Specifying The Maximum Transmission Rate Of Stp Packets On A Port; Set Specified Port To Be An Edgeport - 3Com Switch 4500 26-Port Configuration Manual

Specifying the
Maximum Transmission
Rate of STP Packets on a
Port
Set Specified Port to be
an EdgePort
You can use the following command to set the multiple value of hello time of a
specified bridge.
Perform the following configurations in System View.
Table 179 Set Timeout Factor of the Bridge
Operation
Set the multiple value of hello time of a specified bridge
Restore the default multiple value of hello time
It is recommended to set 5, 6 or 7 as the value of multiple in the steady network.
By default, the multiple value of hello time of the bridge is 3.
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.
Table 180 Specifying the Maximum Transmission Rate of STP Packets on a Port
Operation
Specify the maximum transmission rate of STP
packets on a port
Restore the default 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.
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.
Table 181 Set Specified Port as the EdgePort
Operation
Set a specified port as an EdgePort or a non-EdgePort
Set the specified port as the non-EdgePort, as defaulted
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
