R211x-HP Flexfabric 11900 Layer 2 - LAN Switching Command Reference

stp transmit-limit
Use stp transmit-limit to set the BPDU transmission rate of a port.
Use undo stp transmit-limit to restore the default.
Syntax
stp transmit-limit limit
undo stp transmit-limit
Default
The BPDU transmission rate of all ports is 10. Each port can send 10 BPDUs within each hello time.
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
mdc-admin
Parameters
limit: Sets the BPDU transmission rate in the range of 1 to 255.
Usage guidelines
The maximum number of BPDUs a port can send within each hello time equals the BPDU transmission
rate plus the hello timer value.
A larger BPDU transmission rate value requires more system resources. An appropriate BPDU
transmission rate setting can prevent spanning tree protocols from using excessive bandwidth resources
during network topology changes. HP recommends that you use the default value.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect on only that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect on only the aggregate
interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.
Examples
# Set the BPDU transmission rate of port Ten-GigabitEthernet 1/0/1 to 5.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] stp transmit-limit 5
vlan-mapping modulo
Use vlan-mapping modulo to map VLANs in an MST region to MSTIs according to the specified modulo
value and quickly create a VLAN-to-instance mapping table.
Syntax
