Unlike 3750 stacking, which uses special copper cables, 6500 VSS is done using 10 gig ports which can use the various 10 gig transceivers for those ports (copper or gig). I am curious to hear peoples take on stacking core switches or not? Obviously both have pros and cons. Thankfully I was in a maintenance window and. 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. Used for redundancy / failover. 5 Repeat the process for each SVI until all layer 3 interfaces have been moved over and the 9500 is the doing the routing , 6500 becomes a layer 2 VSS. Note: IF the new unit is not running same software version as existing stack, you need to match that. A VSS will allow two physical Cisco Catalyst Series Switches to operate as a single logical virtual switch called a virtual switching system. Stacking transforms standalone switches into single logical unit or group, with this group of switches showing the characteristics of a single switch. The default Switch priority is 1 and the highest is 15. Q. However, StackWise Virtual is NOT YET supported but this is part of the roadmap. you already have configuration backup done out of the box. * C9500-16X. 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”. If you reboot the whole Stack, then you have an outage of 10min. 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. No detailed configuration required to add stack member. For layer 2 services stack-wise works pretty well. So, I think I'd take some time to share with yourself what…In Cisco StackWise Virtual, the Cisco StackWise Virtual active switch runs the Layer 2 and Layer 3 protocols and features and manages the ports on both the switches. ago. Hello. I follow the below steps - high level. 9 release with single supervisor. However, Catalyst 9400 and Catalyst 9500 do not support Stack-Wise.
