Stp Transmit-Limit; Vlan-Mapping Modulo - H3C s3600 series Command Manual

stp transmit-limit

Syntax
stp transmit-limit packetnum
undo stp transmit-limit
View
Ethernet port view
Parameters
packetnum: Maximum number of configuration BPDUs a port can transmit in each hello time. This
argument ranges from 1 to 255.
Description
Use the stp transmit-limit command to set the maximum number of configuration BPDUs the current
port can transmit in each hello time.
Use the undo stp transmit-limit command to restore the maximum number to the default value.
By default, the maximum number of configuration BPDUs a port can transmit in each hello time is 10.
A larger number configured by the stp transmit-limit command allows more configuration BPDUs to be
transmitted in each hello time, which may occupy more switch resources. So you are recommended
configure it to a proper value to avoid network topology jitter and prevent MSTP from occupying too
many bandwidth resources.
Related commands: stp interface transmit-limit.
Examples
# Set the maximum number of configuration BPDUs that can be transmitted through Ethernet 1/0/1 in
each hello time to 15.

Parameters
modulo: Modulo by which VLANs are mapped to MSTIs, in the range of 1 to 16.
Description
