Stackwise Virtual

StackWise Virtual (SVL) enables two physical Catalyst switches to operate as a single logical switch by combining their control planes over dedicated StackWise Virtual Links (SVL). This provides simplified management, unified forwarding, and sub-second failover without the complexity of traditional high-availability protocols.
