Cisco Switch: Guide to buiding stackings systems for 2 Cisco switch 9300 devices

Overview

Stacking switch is a technology that allows multiple switches to be gathered together, allowing the management of a swicth group like a switch. This is technology that allows failover between switches without downtime

Strengths

• Central management
• The ability to add 1 switch to stack
• Redundancy and high availability for each member in the stack, any switch in stack down does not affect the entire stack. Even more than one member down
• With stack we can increase the member in the stack without losing the simplicity of the model
• Don’t loop

Cons

• The wiring between switches in the stack is a dedicated wire
• Switches in the same stack must be placed close together
• High cost
• The maximum number of members in the stack is 9

Stack Member Priority Values

Stack members with the highest Priority index will have a high percentage voted active switch. This priority index is valid from 1 to 15. The default priority value is 1, you can check this through the show switch statement

Configure Stack Switch

• Persistent MAC Address activation: When this feature is activated, there is a warning about the consequences of this feature. When this feature is activated, there will be a delay before the stack’s MAC address switches to the MAC address of the new active switch

• Set up priority indicators for stack members

switch stack-member-number priority new-priority-number

• Delete 1 switch from stack

Remove the cable stack, and connect the cable between the remaining members in the stack, then use the command: no switch stack-member-number provision

• Check and upgrade in in compatibility switches in stack
