![]() The active and standby switches support local forwarding that will individually perform the desired lookups and forward the traffic on local links to uplink neighbors. Layer 3 protocols (routing protocols, etc.)įrom the data-plane and traffic-forwarding perspectives, both switches in a StackWise Virtual domain actively forward traffic.Layer 2 protocols (Bridge Protocol Data Units, Protocol Data Units, Link Aggregation Control Protocol, etc.).Management (Simple Network Management Protocol, Telnet, Secure Shell Protocol, etc.).All control plane functions are centrally managed by the SV active switch, including: Within a StackWise Virtual domain, one device is designated as the SV active switch, and the other is designated as the SV standby switch (Figure 3). To neighboring devices, a StackWise Virtual domain appears as a single logical switch or router. It uses Cisco IOS ® Stateful Switchover (SSO) technology, as well as Non-Stop Forwarding (NSF) extensions to routing protocols, to provide seamless traffic failover when one of the device fails over. ![]() StackWise Virtual (SV) combines two switches into a single logical network entity from the network control plane and management perspectives. The StackWise Virtual domain is supported with specific hardware and software components, which are described later in this white paper ![]() ![]() After the reload, both devices come back online as StackWise Virtual Pair. The conversion is a one-time process that requires a few simple configuration steps and a system reload.
