.
Perform the following configurations in Ethernet Port View.
Tab le 276 Set Specified Port as the EdgePort
In the process of recalculating the spanning tree, the EdgePort can transfer to the
forwarding state directly and reduce unnecessary transition time. If the current
Ethernet port is not connected with any Ethernet port of other bridges, this port
should be set as an EdgePort. If a specified port connected to a port of any other
bridge is configured as an edge port, RSTP will automatically detect and
reconfigure it as a non-EdgePort.
After the network topology changed, if a configured non-EdgePort changes to an
EdgePort and is not connected to any other port, it is recommended to configure
it as an EdgePort manually because RSTP cannot configure a non-EdgePort as an
EdgePort automatically.
Configure the port directly connected to the terminal as an EdgePort, so that the
port can transfer immediately to the forwarding state.
