Working and Certified Directories

OmniSwitch 6850 Series switches offer flash memory with

8 MB base ROM space and 64 MB extended ROM. This mem- ory is used to store files, including boot and image files, that are used for switch operations.

The /flash directory contains two subdirectories: /working and /certified. These directories work together to provide the image rollback resiliency feature. Image rollback allows the switch to return to a prior “last known good” version of soft- ware in the event of a system software problem.

Working Directory

Working Directory

Intended for: Files that are being configured and tested. Once these files are considered valid and reliable, they can be copied to the Certified directory.

On reload: If the Working and Certified directories are identical, the switch will automatically run from software in this directory. If the two directories are not identical, you can instruct the switch to run from the Working directory by issuing the reload working command.

Saving changes: You can save config- uration changes to the Working directory via the write memory command.

The /flash/working directory is intended for software that is still being configured for your network. Changes made while configuring your switch are saved to the boot.cfg file in the /flash/working directory.

Once the /flash/working directory’s configuration and image files are road-tested and considered valid and reliable for your network, they can be copied to the /flash/certified directory.

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.
