• vlan-mapping modulo stp bpdu-protection Use stp bpdu-protection to enable the BPDU guard function. Use undo stp bpdu-protection to disable the BPDU guard function. Syntax stp bpdu-protection undo stp bpdu-protection Default The BPDU guard function is disabled. Views System view Predefined user roles network-admin Examples # Enable the BPDU guard function. system-view [Sysname] stp bpdu-protection stp bridge-diameter Use stp bridge-diameter to specify the network diameter.
An appropriate setting of hello time, forward delay, and max age can speed up network convergence. The values of these timers are related to the network size, and you can set the timers by setting the network diameter. With the network diameter set to 7 (the default), the three timers are also set to their defaults. Each MST region is considered a device, and the configured network diameter of the switched network is effective only on MSTI 0 (or the common root bridge).
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 # Configure FortyGigE 1/0/1 to send only standard-format (802.1s) MSTP packets. system-view [Sysname] interface fortygige 1/0/1 [Sysname-FortyGigE1/0/1] stp compliance dot1s stp config-digest-snooping Use stp config-digest-snooping to enable digest snooping.

Syntax stp global config-digest-snooping undo stp global config-digest-snooping Default The feature is disabled globally. Views System view Predefined user roles network-admin Usage guidelines Enable this feature both globally and on ports connected to other vendors' devices. To minimize impact, enable the feature on all associated ports before you enable it globally. Examples # Enable digest snooping on FortyGigE 1/0/1 and then globally.
Predefined user roles network-admin Usage guidelines When you enable the spanning tree feature, the device operates in STP, RSTP, or MSTP mode, depending on the spanning tree mode setting. When the spanning tree feature is enabled, the device dynamically maintains the spanning tree status of VLANs based on received configuration BPDUs. When the spanning tree feature is disabled, the device stops maintaining the spanning tree status. Examples # Enable the spanning tree feature globally.
stp loop-protection Use stp loop-protection to enable the loop guard function on the ports. Use undo stp loop-protection to disable the loop guard function on the ports. Syntax stp loop-protection undo stp loop-protection Default The loop guard function is disabled. Views Layer 2 Ethernet interface view, Layer 2 aggregate interface view Predefined user roles network-admin Usage guidelines On a port, the loop guard function is mutually exclusive with the root guard function or the edge port setting.

Predefined user roles network-admin Parameters dot1d-1998: Configures the device to calculate the default path cost for ports based on IEEE 802.1d-1998. dot1t: Configures the device to calculate the default path cost for ports based on IEEE 802.1t. legacy: Configures the device to calculate the default path cost for ports based on a private standard. Usage guidelines If you change the standard that the device uses in calculating the default path costs, you restore the path costs to the default.
You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port that operates in full duplex mode. HP recommends that you use the default setting, which lets the device automatically detect the port link type. The stp point-to-point force-false or stp point-to-point force-true command configured on a port in MSTP mode is effective on all MSTIs or VLANs.
Usage guidelines The smaller the value, the higher the port priority. If all ports on your device use the same priority value, the port priority depends on the port index. The smaller the index, the higher the priority. 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.

Views System view Predefined user roles network-admin Parameters instance instance-list: Configures the device as a secondary root bridge in the MSTIs that are specified by an instance list, in the format of instance-list = { instance-id [ to instance-id ] }&<1-10>, where &<1-10> indicates that you can specify up to 10 instances or instance ranges.
Usage guidelines On a port, the loop guard function and the root guard function are mutually exclusive. 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.
stp tc-protection threshold Use stp tc-protection threshold to configure the maximum number of forwarding address entry flushes that the device can perform within a certain interval (every 10 seconds). Use undo stp tc-protection threshold to restore the default. Syntax stp tc-protection threshold number undo stp tc-protection threshold Default By default, the device can perform a maximum of six forwarding address entry flushes every 10 seconds.
Usage guidelines When TC-BPDU transmission restriction is enabled on a port, the port does not send TC-BPDUs to the other ports, and it does not delete the MAC address entries. 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.

Syntax stp timer max-age time undo stp timer max-age Default The max age is 2000 centiseconds. Views System view Predefined user roles network-admin Parameters time: Sets the max age in centiseconds in the range of 600 to 4000 in increments of 100 (as in 600, 700, 800).
undo stp timer-factor Default The timeout factor of a device is set to 3. Views System view Predefined user roles network-admin Parameters factor: Sets the timeout factor in the range of 1 to 20. Usage guidelines After the network topology is stabilized, each non-root-bridge device forwards configuration BPDUs to the surrounding devices at the interval of hello time to determine whether any link is faulty.
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.
