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.
Note 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.
Beginning in privileged EXEC mode, follow these steps to configure the NVRAM buffer size:
This example shows how to configure the NVRAM buffer size:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# boot buffersize 524288
Switch(config)# end
