Certified Directory

Certified Directory

Intended for: Reliable, Tested configuration and image files. The switch will roll back to this software in the event of a system software error.

On reload: By default, the switch will use the software in this directory if there are any differences between the Working and Certified directories.

Saving changes: You cannot save config- uration changes to the Certified directory. To save your changes, be sure that your switch is operating from the Working directory.

The software in the /flash/certified directory should be treated as the “gold master” for the switch. When you place configu- ration and image files in this directory, you are “certifying” them as tested and reliable. If the switch is running from the /flash/working directory and experiences a software problem, it will “roll back” to the last known good software in the /flash/certified directory on the next reboot.

How can I tell which directory the switch is currently using?

When you first boot the switch, the /flash/working directory is used; this allows you to save your initial configuration changes to the boot.cfg file. However, subsequent boots may result in your switch running from the /flash/certified directory. There- fore, verifying the current running directory is a key step any time you are configuring or monitoring the switch.

View the switch’s current running directory by entering the show running-directorycommand. For example:

-> show running-directory

 

CONFIGURATION STATUS

: PRIMARY,

Running CMM

CMM Mode

: DUAL CMMs,

Current CMM Slot

: 1,

Running configuration

: WORKING,

Certify/Restore Status

: CERTIFY NEEDED

SYNCHRONIZATION STATUS

: SYNCHRONIZED,

Flash Between CMMs

Running Configuration

: NOT AVAILABLE,

Stacks Reload on Takeover: ALL STACKs (SW Activation)

In this example, the switch is using the /flash/working direc- tory. For more information on the show running-directorycommand output, refer to the “CMM Commands” chapter in the OmniSwitch CLI Reference Guide.

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.
