Introduction to Stacking vs VSS Stacking transforms standalone switches into single logical unit or group, with this group of switches showing the. The two technologies are aimed to have feature parity. This is similar to the Virtual switching system (VSS) in the traditional 4500,6500 series. 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. Igual que Stack el objetivo de VSS es tener logicamente un solo dispositivo Virtual, una sola administración para los dos Switches. Here's my list of pros, cons, and questions I've come up with for Stackwise Virtual: Pros. While Cisco catalyst services switches support VSS (Cisco 4500, 6500, 6800 catalyst Switches) Juniper EX and QFX (EX2200, EX3300, EX4200, EX4500 and EX4550, EX4600, EX8200, QFX Series) support VC technology. We are planning to connect our two data centers separated by two kilometers using two Catalyst 9500s but this would be wonderful if we can use two Catalyst 9300 switches. ago. At least in my opinion. 1. Virtual Port Channel - A Virtual Port Channel (vPC) is an enhancement to MEC that allows for the same sort of functionality — building a port channel across two switches — without the need for Stackwise or VSS. Now, a single switch is not going to support all three of these. If talking in Cisco terms, the main difference between vPC and basic stacking (StackWise, FlexStack) is excluding of splitbrain situation, when both members become a master and continue to forwarding. example: VSS: chassis-1 primary sup. Cisco Catalyst 9500-48Y4C does not support StackWise virtual at the moment. 3rd: configure dual active detection link to ensure both switches are active simultaneos: conf t interface TenGigabitEthernet1/0/15.

This is an important function of VSS because it prevents both supervisors from becoming active in event of a VSL link failure. VSS, Stackwise, Stackwise Virtual are the same. Please correct me if this is true. Can anyone tell me if the Cisco 9410 supports Stackwise virtual? We are looking at replacing our 6509 running VSS so we need this feature, from what I have read only the smaller chassis are supported. There is no direct distance limitation in SWV, and the condition is that the two switches that make up SWV are directly connected. Step 6: write memory. Stackwise Virtual = uses data interfaces to form a logical stack. A: The Catalyst 9200 supports StackWise®-160 while the Catalyst 9200L supports StackWise-80. The in-chassis standby Supervisors if available will be powered-off by the system during the StackWise Virtual conversion. In order to bond these two using VSS, we will have to do the following: Configure a virtual switch domain on both switches and configure one switch as “switch 1” and the other one as “switch 2”. Better link utilization, loop-free topology for L2 connectivity. A: The Catalyst 9200 supports StackWise®-160 while the Catalyst 9200L supports StackWise-80. 03-15-2019 03:46 AM. stackwise-virtual Example: Step9 Device(config)#stackwise-virtual Enablespagpdual-activedetection. domain id Example: Device(config-stackwise-virtual)#domain 2 Step4 end ReturnstoprivilegedEXECmode. no stackwise-virtual dual-active-detection.
