Stp Compliance - 3Com 8807 Command Reference Manual

MSTP Configuration Commands 181
Description
Use the stp bridge-diameter command to configure the switching network
diameter. Use the undo stp bridge-diameter command to restore the default
network diameter.
The definition of network diameter: Maximum count of switches between the
farthest communication ends.
The stp bridge-diameter command configures the switching network diameter
and determines the three time parameters of MSTP accordingly. This configuration
takes effect on CIST only but makes no sense for MSTI.
The spanning tree convergence can be speeded up, when Hello Time, Forward
Delay, and Max Age are well configured. These parameters are related to the
network scale.
You can configure the network scale to get the time parameters. When users
configure the bridge-diameter parameter of the switch, MSTP will automatically
set Hello Time, Forward Delay, and Max Age to moderate values. When
bridge-diameter defaults to 7, the time parameters also take their respective
default values.
Related command: stp timer forward-delay, stp timer hello, stp timer
max-age.
n
The stp bridge-diameter command configures the switching network diameter
and determines the three MSTP time parameters (Hello Time, Forward Delay, and
Max Age) accordingly.
Example
# Set the diameter of the switching network to 5.

stp compliance

Syntax
stp compliance { legacy | dot1s | auto }
View
Ethernet port view
Parameter
legacy: Indicates that the port sends and receives private MSTP packets.
dot1s: Indicates that the port sends and receives standard MSTP packets.
auto: Indicates the port has the auto-sensing function. The port can automatically
adjust the format of the packet to be sent based on the format of the received
packet.
