system-view [Sysname] stp tc-protection disable Related commands stp tc-protection threshold stp tc-protection threshold Use stp tc-protection threshold to configure the maximum number of forwarding address entry flushes that the device can perform every a certain period of time (10 seconds). Use undo stp tc-protection threshold to restore the default.
Views System view Default command level 2: System level Parameters time: Sets the forward delay (in 0.01 seconds), in the range of 400 to 3000 in increments of 100 (as indicated by 400, 500, 600). Usage guidelines The forward delay timer determines the time interval of state transition. To prevent temporary loops, a spanning tree port goes through the learning (intermediate) state before it transits from the discarding to the forwarding state.
Parameters time: Sets the hello time (in 0.01 seconds), in the range of 100 to 1000 in increments of 100 (as indicated by 100, 200, 300). Usage guidelines Hello time is the time interval at which spanning tree devices send configuration BPDUs to maintain spanning tree. If a device fails to receive configuration BPDUs within the set period of time, a new spanning tree calculation process will be triggered due to timeout. HP recommends not setting the hello time with this command.
HP recommends not setting the max age timer with this command. Instead, you can specify the network diameter of the switched network by using the stp bridge-diameter command and let spanning tree protocols automatically calculate optimal settings of the max age timer. If the network diameter uses the default value, the max age timer also uses the default value. Examples # In MSTP mode, set the max age timer to 10 seconds.
[Sysname] stp timer-factor 7 Related commands stp timer hello stp transmit-limit Use stp transmit-limit to set the maximum number of BPDUs that the ports can send within each hello time.
