Considerations About Using Clear Config in a Stack
2-4 Configuring Switches in a Stack
To create a virtual switch configuration in a stack environment:
1. Display the types of switches supported in the stack, using the show switch switchtype
command (page 2-7).
2. Using the output of the show switch switchtype command, determine the switch index (SID)
of the model of switch being configured.
3. Add the virtual switch to the stack using the set switch member command (page 2-11). Use
the SID of the switch model, determined in the previous step, and the unit ID that you want to
assign to this switch member.
4. Proceed to configure the ports of the virtual switch as you would do for physically present
devices.
Considerations About Using Clear Config in a Stack
When using the clear config command (page 3-49) to clear configuration parameters in a stack, it
is important to remember the following:
•Use clear config to clear config parameters without clearing stack unit IDs. This command
WILL NOT clear stack parameters or the IP address and avoids the process of renumbering
the stack.
•Use clear config all when it is necessary to clear all config parameters, including stack unit
IDs and switch priority values. This command will not clear the IP address nor will it remove
an applied advanced feature license.
•Use clear ip address to remove the IP address of the stack.
•Use clear license to remove an applied license from a switch.
Configuration parameters and stacking information can also be cleared on the master unit only
by selecting the “restore configuration to factory defaults” option from the boot menu on switch
startup. This selection will leave stacking priorities on all other units.
Issues Related to Mixed Type Stacks
Feature Support
Because the SecureStack C2 and C3 switches have different hardware architectures, the
functionality supported by the two switch types is different. When the two types of switches are
mixed in a stack, the functionality supported will be the lowest common denominator of features
supported on all platforms. Refer to the firmware Release Notes for information about supported
features.
Configuration
Common Firmware Version
Mixed stacking is supported by SecureStack C2 firmware version 5.02.xx.xxxx only. You can install
the C2 firmware first, with the C3 switch in stand-alone mode, or you can add the C3 switch to the
Note: If you preconfigure a virtual switch and then add a physical switch of a different type to the
stack as that unit number, any configured functionality that cannot be supported on the physical
switch will cause a configuration mismatch status for that device and the ports of the new device will
join detached. You must clear the mismatch before the new device will properly join the stack.
