HP Virtual Switching Framework (VSF) technology virtualizes multiple physical devices into one virtual fabric which provides high availability due to a significant reduction in recovery time simplified network design and management. Stacking technology has been around for almost a decade now. But, what makes VSF special is the fact that we don’t need dedicated stack cables to build the stack!
With VSF a stack can be built using just the regular Cat-6 Ethernet cables and Ethernet front ports on the switch.

VSF Deployment methods
- Auto-join/plug-and-play: configure one switch with VSF and a second, factory default switch that is connected will join and form a VSF automatically.
- Manual configuration: Configure both VSF members manually.
- VSF Strict provisioning: Configure one switch with VSF, and manually provision a second switch with Chassis type and mac-address; called strict provisioning.
A management plane, which provides administrators and management solutions access to management interfaces such as the CLI.
A control plane, which runs protocols and builds routing and MAC forwarding tables.
A forwarding plane, which processes and forwards packets.
- Runs network control and management protocols (STP, LACP, RIP, OSPF, Telnet, SNMP)
- Syncs protocol states to the “Standby” for hitless failover
- Manages the ASIC (forwarding) tables of *all* switches in the stack
- Provides commander-level HA
- Receives configuration and protocol state information from the commander
- Runs protocols in a passive mode where their runtime states are updated based on sync from the commander
- Is ready to take over as Commander of the Stack should the Commander fail
- Remaining switches (if any) are “Member” switches
- Only have a copy of the configuration but no knowledge of protocol state
- Will be upgraded to Standby if commander/standby fails
- Management simplicity: You no longer need to laboriously connect to, configure, and manage switches individually.
- Single logical redundant entity
- Eliminates the need for L2 redundancy protocols such as spanning tree (STP)
- Eliminates the need for L3 redundancy protocols such as Virtual Routing Redundancy Protocol (VRRP)
