How do I check the free memory on my Cisco router?

The show memory exec command is often used to check the amount of a router’s free memory. In troubleshooting cases where router performance is the focus, this is a major command used to see the statistics about the router’s memory.

What is DRAM in Cisco router?

DRAM, or Dynamic Random Access Memory caters to two main device requirements. The first of these is known as Processor Memory which is reserved for exclusive access by the CPU, which it uses when executing software running on the Cisco IOS platform.

Is DRAM used for main memory?

DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory. Each DRAM memory cell is made up of a transistor and a capacitor within an integrated circuit, and a data bit is stored in the capacitor.

How much RAM does a router need?

Also, your router should not have less than 128MB of RAM. The ideal would be 256 MB of RAM or more. This is to make sure that it can process everything as fast as possible. If money is not an issue, you should seek a wireless router with 512 MB of RAM or 1 GB.

Is DRAM still used?

DRAM is widely used in digital electronics where low-cost and high-capacity memory is required. One of the largest applications for DRAM is the main memory (called the “RAM”) in modern computers and graphics cards (where the “main memory” is called the graphics memory).

How much rack space is needed for the Cisco ASR 1006 router?

The Cisco ASR 1006 Router requires a minimum of 6 rack units (10.45 inches or 26.6 cm) of vertical rack space. Measure the proposed rack location before mounting the chassis in the rack. Maintain a minimum clearance of 3 inches (7.62 cm) for the front and rear of the chassis for proper chassis cooling.

What is the memory scalability of the ASR 1000 series routers?

The RP offers memory scalability up to 4 GB for ASR1000-RP1 and 16 GB for ASR1000-RP2. Cisco ASR 1000 Series Aggregation Services Routers introduce the Cisco IOS XE Software as their software architecture.

How do I remove the Cisco ASR 1000 series Route processor (RP1)?

To remove the Cisco ASR 1000 Series route processor (RP1 or RP2) from the Cisco ASR 1006 Router, Cisco ASR 1004 Router and Cisco ASR 1013 Router, follow this procedure: Slip on an ESD-preventive wrist strap and attach it to a chassis surface.

Can I upgrade the rp1/rp2 on the asr1002/1002-x?

Note: Cisco ASR 1002,and ASR1002-F have an integrated RP1 built into the chassis that is not upgradable. Note: Cisco ASR 1001, ASR 1001-X, and ASR 1002-X (part numbers ASR 1001, ASR 1001-X, ASR 1002-X) have an integrated RP2 built in to the chassis that is not upgradable.
