connected ports. Each switch can have two VSF links. The switches behave as a single virtual switch. 2930F
supports a maximum of four 10G ports.

NOTE: The preceding figure applies to a VSF stack having more than four members too.

Benefits of VSF

Simplified topology and easy management
A VSF fabric appears and behaves as one logical switch and is accessible by the network through a single IP
address.
1:1 redundancy
One member acts as the commander to manage and control the entire VSF fabric. One of the switches acts
as a standby and backs up the commander, and takes over in case of commander failure.
VSF port aggregation
A VSF link can aggregate upto eight VSF ports with the immediate neighboring member. This provides
redundancy till failure of seven VSF ports.
Distributed trunking
The Ethernet link aggregation feature can be used to aggregate physical links between the VSF and its
upstream or downstream devices across the VSF members. This eliminates the need for spanning tree and
also provides load balancing across all ports of the link aggregate.
Network scalability
The processing power is equal to the Commander, the forwarding capacity is equal to all the stack members
combined.

Up to 8 physical Ethernet
connections all 1G or 10G
NOTE: Spanning tree features are not necessary among VSF members.
Switch 2 - Standby
Switch 3 - Member
