Image Version = Cisco IOS Software, Catalyst 元 Switch Uptime in current state = 6 days, 2 hours, 41 minutes You can verify this setup with the following commands:Īvailable system uptime = 6 days, 2 hours, 41 minutes The SV standby switch is also considered a hot-standby switch, since it is ready to become the active switch and take over all functions if something happens to the active switch. The peer chassis is referred to as the SV standby switch. The switch acting as the single management point is referred to as the SV active switch. A single switch in the StackWise Virtual domain is elected as the central management point for the entire system when accessed via management IP or console.ġ See the “Hardware and Software Requirements” section of this document for details on all StackWise Virtual hardware and software requirements. This includes Layer 3 protocols such as Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Border Gateway Protocol (BGP), as well as Layer 2 protocols such as Spanning Tree Protocol (STP), Unidirectional Link Detection Protocol (UDLD), Flow Control, and LACP. The fundamental design of a StackWise Virtual domain allows the centralized management of all network and device resources. If the destination is on the other switch in the StackWise Virtual domain, ingress processing is performed on the ingress switch and then traffic is forwarded over the StackWise Virtual link to the egress switch where only egress processing is performed. 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.
