Chapter 7 Managing Firmware and Configurations

Working with Software Images

RCP requires a client to send a remote username on each RCP request to a server. When you copy an image from the WMIC to a server by using RCP, the Cisco IOS software sends the first valid username in this list:

•The username specified in the archive download-swor archive upload-swprivileged EXEC command if a username is specified.

•The username set by the ip rcmd remote-usernameusername global configuration command if the command is entered.

•The remote username associated with the current TTY (terminal) process. For example, if the user is connected to the router through Telnet and was authenticated through the username command, the WMIC software sends the Telnet username as the remote username.

•The WMIC hostname.

For the RCP copy request to execute successfully, an account must be defined on the network server for the remote username. If the server has a directory structure, the image file is written to or copied from the directory associated with the remote username on the server. For example, if the image file resides in the home directory of a user on the server, specify that user’s name as the remote username.

Before you begin downloading or uploading an image file by using RCP, do these tasks:

•Ensure that the workstation acting as the RCP server supports the remote shell (rsh).

•Ensure that the WMIC has a route to the RCP server. The WMIC and the server must be in the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to the RCP server by using the ping command.

•If you are accessing the WMIC through a Telnet session and you do not have a valid username, make sure that the current RCP username is the one that you want to use for the RCP download. You can enter the show users privileged EXEC command to view the valid username. If you do not want to use this username, create a new RCP username by using the ip rcmd remote-usernameusername global configuration command to be used during all archive operations. The new username is stored in NVRAM. If you are accessing the WMIC through a Telnet session and you have a valid username, this username is used, and there is no need to set the RCP username. Include the username in the archive download-swor archive upload-swprivileged EXEC command if you want to specify a username only for that operation.

•When you upload an image to the RCP to the server, it must be properly configured to accept the RCP write request from the user on the WMIC. For UNIX systems, you must add an entry to the

.rhosts file for the remote user on the RCP server. For example, suppose the WMIC contains these configuration lines:

hostname ap1

ip rcmd remote-username User0

If the WMIC IP address translates to ap1.company.com, the .rhosts file for User0 on the RCP server should contain this line:

ap1.company.com ap1

For more information, refer to the documentation for your RCP server.

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.
