Stp Compliance - HP A5830 Series Command Reference Manual

By default, the network diameter of the switched network is 7.
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 will also be set to their
defaults.
To set the network diameter of an STP/RSTP/MSTP switched network, use this command without
specifying any VLAN. To set the network diameter of a specified VLAN or multiple VLANs in a PVST
switched network, use this command with a VLAN list specified.
In STP, RSTP, or MSTP mode, 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.
In PVST mode, the network diameter configuration takes effect only on the root bridge.
Related commands: stp timer forward-delay, stp timer hello, and stp timer max-age.
Syntax
stp [ vlan vlan-list ] bridge-diameter diameter
undo stp [ vlan vlan-list ] bridge-diameter
View

Default level
2: System level
Parameters
vlan vlan-list: Specifies a VLAN list in the format of vlan-list = { vlan-id [ to vlan-id ] }&<1- 1 0>, where the
vlan-id parameter represents the VLAN ID, in the range of 1 to 4094, and &<1- 1 0> indicates that you can
specify up to 10 VLAN IDs or VLAN ID ranges.
diameter: Specifies the switched network diameter, in the range of 2 to 7.
Examples
# In MSTP mode, set the network diameter of the switched network to 5.
<Sysname> system-view
[Sysname] stp bridge-diameter 5
# In PVST mode, set the network diameter of VLAN 2 to 5.
<Sysname> system-view
[Sysname] stp mode pvst
[Sysname] stp vlan 2 bridge-diameter 5
