8.1.8 Adding a stack link

Adds a new stack link to a stack consisting of one stack link. Before adding a stack link, the following configuration is assumed.

stack enable
switch 1 provision 3660-48xt4qw
switch 2 provision 3660-48xt4qw
   :
   :
interface hundredgigabitethernet 1/0/51
  switchport mode stack
!
interface hundredgigabitethernet 1/0/52
  switchport mode access
   :
   :
interface hundredgigabitethernet 2/0/51
  switchport mode stack
!
interface hundredgigabitethernet 2/0/52
  switchport mode access
!

<Structure of this section>

(1) Check that no cables are connected to the stacking ports you are adding.

Verify that no cables are attached to the ports that you want to add as stacking ports. If a cable is connected, disconnect it before configuring the configuration.

(2) Configuring the Stack Port Configuration

Configures the stacking port configuration to be added. In a model that implements a stack-only port, if the stack functionality is running, the stack port is configured for the stack-only port. Therefore, this operation is not required.

Command examples

(config)# interface hundredgigabitethernet 1/0/52

(config-if)# switchport mode stack

(config-if)# exit

(config)# interface hundredgigabitethernet 2/0/52

(config-if)# switchport mode stack

(config-if)# exit

Configure stacking ports on Ethernet interfaces with switch number 1 and switch number 2.
(config)# save

(config)# exit

Saves the configuration and returns to administrator mode from configuration command mode.

(3) Connections between stacking ports to be added

Cable the additional stacking ports for switch number 1 and switch number 2.
