First of all there is a big difference between VSS and VPC where Nexus vPC is introduced with Nexus 2,5 and 7K. The vPC is actually eliminate the need of STP on the member vPC ports and allow for efficient load sharing capabilities .The VSS on the other hand is a feature introduced with Cisco 6500 catalyst, its basically combines the Back plane throughput of ...

Stack Wise is not possible without the use of stack ports and stack cables and the maximum stack cable length i deal with was CAB-SPWR-150CM which was 1.5 m . so you can't stack over this distance . and also you can make use of this discussion enter link description here

VSS only allows you to aggregate two physical chassis at a time. Remember there are really only two main drivers to even using VSS (and many arguments against it depending on who you ask): Etherchannel aggregation across multiple physical devices for hardware redundancy. Ease of management/configuration by consolidating the two chassis into a single point ...

In fact I found out it is possible with IOS XE > 03.05.00 SG. This was not possible before, on IOS XE train 03.04.xx SG I have tried myself with IOS XE 03.05.02 SG and did not encounter any issues with a 4503-E on one side and a 4507+RE on the other side, the two of them having Sup7-LE. There is reference on this here

The two chassis must have the same number of slots. Refer to: Cisco: Configuring VSS - Chassis and Modules

This answer probably won't very useful today, but it's possible to stack 2960X via fiber. You need C2960X-FIBER-STK.

(m)LACP and vPC are Layer 2 technologies, thus they don't apply to layer 3 interfaces At layer 3 you use for example VRRP (to provide gateway to hosts) or routing protocols (like OSPF) to achieve redundancy and automatic switchover.

If you configured each pair of 4500s as a VSS, then linked them together with an active/LACP port channel you could achieve an all active topology (which is what I assume you are looking for). You would need to ensure that one port from each PortChannel is assigned to each VSS member.

You can configure VSS on Cisco 4500E, The Cisco Virtual Switching System is a clustering technology that pools two Cisco Catalyst 4500-E Series Switches with Cisco Catalyst Supervisor Engine 7-E or 7-LE or two Catalyst 4500-X Series Switches into a single virtual switch. In a VSS, the data plane of both clustered switches is active at the same time in both ...

Yes, you can absolutely. You can setup a Port-Channel interface and set it with an IP. This is referred to as a Layer 3 port-channel and you can run routing protocols over it as needed. This will work regardless of if you are running this directly on the same switch or over a mLACP/ vPC. int po1 description Uplink ip address 10.0.1.1 255.255.255.0 no ...

You should never want to update to the latest version just because it is the latest version. In business networks, stability is paramount. The reason for going with a newer version is that it has one or more features which you need which you can't get on the older, more stable version. You need to weigh the the required feature(s) with the possibility of ...
