Each of the following boxes represents a possible. Single control plane = single point of failure, most likely from config mistakes. 09-15-2017 03:20 AM - edited 03-08-2019 12:02 PM. Assigns the router MAC address from a reserved pool of domain-based addresses. After the “stackwise-virtual link” command is executed on the range of ports, the switch will automatically bundle the links to form a port channel. ISSU is supported in dual SUP HA and StackWise Virtual system. However, VSS can offer more ports per virtual switch, as each VSS member can have up to 576 ports. I've dealt with traditional Stackwise on 3750/X/3850 and VSS on 4500X, but haven't deployed Stackwise Virtual yet. There are some software requirements for Stackwise-Virtual depending on the hardware platform you’re going to be running. Control data and power cables are used. As for as connecting the Cisco to Dell and other vendors, you can use LACP for bundling multiple uplinks in one logical connection. StackWise Virtual link is the link that connects the switches over Ethernet. Introduction Cisco® Catalyst® 9000 platform StackWise® Virtual technology allows the clustering of two physical switches together into a single logical entity. Enhanced PAgP dual-active detection is supported on supervisor module. Virtual Port Channel vs. Stackwise, particularly 9300, is "officially" 8 but can stack up to 16.
