Use stp no-agreement-check to activate No Agreement Check on a port. I thought how to fix this problem, there is a command for stp in 3com Switches: “Stp no-agreement-check” I disabled it on each port then turned it on and activated and activated stp, now the PCs take leases faster at startup. By running the stp no-agreement-check command, a common rapid transition mechanism is configured on a port. . Ports 4/1 to 4/24 connect to UNIX workstations. .… Use the spanning-tree max-hops command to set up the number of hops in an MST region before the BDPU is eliminated and port information is out of date. Use the “no” form of this command to restore the default configuration. If a port`s priority is changed in an MSTI, MSTP recalculates the port`s role and initiates a state transfer in the MSTI. . . .

l MSTI port settings: port status, role, priority, road cost, designated bridge, designated port, remaining jump and if fast state transfer is activated (for designated ports). . . . Filtering and flooding modes are relevant when the clamp is disabled globally or on a single interface. . Shows the time of Squeeze-Tree-Hello in a matter of seconds. The range runs from 1 to 10. View information about ports that are blocked by STP protection features. .

. . Type show spantree vlan_id to check that Switch 15 is the trunk of all corresponding VALAs. In PVST mode, the diameter of the configured network is only used on the root bridges of the specified VLANs. The default setting is auto, and the cross-viewouse display automatically detects whether a port is connecting to a point-to-point connection. . . .

Hello Time is the interval in which inter-arborescent trees send configuration BPDUs to maintain the cross-sectional structure. If a device does not receive the configuration BPDS within the defined period, a new process for calculating the tightening structure is triggered. It is recommended to indicate the network diameter of the network using the main root root control and to have the optimal settings of these three timers automatically calculated. BPDU protection can be activated if the clamp is activated (useful when the port is in PortFast mode) or disabled. . Set the cost of the Ethernet port road 1/0/1 in MSTI 2 to 200. . force-false: Shows the type of non-point-to-point shortcut. Use the stp timer forward-delay command to set the delay timer to the AP.

The port ID displayed is insignificant for a port that does not support port priority. IDENTIFICATION of the MSTI, which includes an abnormally blocked port. Instance-ID: shows the status and statistical information of a specific MSTI. The minimum id instance value is 0, which represents the common internal tightening structure (ISTC), and the scope of the instance-id is 0 to 15. . stp port-log – all | | instance list vlan-id-list – Before setting up STP, select a switch as a strain of the cross-sectional structure. This switch should not be the most powerful switch, but choose the most central switch in the network. The whole data flow on the network is from the point of view of this switch. Also select the least disturbed switch in the network. Backbone switches often serve as a cross tree root, as these switches usually do not connect to the terminals. Even changes and changes within the network are less likely to influence these switches. .

. . The device activates the activation ports after a port status detection interval. . . . By default, the maximum throughput of all AP 10 ports, i.e. each port can send up to 10 BPDUs in any time frame. In order for the aircraft`s intended upstream port to be able to quickly transmit its condition, do not activate an agreement check on the downstream connection of the aircraft. .

Bridge Time: Hello 2s MaxAge 20s FwdDelay 15s MaxHops 20 External Road Charges. The bridge can automatically calculate the default route cost of a port or, moreover, you can use the stp cost command to set up a port`s path cost.
