Field

Value

 

 

 

 

 

 

 

 

Size(b)

Amount of memory in the file system in bytes.

 

 

 

 

 

 

Free(b)

Amount of free memory in the file system in bytes.

 

 

 

 

 

 

 

 

Type

Type of file system.

 

 

 

 

 

flash—The file system is for a flash memory device.

 

 

 

network—The file system is for a network device.

 

 

 

nvram—The file system is for a nonvolatile RAM (NVRAM) device.

 

opaque—The file system is a locally generated pseudo file system (for example, the system) or a download

 

interface, such as brimux.

 

 

 

 

 

unknown—The file system is an unknown type.

 

 

 

 

 

 

 

Flags

Permission for file system.

 

 

 

 

ro—read-only.

 

 

 

 

 

rw—read/write.

 

 

 

 

 

wo—write-only.

 

 

 

 

 

 

 

 

 

 

Prefixes

Alias for file system.

 

 

 

 

 

flash:—flash file system.

 

 

 

 

 

ftp:—File Transfer Protocol (FTP) network server. Used to transfer files to or from the network device.

 

nvram:—Non-volatile RAM memory (NVRAM).

 

 

 

null:—Null destination for copies. You can copy a remote file to null to determine its size.

 

rcp:—Remote Copy Protocol (RCP) network server.

 

 

 

system:—Contains the system memory, including the running configuration.

 

tftp:—Trivial File Transfer Protocol (TFTP) network server.

 

zflash:—Read-only file decompression file system, which mirrors the contents of the flash file system.

 

 

 

 

 

 

Setting the Default File System

You can specify the file system or directory that the system uses as the default file system by using the cd filesystem: privileged EXEC command. You can set the default file system to omit the filesystem: argument from related commands. For example, for all privileged EXEC commands that have the optional filesystem: argument, the system uses the file system specified by the cd command.

3200 specifications

Cisco Systems 3200 Series routers are designed to deliver high-performance, reliable networking solutions for enterprise and service provider environments. They are part of Cisco's extensive portfolio that addresses the challenges of modern networking, particularly in connecting remote offices and branch locations efficiently and securely.

One of the standout features of the Cisco 3200 Series is its scalability. The routers support a variety of modular interfaces, allowing organizations to tailor their network infrastructure according to specific needs. This modularity ensures that as businesses grow and their networking requirements evolve, the Cisco 3200 can adapt without necessitating a complete overhaul of existing hardware.

Security is another critical characteristic of the Cisco 3200 routers. They incorporate robust security features such as integrated firewall capabilities, advanced encryption standards, and Virtual Private Network (VPN) support. This ensures that sensitive data transmitted over the network is protected from potential threats, making them ideal for businesses that prioritize security, especially in regulated industries.

Performance-wise, the Cisco 3200 is equipped with advanced processing capabilities, enabling it to handle high data throughput even in demanding environments. This performance is bolstered by the use of Cisco's proprietary technologies, such as Quality of Service (QoS) and traffic shaping, which allow the prioritization of critical applications to ensure seamless connectivity.

The router series also benefits from Cisco's extensive software ecosystem, which includes Cisco IOS (Internetwork Operating System). IOS provides a familiar interface for network administrators, alongside a wealth of features for configuration and management. Furthermore, the Cisco 3200 Series is designed to integrate with Cisco's Application Policy Infrastructure Controller (APIC) and Software-Defined Networking (SDN) solutions, offering enhanced flexibility in managing network resources.

Connectivity options for the Cisco 3200 Series are extensive, offering support for various WAN technologies, including MPLS, LTE, and broadband internet. This versatility enables organizations to choose the best connectivity solutions according to their geographic and operational requirements.

Finally, the Cisco 3200 Series routers are built with reliability in mind. They are designed for high availability and redundancy, ensuring that network services remain uninterrupted in the event of hardware failures or maintenance activities.

In conclusion, Cisco Systems 3200 routers represent a comprehensive networking solution, combining scalability, security, performance, and reliability, making them a preferred choice for organizations looking to enhance their networking infrastructure in a dynamic digital landscape.
