Step 4 Scroll down to External Data Locations and enter the following in the Authentication Server field:

http://<your Cisco Unified CM IP Address>:8080/authenticate.html

Step 5 Scroll down a little bit more to Secure Shell Information and enter your administration username and password.

Step 6 Click Save to save your settings.

Step 7 Go to the top right of the screen to Related Links, choose Subscribe/Unsubscribe Services and click GO.

Step 8 Choose the appropriate MIDlet to download onto the phone. If you are unsure which one you should use, see the Release Notes for Cisco TelePresence System for your release on Cisco.com.

If MIDlets are already installed and you need to make any changes, do the following:

a.Click the link under Subscribed Services and click the Unsubscribe.

b.Choose the appropriate MIDlet in the Select a Service field.

c.Click Next and then Subscribe.

Step 9 Click Reset to reset the phone and save your settings. See the “Managing Phone Reset and Codec Connectivity” section on page 4-13for reset information.

Step 10 Open an SSH client in a browser window and SSH into your phone.

Step 11 When the login: prompt appears, enter the following:

OL-21851-01 specifications

Cisco Systems OL-21851-01 refers to a specific certification exam related to Cisco's networking technologies, particularly within the field of enhanced security and network management. This exam is a part of the Cisco Certified Network Associate (CCNA) certification, designed to validate foundational knowledge and skills required to implement, operate, and troubleshoot small-to-medium sized networks.

One of the main features of the OL-21851-01 exam is its comprehensive coverage of essential networking concepts. Candidates are tested on their understanding of network fundamentals, including OSI and TCP/IP models, IP addressing and subnetting, and different networking protocols. It also emphasizes the importance of identifying and mitigating network vulnerabilities, in light of the increasing need for cybersecurity in modern infrastructures.

The exam incorporates a strong focus on Cisco's proprietary technologies, specifically Cisco IOS, which is the operating system that runs on a wide range of Cisco devices. Understanding Cisco IOS commands and configurations is critical for success in this exam, as they are integral to managing and optimizing network devices.

Another key aspect of OL-21851-01 is the emphasis on automation and programmability within networking environments. Candidates learn about modern automation tools and methods that help streamline network management tasks and enhance operational efficiency. This reflects the industry's shift toward Software-Defined Networking (SDN), which supports the need for flexibility and simplified network operations.

In addition to technical skills, the exam also assesses candidates' ability to implement network security measures. This includes configuring firewalls, access control lists (ACLs), and intrusion prevention systems (IPS) to protect network resources from potential threats. The knowledge of how to monitor and troubleshoot network performance using Cisco tools is also a critical requirement.

To succeed in the OL-21851-01 exam, candidates are encouraged to leverage Cisco's extensive resources, including training courses, study materials, and hands-on labs. Engaging in practical lab scenarios is particularly beneficial, as it allows candidates to apply theoretical knowledge in real-world contexts, reinforcing their skills in network design and management.

In conclusion, Cisco Systems OL-21851-01 is an essential certification for aspiring networking professionals, providing a robust foundation in networking principles, security practices, and modern automation techniques that are pivotal for managing today’s complex networking environments effectively.
