Unlocking Session Types

Security is a key feature on OmniSwitch 6850 Series switches. As a result, when you access the switch for the first time, you must use a direct console port connection. All other session types (Telnet, FTP, WebView, SNMP, etc.) are “locked out” until they are manually unlocked by the user.

The CLI command used to unlock session types is

aaaauthentication.

Note. When you unlock session types, you are granting switch access to non-local sessions (e.g., Telnet). As a result, users who know the correct user login and pass- word will have remote access to the switch. For more information on switch security, refer to the “Managing Switch User Accounts” chapter of your OmniSwitch 6800/ 6850/9000 Switch Management Guide.

Unlocking All Session Types

To unlock all session types, enter the following command syntax at the CLI prompt:

-> aaa authentication default local

Unlocking Specified Session Types

You can also unlock session types on a one-by-one basis. For example, to unlock Telnet sessions only, enter the following command:

-> aaa authentication telnet local

To unlock WebView (HTTP) sessions only, enter the follow- ing command:

-> aaa authentication http local

You cannot specify more than one session type in a single command line. However, you can still unlock multiple session types by using the aaa authentication command in succes- sion. For example:

-> aaa authentication http local

-> aaa authentication telnet local -> aaa authentication ftp local

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.
