[Sysname] stp timer-factor 7
Related commands
stp timer hello
stp transmit-limit
Use stp transmit-limit to set the maximum number of BPDUs that the ports can send within each hello
time.
Use undo stp transmit-limit to restore the default.
Syntax
stp transmit-limit limit
undo stp transmit-limit
Default
The maximum transmission rate of all ports is 10. Each port can send up to 10 BPDUs within each hello
time.
Views
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default command level
2: System level
Parameters
limit: Sets the maximum number of BPDUs the ports can send within each hello time. The value range is
1 to 255.
Usage guidelines
Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all member ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port leaves
the aggregation group.
A larger maximum transmission rate value requires more system resources. An appropriate maximum
transmission rate setting can prevent spanning tree protocols from using excessive bandwidth resources
during network topology changes. HP recommends you to use the default value.
Examples
# Set the maximum transmission rate of port GigabitEthernet 4/0/1 to 5.

[Sysname] interface GigabitEthernet 4/0/1

vlan-mapping modulo
Use vlan-mapping modulo to map VLANs in the MST region to MSTIs according to the specified modulo
value, quickly creating a VLAN-to-instance mapping table.
