What is irSysFlashMemSize?

This OID stores the size of the device's flash memory in megabytes as a text string. Operationally, it tells you how much storage capacity the device has for configuration and firmware. A network administrator uses this to verify the device has adequate storage before upgrading firmware to a newer version.

Examples
