Stacking and High Availability Cisco
De Linuxmemo.
Any 10G port of the switch can be used for stacking. At least two ports must be chosen for stacking in a given switch. Some switches have their stack LEDs numbered 1, 2, 3, and 4 to indicate Active, Standby, and Member while the others types use the system LED flashing behavior to describe the same thing.
- Native Stacking- The switch is part of a stack in which all of the units are of the same type.
- Hybrid Stacking – The switch is part of a stack that can consist of either mixed type of CBS350 devices.

[modifier] les membres
- Active switch, or commander.
The Active switch is a switch in the stack that handles the configuration for the entire stack.
- Standby switch
is a switch that will become the new Active switch if the original Active switch goes offline.
- Member
is a stackable switch that operates as an additional unit within the stack.
(A stack port is a port on the switch that is used to communicate with other switches in the stack. Depending on the model, a switch can have either preconfigured or user-defined stack ports.)
[modifier] Switch Stack Configuration Files
The configuration files record these settings:
- System-level (global) configuration settings—such as IP, STP, VLAN, and SNMP settings—that
apply to all stack members
- Stack member interface-specific configuration settings, which are specific for each stack member

[modifier] Configuration
1)Active
configure stack unit 1 stack configuration links te1 , te5 unit-id 1 end show stack configuration copy running-config startup-config reload
2)Standby or Member Switch
configure stack unit 1 stack configuration links te1 , te5 unit-id 2 end show stack configuration copy running-config startup-config reload
3)Active
show stack show stack links [details] (Optional) To access the Standby switch, enter the stack unit ID of the switch in the Global Configuration context by entering the following: stack unit 2
