Boot and Image Files

Although the flash memory on OmniSwitch 6850 Series switches can contain many file types (e.g., log and snapshot files), there are four specific file types that provide key switch and network functions. These files include the boot.cfg file, boot.params file, boot.slot.cfg file, and image (.img) files.

boot.params File

The boot.params file provides IP address, gateway, and mask information for the switch. This information is required for Ethernet connections to the switch.

This file also contains default console port parameters (baud rate, etc.) and can be modified via the modify boot parameters CLI command.

In order to be read by the switch, the boot.params file must be placed in the /flash directory. If the file is deleted for any reason, a new boot.params file will be automatically gener- ated on the next system boot. However, all user-configured information, such as IP address, gateway, and mask informa- tion, will be lost. Therefore, it is recommended that you keep a backup copy of this file at all times.

boot.cfg File

The boot.cfg file stores your network configuration parame- ters. When you first boot the switch, no boot.cfg file is present. This file is automatically generated when you first issue a write memory command to save your configuration changes. The file is then automatically placed in the /flash/working directory.

Important. Your switch must be running from the /flash/working directory in order to save changes to the boot.cfg file. Refer to “Working and Certified Directo- ries” on page 22 for more information.

Once the configuration parameters stored in the boot.cfg file are considered tested and reliable, the file can be copied to the /flash/certified directory and become part of the “last known good” software for the switch.

If all copies of this file are deleted and a system boot occurs, your network configuration will be lost. Therefore, it is recom- mended that you keep a backup copy of this file at all times.

6850-24, 6850-P24X, 6850-P48X, 6850-P48L, 6850-48 specifications

The Alcatel-Lucent 6850 series switches, comprising the 6850-U24X, 6850-48X, 6850-P24, 6850-P48, and 6850-P24L, represent a key advancement in network infrastructure solutions, delivering reliable performance and flexibility for various enterprise networking environments. These switches are designed to meet the needs of both wired and wireless networks, offering an array of features tailored for modern data traffic demands.

One of the standout features of the 6850 series is its Layer 2 and Layer 3 capabilities, allowing for advanced VLAN management and routing functionalities. This ensures seamless communication across multiple devices and subnets while improving overall network efficiency. The switches support a variety of routing protocols such as OSPF, RIP, and PIM, facilitating optimized path selection and load balancing.

The 6850-U24X model features 24 ports with 10 Gigabit Ethernet capabilities, enabling high-speed connections for bandwidth-intensive applications. The 6850-48X, on the other hand, boasts 48 ports, accommodating larger connectivity needs without compromising performance. Meanwhile, the 6850-P24 and 6850-P48 variants are geared towards Power over Ethernet (PoE) applications, providing up to 30W per port to power devices like IP cameras and wireless access points, simplifying installations.

Another key characteristic of the 6850 series is its energy efficiency. These switches incorporate intelligent power management features that help organizations reduce their carbon footprint and operational costs. This is further enhanced by the switches' ability to support Energy Efficient Ethernet (EEE), leading to reduced power consumption during low-traffic periods.

The series also supports advanced security features, including Access Control Lists (ACLs), DHCP snooping, and dynamic ARP inspection, which collectively protect against unauthorized access and cyber threats. The built-in redundancy features, such as link aggregation and Spanning Tree Protocol (STP), ensure high availability and network resilience.

In terms of software capabilities, the Alcatel-Lucent 6850 switches are compatible with the Nuage Networks SD-WAN solutions, enabling organizations to leverage software-defined capabilities for greater agility and simplified network management. Furthermore, the switches support flexible stacking options, allowing multiple units to operate as a single logical entity, enhancing scalability and simplifying management.

Overall, the Alcatel-Lucent 6850 series switches offer a balanced blend of performance, flexibility, and security, making them an ideal choice for enterprises looking to enhance their networking capabilities. Their comprehensive feature set positions them as robust solutions for managing contemporary networking challenges.
