The next step is to enable the StackWise Virtual feature and configure its settings. The VSS requires 67xx series switching modules. 9400 will, in the roadmap, will support Stackwise Virtual. The switch should report a good connection when you enter the show switch detail user EXEC command. Trunking is different from switch stacking. The SVL connections do not run any network protocol and remain transparent in Layer 2 and Layer 3 network topologies. The 2 things do not really compare. I had a VSS build that had duplicate domains and caused some issues with the duplicate site (packet loss primarily), once I changed the domain ID all was good but was a nightmare to troubleshoot. It probably has plenty of bandwidth to serve as a core for a small server hosting environment + end users. what happens to the former active switch. 1. What does it mean? HSRP and VRRP operate in active-active mode from data plane standpoint, as opposed. If there is mismatch between Switch-1 and Switch-2. ISSU is supported in dual SUP HA and StackWise Virtual system. 9400/9500/9600 do stack wise virtual, note that you can only have two switches in the stack (annoyingly) VS a stack using stackwise cables (9300) you can have 8 or 10 from memory. VSS, Stackwise, and Stackwise-virtual make multiple switches look like one managed device. Stacking is supported on different models; like the 3850s, 3650, 9300, etc. There are two Virtual Stackwise Links of 10G as part of the SVL domain 1. Rather than a configurable protocol, stacking is done by linking switches together to form a “virtual switch”. Cisco ® Catalyst ® 9000 platform StackWise ® Virtual technology allows the clustering of two physical switches together into a single logical entity. The options to update the old switch were. Stackwise Virtual = uses data interfaces to form a logical stack. 或QoS等三層特性。.
