Each MST region is considered as a device, and the configured network diameter of the switched network is only effective for the CIST (or the common root bridge), not for MSTIs. Related commands: stp timer forward-delay, stp timer hello, and stp timer max-age. Examples # In MSTP mode, set the network diameter of the switched network to 5. system-view [Sysname] stp bridge-diameter 5 stp compliance Syntax stp compliance { auto | dot1s | legacy } View undo stp compliance Ethernet interface view, Layer 2 aggregate interface view Default level 2: System level Parameters auto: Configures the ports to recognize the MSTP BPDU format automatically and determine the format of MSTP BPDUs to send. dot1s: Configures the ports to receive and send only standard-format (802.1s-compliant) MSTP BPDUs. legacy: Configures the ports to receive and send only compatible-format MSTP BPDUs. Description Use stp compliance to configure the mode the specified ports will use to recognize and send MSTP BPDUs. Use undo stp compliance to restore the default. By default, a port automatically recognizes the formats of received MSTP packets and determines the formats of MSTP packets to be sent based on the recognized formats. Configured in Ethernet interface view, the setting takes effect on that interface only. 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. Examples # Configure GigabitEthernet 1/0/1 to receive and send only standard-format (802.1s) MSTP packets. system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] stp compliance dot1s 107

View
Ethernet interface view, Layer 2 aggregate interface view
Default level
2: System level
Parameters
auto
: Configures the ports to recognize the MSTP BPDU format automatically and determine the format
of MSTP BPDUs to send.
dot1s
: Configures the ports to receive and send only standard-format (802.1s-compliant) MSTP BPDUs.
legacy
: Configures the ports to receive and send only compatible-format MSTP BPDUs.
Description
Use
stp compliance
to configure the mode the specified ports will use to recognize and send MSTP
BPDUs.
Use
undo stp compliance
to restore the default.
By default, a port automatically recognizes the formats of received MSTP packets and determines the
formats of MSTP packets to be sent based on the recognized formats.
Configured in Ethernet interface view, the setting takes effect on that interface only.
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.
Examples
# Configure GigabitEthernet 1/0/1 to receive and send only standard-format (802.1s) MSTP packets.
