Cisco Catalyst 2960 Series User Manual

Configuring the NVRAM Buffer Size
The default NVRAM buffer size is 512 KB. In some cases, the configuration file might be too large to save
to NVRAM. Typically, this occurs when you have many switches in a switch stack. You can configure the
size of the NVRAM buffer to support larger configuration files. The new NVRAM buffer size is synced to
all current and new member switches.
After you configure the NVRAM buffer size, reload the switch or switch stack.
When you add a switch to a stack and the NVRAM size differs, the new switch syncs with the stack and
reloads automatically.
