2. VSF can optimize the uninterruptedly communication

Switches status conk out switching will not interrupt the applications which are using

the internet status information. With the help of VSF, if one of the virtual switch

members is out of order, no need to continous the reconstringency of L2/L3 can restart

the virtual switch recover in short time. The active mode must be used for port group.

3. VSF can expand the system bandwidth capacity

In the vsf switch can activate all the L2 bandwidth, can carry on the equilibrium of

load on the multiple members of VSF when expanding the bandwidth.

10.1.1.2 Basic Concept

(1) Role

Each of the facilities in the VSF is called member facility. According to the function of

each member facility, will divide into 2 different roles:

Master: Responds for manage entire VSF

Standby Master: Is the standby member of VSF, as the Master backup facility for

operation. When the Master is out of order, the systems will handover to Standby Master

automatically to perform the original job of Master.

Slave: The member facilities that are other than Master and Standby Master in VSF.

Master, Standby Master and Slave are produced by election. For entire VSF, it can

only have one Master, one Standby Master, other members should be Slave.

(2) VSF port

It is a logic port which is particular use for VSF. It divides into vsf-port1 and vsf-port2,

need to colligate with the VSF physical port and then become efficitive.

(3) VSF physical port

It is the facility that is used for physical connection port for VSF. VSF physical port can

be VSF specific port, Ethernet port or light port (different equipment and the model will

using different port, please equipt it according to the virtual situtation). Usually, Ethernet

port and light port respond for transmitting operation message. After they colligate with the

VSF port, they will become the VSF physical port. They will use for transmitting the

message within the members. The message including VSF related negotiation message

and the operation message that needs to cross over different members.

(4) Merge

Two different VSF operation separately, throughout the physical connection and

configuration, it will become one VSF. This process is called merge.

(5) Split

One VSF is formed. Due to the VSF link is out of order, it will cause the facilities that
