Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
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
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 that you use the default value.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on 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 maximum transmission rate of port Ten-GigabitEthernet 1/0/1 to 5.

[Sysname] interface ten-gigabitethernet 1/0/1

vlan-mapping modulo
Use vlan-mapping modulo to map VLANs in the MST region to MSTIs according to the specified modulo
value and quickly create a VLAN-to-instance mapping table.
Syntax
vlan-mapping modulo modulo
Default
All VLANs are mapped to the CIST (MSTI 0).

Parameters
modulo: Sets the modulo value in the range of 1 to 64.
Usage guidelines
You cannot map a VLAN to different MSTIs. If you map a VLAN that has been mapped to an MSTI to a
new MSTI, the old mapping is automatically removed.
