Cisco 2960 Stack Module Comparison

by PivIT Global, on Jan 30, 2019 1:33:08 PM

A 2960X switch stack is a set of up to eight stacking-capable switches connected through stacking ports. The entire stack member should use the same IOS version for implementation. How can we know the key stacking modules for Catalyst 2960X switches? Which one is best for your specific needs? In this article we will discuss and compare key features of stacking 2960X switches.

 

Generally, you can stack up to 8 2960-X Switches. When inserting the switches, power down the switch, remove the blanking plate and fit the module in the slot, and install the switch. When power is restored you can use a ‘show inventory’ command to make sure the module has been installed correctly and detected.

 

Cable and stack module

 

 

Below are the types of key stacking modules of Catalyst 2960-X and Catalyst 2960-XR Series:

  • C2960X-STACK: Catalyst 2960-X FlexStack Plus Stack Module
  • C2960X-FIBER-STK (Latest): Catalyst 2960-X FlexStack-Extended Stack Module
  • C2960X-HYBRID-STK (Latest): FlexStack-Extended Hybrid Module

Here are some of the detailed features of these stacking modules:

· C2960X-STACK

· C2960X-FIBER-STK

· C2960X-HYBRID-STK

 

1) FlexStack-Plus Module (C2960X-STACK)

The FlexStack-Plus module is hot swappable and it can be added to any Cisco 2960-X or Catalyst 2960-XR with a FlexStack-Plus slot. It will automatically upgrade to the stack’s Cisco IOS Software version and transparently join the stack switch. In this module you can connect stacking only over copper and provides high bandwidth of up to 80 Gbps between the short distances. The stacking cable for this module is of 0.5m, 1m and 3m length.

Below are the cable product ID along with length:

· CAB-STK-E-0.5M= [1.5-ft]

· CAB-STK-E-1M= [3-ft]

· CAB-STK-E-3M= [10-ft]

1.1 Stacking with FlexStack-Plus Modules

We can stack between 8 2960-X Switches together through FlexStack-Plus modules. The ring topology helps to ensure redundancy for stacking between the switches.

2) Cisco FlexStack-Extended Fiber Module (C2960X-FIBER-STK)

This module allows stacking over Fiber SFP ports. It can provide stacking bandwidth up to 40 Gbps over long distance (Distance limit is base on SPF+ Transceiver). This is not capable with 2960-S switches. It can be stack switches on different floors and building within the campus. Distance all depends upon your fiber cable and SFP+ capabilities.

The FlexStack-Extended has two SFP+ ports in the module. SFP+ is supported on both ports. Chooses best appropriate SFP+ transceivers for your network and SFP+ based on the distance required between switches. PivIT Optics is a great option when it comes to compatible optical transceivers and are a fraction of the cost of OEM transceivers with no los in compatibility or functionality.

With FlexStack-Extended fiber Modules, the Individual Cisco Catalyst 2960-X or 2960-XR Series Switches can connect even when placed on different floors or in different buildings. Up to eight switches can be stacked together through Fiber module. Stacking bandwidth is up to 40 Gbps.

 

Example of stacking between different floors of a building:

3) FlexStack-Extended Hybrid Module (C2960X-HYBRID-STK)

The FlexStack-Extended hybrid module has one SFP+ port and one copper FlexStack-Plus port as shown in the picture below.

The SFP+ port allows stacking over long distances (Distance depends upon your SFP+).

The second copper port allows us to stack switch with FlexStack-Plus. The copper port support under mentioned cable for stacking.
