Incompatible Software and Stack Member Image Upgrades
You can upgrade a switch that has an incompatible software image by using the
copy {active |
backup} unit://unit-number/{active | backup}
command from config stack mode. It
copies the software image from an existing stack member to the one with incompatible software.
Because that switch does not automatically reload, issue a reload command to that switch and it joins
the stack as a fully functioning member.
Switch Stack Configuration Files
The configuration files record settings for all global and interface specific settings that define the
operation of the stack and individual members. Once a save to the configuration is issued, all stack
members store a copy of the configuration settings. If a stack manager becomes unavailable, any stack
member assuming the role of stack manager will operate from the saved configuration files.
When a new, out-of-box switch joins a switch stack, it uses the system-level settings of that switch
stack. If the switch to store this system-level configuration, you must issue the following command:
copy system:running-config nvram:startup-config
(in Privileged EXEC)
This will save passwords and all other changes to the device.
If you do not save the configuration by doing this command, all configurations will be lost when a power
cycle is performed on the networking device or when the networking device is reset.
Note
After downloading a configuration file to a stack, you must perform a configuration save
operation from the 200 Series user interface (that is, the
copy
command shown above) to
distribute this configuration to non-management units in the stack. This is also true of SSH
key files and SSL certificate files. From the command line interface, the following command
can be used:
copy system:running-config nvram:startup-config (in Privileged EXEC)
You back up and restore the stack configuration in the same way as you would for standalone switch
configuration.
Switch Stack Management Connectivity
You manage the switch stack and the stack member interfaces through the stack manager. You can use
the web interface, CLI, and
. You cannot manage stack members on an individual switch basis.
Connectivity to the Switch Stack through Console Ports
You can connect to the stack manager through the console port of the stack manager only.
