Summary 183
Rstp introduction 184
Mstp introduction 186
A cist priority vector calculation 187
Assumptions 187
Bridge b from the pd port of bridge d is as follow the total root is rd the 187
Cost is ercb the domain root is rrb the inner root path cost is ircb the 187
Designated bridge id is b the designated port is b the designated port id 187
In cist priority vector is composed of the total root outer root path cost domain 187
In order to facilitate the subsequent description we make the following 187
In the initial condition the information carried in the message sent out by the 187
Is pb the id of port receiving bpdu message is pb 187
Msti priority vector calculation method as follow 187
Pb port of the bridge b is as follow the total root is rb the outer root path 187
Port receiving bpdu message 187
Priority vector calculation 187
Priority vector of the spanning tree we will introduce the cist priority vector and 187
Root inner root path cost designated bridge id designated port id and the id of 187
The information carried in the message which is received by pb port of 187
The message the most important information carried in the message is the 187
The mstp role of all bridges is computed according to the carrying information in 187
A switch a role selection process 190
And the switchb is better than switchc the link path costs are 4 5 and 10 190
Another domain alone 190
Figure 8 1 supposing that the bridge priority of switcha is better than switch b 190
In initial state the port of every device will be calculated to be the designated port and 190
Role selection process 190
State of the figure 8 1 is shown in the table 8 2 190
Switcha and switchb belong to the same domain and switchc belongs to 190
The cist instance calculation process will be introduced briefly as follow with the 190
The message priority vector carried in the message sent out by the device in initial 190
The port priority vector of all ports of device keep the same as the message priority 190
Vector in initial state 190
Will send out the message priority vector which makes it to be the root bridge 190
According to different destination please execute corresponding steps refer to the 193
As long as the same configuration the two switches belong to the same domain 193
Background information 193
Before configuring switch to join designated mst domain it needs to configure 193
Configure device to join designated mst domain 193
Following table 193
Mst domain name 193
Mst domain revision level 193

Default to configure 196
Attached list 197
Anyone forges configuration message and attacks switch maliciously when the 198
Background information 198
Bpdu protection 198
Circumstances the edge interface will not receive bpdu message of stp but if 198
Configure mstp protection function 198
Configured the as edge interface to realize interface fast switching under normal 198
Edge interface receives the configuration message system will configure these 198
For the access layer device the access interface usually connects with user 198
Interfaces to be non edge interface automatically and will calculate stp again 198
Prevent this network attack 198
Terminal such as pc or file server at this time the access interface can be 198
This will results in network topology concussion bpdu protection function can 198
According to different destination please execute corresponding steps refer to the 200
After enabling tc bpdu message attack function the number of times which 200
Deletion operation will cause great burden to the device and bring great hidden 200
Following table 200
It can avoid frequent deletion of mac table item and arp table item so as to 200
Mstp processes bpdu message of tc type can be configured per unit time if 200
Process 200
Protect the switch 200
Purpose 200
Specified by threshold for other bpdu messages of tc type beyond the 200
The configured threshold the mstp process only deals with the designated times 200
The number of bpdu messages of tc type received by mstp process exceeds 200
Threshold after the timer expires mstp process only deals with once in this way 200
Trouble to the network stability 200
When need to configure mstp protection user can use this section operation 200
According to different destination please execute corresponding steps refer to the 201

Poe function configuration 224
Summary 224
According to the different purposes execute corresponding step please refer to the 225
Auto mode it is recommended that user uses the force standard or force high mode 225
Background information 225
Configure power supply mode 225
Following table 225
Function 225
Generally it is recommended that user uses the default mode of half auto 225
If using one of the two modes user must enable the enhanced detection power supply 225
Progress 225
Qsw 2800 pe pe supports four power supply modes they are auto force 225
Standard force high and half auto 225
When the device cannot supply electricity normally using non standard pd in half 225
According to the interface number the interface number is greater the priority is 226
Background information 226
Configure poe power supply parameter 226
Configure the pd device description connected with the interface on the device it is 226
Convenient for user to manage the downstream pd device 226
Critical equipment can be first powered when the power consumption of pd equipment 226
Currently qsw 2800 pe pe only supports power supply in signal line mode timing 226
Electricity for it 226
Higher and the port with greater interface number will be powered first 226
Insufficient if the priority of different ports is the same it will order the priority 226
Is greater than the total power supplied by the pse when the pse power is 226
Poe power supply port supports three priorities the port priority ensures that the 226
Power supply and power supply alarm function 226
Progress 226
Pse can only detect the standard pd and supply electricity for it after enabling pse 226
The command of configuring the threshold power of pse in the global configuration 226
The pd device according with the 802 af protocol is the standard pd device usually 226
To detect the non standard pd pse can detect the non standard pd and supply 226
View is used to protect the switch to avoid the influence of the unstable power supply 226
