are border upon cannot connect together physically. Therefore, one stracking will divide

into two stracking. This process is called split.

(6) Priority of member

Priority of member is the member facilities attribute, mainly use for the role selection

for confirming the role of each members. If the facility has higher the priority, it will have

higher chance to become the Master. The default setting of the facilities is 1. If the user

want to pre-set particular facility become the Master, he can increase the priority value of

that facility manually before build up the VSF.

10.1.1.3 Glossary

VSF is the short form of the Virtual Switching Framework.

VSF Port: VSF port, is a mode on port-channel

VSF AM: the master card of the VSF activities

VSF SM: the backup master card of the VSF activities

VSF Slave: the slave card of VSF, to operate the VSF agreement ,during the

switching it means Chassis AM，the not selecte one is VSF AM or VSF SM

VSF Member: the member facilities of VSF

VSF Master Member: the master member facility of VSF

VSF Standby Master Member: the standby master member facility of VSF

VSF Slave Member: the slave member facilities of VSF

HA: High Availability

AM: Active Master, activities controller. It is the switch whose working mode is Master

is and it is in the operation status, each of the cassette vsf group can only has a AM at

each time.

SM：Standby Master, the working mode in the cassette vsf group is Master and it

locates in the standby status.

SSO: Stateful Switchove, the data of in-phase agreement layer will occour the

switchover, the backup master agreement apply function which can connect to

corresponding function fleetly. The data of this function will not be lose, but the router

agreement data is not in-phase

NSF: None Stop Forwarding. Using the independent management characteristics of

data layer control, data layer can still transmit data normally as the control layer is out of

order

NSF/SSO: Nonstop Forwarding with Stateful Switchover means that undergo the

SSO “master-backup interchange”, the data transmit is not affected

Syn process：HA synchronization processes responsable for activities control and
