I was doing some tests on our new C9600 cluster and I did the following: - Check the redundancy status and the second SUP never reach the "STANDBY HOT" status; Is it possible, when the stackwise is broken (only on box left) that the second SUP in the remaining switch get the status of "STANDBY HOT" in case of failure on the. This video introduces you to the Stackwise Virtual architecture and discusses how this architecture provides high availability in a network. Hi All, Currently scratching my head to figure out the maximum number of switches Stackwise Virtual can support. Stackwise virtual is almost the same as VSS. Options. 05-31-2018 03:31 PM. The virtual switch link (VSL) is a sp ecial link that carries control and data traffic between the two chassis of a VSS, as shown in Figure 4-4. standby) of the supervisor. Before answering, I find it interesting to detail a small difference between stacking functionality and other means of redundancy. 1. This PDF document provides the configuration guide for Cisco StackWise Virtual (SVL), a feature that allows two Catalyst 3850 switches to operate as a single logical entity. 1. So, no StackWise virtual/VSS there only stacking with a short cable. Select the image file, and click Open:Switch(config)# switch virtual domain domain_id . The Catalyst 9300 supoorts StackWise-480. . But 4500-x supports VSS and the 9500 supports StackWise Virtual which is the same as VSS. In response to Joe Ank. Cisco StackWise Virtual uses StackWise Virtual link to communicate system and protocol information between the peer switches and to carry data traffic between the two switches. switch 1 provision ws-c3850-48xs switch 2 provision ws-c3850-48xs stackwise-virtual domain 1 interface TenGigabitEthernet1/0/45 stackwise-virtual link 1 ! interface TenGigabitEthernet1/0/46. The StackWise solution is an enhancement of Cisco Virtual Switching System (VSS), available on Cisco Catalyst 6500 Series switches. Now Cisco 9K series switches comes with the Stackwise virtual in stead of VSS ( which is same concept technically). Pick run this IOS image via the local computer, and click Next >: (You can also run this image via the GNS3 VM) Select New Image, and click Browse to locate the image in your filesystem (you must supply your own!). LAN automate the two devices and any other Edge device that connects to them, Then convert the two devices to SVL manually. Modular Chassis. If you reboot the whole Stack, then you have an outage of 10min. Use show romvar CLI. If you do not save the changes, the changes will no longer be part of the startup configuration when the switch reloads. Here's my list of pros, cons, and questions I've come up with for Stackwise Virtual: Pros. When deploying Cisco StackWise Virtual, ensure that VLAN ID 4094 is not used. it broadcasts the domain ID out which can cause issues with duplicate domains - when you join 2 SVL with same domain ID, this has more difficulties to diagnosis the issue when you have Layer 2 issues. 12-29-2021 12:38 AM. Step 6: write memory. You must use either two VS-S720-10G-3C or two VS-S720-10G-3CXL supervisor engine modules. Cisco StackWise Virtual: Very similar to VSS, is like an evolution. Traffic on the StackWise Virtual link is load balanced with the same global hashing algorithms available for EtherChannels (the default algorithm is source. This article provides configuration. 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. This is expected behavior. Note: IF the new unit is not running same software version as existing stack, you need to match that. Here's my list of pros, cons, and questions I've come up with for Stackwise Virtual: Pros. 或QoS等三層特性。. Se interconectan a través de un portchannel configurado en los dos dispositivos que recibe el nombe de Virtual Switch Link (VSL). check all the hardware and supervisor the same as active. Fast Hello dual-active detection is supported only on supervisor module ports.

I am replacing these with Cat9ks that support StackWise Virtual. Unlike switch stacking, VSS uses standard Ethernet links to connect. The two switches operate as one; they share. Layer 2, Layer 3, Security, Quality of Service, Multicast, Application, Monitoring and Management, Multiprotocol Label Switching, High Availability, VXLAN BGP EVPN, and Cisco Sofware-Defined Access are supported. the stackwise virtual name is misleading read it as VSS ---> only two devices can be put together in a SVL pair. 06-04-2022 10:43 AM - edited 06-04-2022 10:44 AM. Introduction to Stacking vs VSS. The difference is that the feature known as MEC is found on the Catalyst 6500 VSS switches. Just deployed a pair of these (Catalyst 9500-40-X-A) for a small core at my work about 11 days ago. You cannot have a switch stack containing a mix of Catalyst 3850 and Catalyst 3650 switches. Step 5: end. This technology is very similar to VSS on the 6500 and 6700 series. Cisco StackWise Virtual is an inter-chassis system link between two switches that actively forwards traffic (Figure 1) in the StackWise Virtual domain. However, SVL connections will not initially be supported on the uplink module. Another thing to consider: VSS and Stackwise is a term used by appliances that run IOS. StackWise Virtual does not require the same "shared brain" implementation, making it more robust or resistant to defects that impact the entire redundant pair. Carl. 03-15-2019 03:46 AM.

You would need two VSS one per main site and one per. A Yes. Cisco StackWise Virtual uses SVL to communicate system and protocol information between the peer switches and to carry data traffic between the two switches. Bias-Free Language. You just configure the physical ports and add them to the domain on both switches. 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. You can check what the Domain Number is currently being. But 4500-x supports VSS and the 9500 supports StackWise Virtual which is the same as VSS. Se interconectan a través de un portchannel configurado en los dos dispositivos que recibe el nombe de Virtual Switch. This reduces the spanning tree domain and allows for Multi-chassis Etherchanneling (MEC). interface te1/0/2. Single control plane = single point of failure, most likely from config mistakes. The ICS in Chassis 2 remains unchanged. 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”. I've dealt with traditional Stackwise on 3750/X/3850 and VSS on 4500X, but haven't deployed Stackwise Virtual yet. As already noted by Leo, StackWise would be the "VSS" equivalent on a 9500, although, if I understand the datasheets, it's StackWise Virtual that would be most like VSS. 07-21-2021 03:05 PM.

The Cisco StackWise Virtual feature includes the following enhancements in this release: The feature is now supported on the following hardware: Cisco Catalyst 9400 Series Supervisor 1XL 25G Module (C9400-SUP- 1XL -Y) Cisco Catalyst 9400 Series 10 Slot Chassis (C9410R) Supervisor is NOT SUPPORTED (for now). Example: Device(config-if)#end: Returns to privileged EXEC mode. It is used during VSS boot up to identify a switch within a VSS domain. スタック機能：StackWise Virtual 物理的な2台のスイッチを仮想的に1台の論理スイッチとして運用可能にするネットワーククラスタ技術です。 2台のスイッチ間を接続するStackWise Virtual Link (SVL) は、イーサネットポートを使用します。What would be the potential Cisco StackWise Virtual throughput difference between using Hundred GigE, Forty Gigabit Ethernet or Twenty Five GigE interface for SVL links between switches? If the design and the supporting configs are deployed correctly, 2 10Gig ports for SVL use is more than enough. The Cisco Catalyst 4500 and 6500 also support something similar to Stackwise, it’s called VSS (Virtual Switching System) and I covered it in this lesson. 此功能允許使用10或40 Gbps端口堆疊相同型號的兩個交換機。. Stackwise Virtual (SWV) has taken over from VSS in Cisco's latest Catalyst multi-layer switches (the 9k Series).
