Stp Compliance - 3Com S7906E Command Reference Manual

Use the undo stp bridge-diameter command to restore the default.
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. You can set these three timers indirectly by
setting the network diameter. Based on the network diameter you configured, MSTP automatically sets
an optimal hello time, forward delay, and max age for the device. With the network diameter set to 7 (the
default), the three timer are also set to their defaults.
Note that this configuration is effective for the CIST and root bridge only, and not for MSTIs.
Related commands: stp timer forward-delay, stp timer hello, stp timer max-age.

stp compliance

Syntax
stp compliance { auto | dot1s | legacy }
undo stp compliance
View
Ethernet port view, port group view, Layer-2 aggregate port view
Default Level
2: System level
Parameters
auto: Configures the port(s) to recognize the MSTP BPDU format automatically and accordingly
determine the format of MSTP BPDUs to send.
dot1s: Configures the port(s) to receive and send only standard-format (802.1s-compliant) MSTP
BPDUs.
legacy: Configures the port(s) to receive and send only compatible-format MSTP BPDUs.
Description
Use the stp compliance command to configure the mode the port(s) will use to recognize and send
MSTP BPDUs.
Use the undo stp compliance command to restore the system default.
The default mode is auto, namely all ports recognize the BPDU format automatically.
Note that:
Configured in port view, the setting takes effect on the current port only; configured in port group
view, the setting takes effect on all ports in the port group.
Configured in Layer-2 aggregate port view, the setting takes effect only on the aggregate port.
Configured on the member port in an aggregation group, the setting can take effect only after the
1-16
