Management method of stacked switch provided by the present invention, mainly comprises the step as lower part:
(1) set up stacking
Set up stacking before, need guarantee that all switches are in off-mode, the electrical connection of the band of switch can cause stacking failure; Then connect contiguous switch by heap superimposing thread, with heap superimposing thread, the uplink port of a switch and the downlink port of another switch are coupled together, and guarantee that any two inter-exchanges only have a stacking wired link.The stacking of external or ring-like topological structure can be set up like this.This is stacking to get final product electrifying startup afterwards.(2) topology detection
In stacking each switch, all include and carry out topology detection device in its CPU, it can send topology detection bag to contiguous switch, thus obtains its corresponding information, finally can obtain whole stacking topological structure information.These topology detection devices compare topological structure information in received topology detection bag and self topological structure information.If the priority of self is high, then give up received detection bag.If the priority of self is low, then invested by the topology information of self in this topology detection bag, to neighbor switches transmission, and feedback message gives former switch.And by the learning ability that these switches have, the whole stacking topology information of final acquisition is stacking.
Whole stacking topology information comprises as lower part: stacking connected mode, as external or ring-like; The number of the switch connected; The details of each switch, comprising: the type (second layer or third layer) of switch, the port arrangement (12G, 240G or 48G) of switch, the power system capacity (cpu power, Installed System Memory size etc.) of switch, the software version etc. of switch.
(3) host exchange is elected
Logically, host exchange is whole stacking representative, user by the IP address of host exchange manage stacking in other switch.This host exchange can manually be arranged, or is automatically elected by an ordering mechanism.This ordering mechanism is the build-in attribute based on these switches, as the MAC Address (MediaAccessConttrolAdress) of switch and priority wherein.Generally be in the primary switch of ordered list and be considered to host exchange.In another embodiment of the invention, this ordering mechanism can be integrated and carry out in topology detection bag, so a switch can be selected to be host exchange at topology detection-phase.
After this host exchange is chosen, then remaining switch is as from switch.This host exchange can carry out interaction by a user interface and a remote network manager, receives the demand order of user; And can send demand 7 order message in stacking from switch; After carrying out corresponding operating after switch receives these demands/order message, by response message loopback to host exchange; And when from switch, event occurs, then it also can produce event information and send host exchange to.
When host exchange is when machine, then host exchange for subsequent use becomes new host exchange; If when there is no host exchange for subsequent use, then allow and the most forwardly in ordered list become host exchange from switch, and restart all switches, re-start topology and detect operation.
