Memory Types in Cisco Routers

To fully appreciate the role of NVRAM, it’s helpful to understand the different types of memory found in Cisco routers:

* ROM (Read-Only Memory): This is typically the boot firmware.ROM, RAM, NVRAM and Flash Memory on Cisco Routers It’s non-volatile and holds the boot loader and basic diagnostic programs.

* RAM (Random Access Memory) / DRAM: This is the volatile memory used to store the running configuration, routing tables, ARP cache, and other dynamic dataThese devices offer 4-GB DRAM/8-GB flash and 8-GB DRAM/16-GB flash options. There is only one WAN interface combination in the 1131 models, with the option for .... When the router is powered off, the contents of RAM are lost. The Cisco 871 commonly comes with a default of 128 MB of DRAM.

* NVRAM (Non-Volatile Random-Access Memory): This is where the startup configuration is saved. It’s non-volatile, meaning it retains its data even when the router is powered off. When the router boots up, it loads the startup configuration from NVRAM into RAM to become the running configuration.2011年8月15日—After the supervisor is up, use cut and paste or the tftp command to copy the configurations to the supervisor engine and then toNVRAM. Step 3. The Cisco 871 router's NVRAM plays a vital role in ensuring that your network configurations are persistent.

* Flash Memory: This is used to store the Cisco IOS (Internetwork Operating System) software image. It's also non-volatile and can be Field-Programmable. The Cisco 871 typically ships with 24 MB of flash memory, which can be expanded up to a maximum of 52 MB.

The Role of NVRAM in the Cisco 871

The router's NVRAM on the Cisco 871 is absolutely critical for maintaining the device’s operational state across reboots. When you make configuration changes and execute the `copy run start` command, the running configuration from RAM is saved to NVRAM. This ensures that upon the next reboot, the router will load the exact configuration you previously set.2024年9月4日—The front of the chassis hasfour pluggable Modular Port Adapters (MPAs) slots. ... Airflow Direction for Cisco 8712-MOD-M Router in PSE ... Without persistent storage like NVRAM, you would have to reconfigure the router from scratch every time it was powered on, which would be highly impractical.

While the Cisco 871 router does not have separate, physical NVRAM slots, it does have integrated NVRAM that serves its purpose for storing configurations. Data sheets for other series, such as the Cisco 8700 Series Routers Data Sheet mentioning four pluggable Modular Port Adapters (MPAs) slots, refer to expansion for network interfaces, not memory modules like NVRAM. Similarly, discussions about other Cisco products might mention Six-slot chassis like the Cisco ASR 9006, which are designed for much larger deployments and offer extensive modularity, but this is distinct from the integrated memory architecture of the 871.

For the Cisco 871 and similar access routers, understanding which types of memory are upgradeable is also important. While NVRAM is integrated and not user-upgradeable in the traditional sense, it is possible to upgrade the DRAM and Flash Memory on some Cisco 800 series routers.While theCisco 871 routeritself doesn't have dedicated "slots... Therouter's NVRAMis essential for storing the configuration, and unlike flash memory ... For instance, the 871w can accept specific types of SDRam DIMMs4 modular port adapter slots at 1.6Tbps capacity each. 8711-32FH-M router. 8711-32FH-M front view. Related image, diagram or screenshot. Figure 1. 8711-32FH-M .... It's crucial to consult the specific model's documentation for compatibility, as not all memory upgrades are supported, and using incorrect memory such as alternative sizes of DIMMs will prevent the router from functioning.

In summary, when considering how many NVRAM slots in Cisco 871 router, it’s essential to recognize that this particular model utilizes integrated NVRAM.Cisco 1000 Series Integrated Services Routers Data Sheet This means there are no external or modular slots dedicated to NVRAM expansion. The focus for this router is on its integrated switching capabilities, WAN interface, and the reliable storage of its configuration via its internal NVRAM.
