DRAM (Dynamic Random Access Memory) is a type of volatile memory used in Cisco routers to store data and instructions. It is important to check DRAM regularly to ensure that it is functioning properly and to identify any potential issues.
There are several ways to check DRAM in a Cisco router. One common method is to use the “show memory” command. This command will display information about the DRAM modules installed in the router, including their size, speed, and utilization. Another method is to use the “debug memory” command. This command will provide more detailed information about DRAM activity, including errors and warnings.
