Note: You must enter the stack-unit stack-unit stack-group stack-group command when adding units to a stack to ensure the units are assigned to the correct groups. Note: Any scripts used to streamline the stacking configuration process must be updated to reflect the Command Mode change from EXEC to CONFIGURATION to allow the scripts to work correctly. Enable Front End Port Stacking To enable the front ports on an S4810 or S4820T unit for stacking, use the following procedure. Note: Once a port has been allocated for stacking, it can only be used for stacking. If stack-group 0 is One a allocated for stacking, then ports 0, 1, 2, and 3 can be used for stacking but not for Ethernet anymore. If only port 0 is used for stacking, ports 1, 2, and 3 are just spare; they cannot be used for Ethernet. After the front ports are enabled, use the show system stack-unit command to view the port assignments, Task Command Syntax Command Mode Assign a stack group for each unit. Begin with the first port on the management unit. Next, configure both ports on each subsequent unit. Finally, return to the management unit and configure the last port. (See the example below.) Range: 0-15 stack-unit id stack-group id CONFIGURATION Save the stacking configuration on the ports. write memory EXEC Privilege Reload the switch. FTOS automatically assigns a number to the new unit and adds it as member switch in the stack. The new unit synchronizes its running and startup configurations with the stack. reload EXEC Privilege After the units are reloaded, the system reboots. The units come up in a stack after the reboot completes. 922 | Stacking
