Difference between Stacking and Clustering on Cisco switches

Stacking Vs Clustering

I covered the difference between Stacking and Clustering on Cisco Switches and it also applicable to all other vendor switches.





1 Stacking is a dedicated high performance but interconnecting desktop switches in single wiring closet, single point of authentication and management of desktop switches (single IP address) Clustering is a logical collection of switches independent of hardware interconnect method, single point of authentication and management with no physical boundary.
2 It isolated to the single wiring closet It extends beyond  wiring closet
3 It will not support for the legacy systems. It will support for the legacy systems.
4 It will support limited number of switches for stack It will support 16 switches per cluster
5 No flexibility in stacking design Admin chooses the cluster members.
6 Easily Scalable Not easily scalable as compared to stacking
7 Single IP address for management It provides single virtual IP address for full cluster management and Web based management.
8  Low entry price and high performance. IP address and port verification.  High entry price and less performance as compared with stacking.
9 Stacking administration like add/delete new switch or troubleshooting is difficult.  Clustering administration is easy; We can troubleshoot the device by using CMS Web based interface.
