With all of the innovation taking place in their company, two of the highlights from Cisco Live are that fundamental Networking is more important than ever, and CyberSecurity is a foundational skill in every Cisco environment. This is valuable career information for those building their path in tech.
Clearing the access-list (ACL) counters is similar to resetting the trip odometer on your car and provides a clean slate for future reports. When making changes to the configuration, starting the ACL counters at zero grants more reliable data in relation to the current changes. A reset command must be performed within the CONFIG mode in order to restart that counter, or it won’t work.
To reset the ACL, type the command: “clear access-list counters” in CONFIG mode. Results for the ACL command are now cleared. Use the command: “clear int ethernet0” to clear counters in the interface. It might seem more natural to perform these commands within enable mode, but this only works in CONFIG.
To permanently increase the default terminal length for future IOS sessions, type the following into the console: Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#line vty 04 Router(config-line)#len Router(config-line)#length ? <0-512> Number of lines on screen (0 for no pausing) Router(config-line)#length 40.
Typically, in order to remove unwanted items you have to go through each individual line and put “no” in front. If you need to completely re-do the configuration or are faced with a laundry list of changes, it is simpler and faster to restore the default configuration. Furthermore, it will reduce potential oversight errors.
The data center has become a big differentiator. The more efficiency, the more functionality a company can obtain from its data center the more competitive it can be.
This creates more demand upon the data center for greater agility and flexibility, and more pressure for greater performance and broader capability. Ultimately this results in increased complexity that can make it more and more difficult for a data center to keep up with the constantly growing demand. It becomes a vicious cycle.
This is what inspired Cisco to create the Unified Computing System (UCS). From inception, Cisco described UCS as it’s “end-to-end” solution, bringing every component of the entire compute environment together enabling data center professionals to complete 80% or more of their operational tasks from a single console. Given that IDC reports that the top driver for IT operations and analytics is the requirement for improved infrastructure capacity planning and utilization, having servers, storage, data communications and more all unified under an umbrella of Cisco management tools and systems constitutes a superb solution.
The shift to cloud computing is among the most prolific trends in information technology today. Organizations in both the private and public sectors have already begun migrating applications, services and data to the cloud in an effort to consolidate hardware resources, save money and improve sharing and collaboration capabilities.
The Internet of Things (IoT) is driving recruitment for the larger technology companies. Due to the recent proliferation of IoT enabled devices, including light bulbs, garage door openers and bracelets, the push to connect everything in consumers' homes to the internet is on, and every major developer wants their platform to be the number one, Wired reported. In order to get this to happen, they are plucking the best and brightest out there to join the IoT divisions and head up teams ready to start on IoT projects. It is entirely possibly that Cisco Certified Network Associate (CCNA) training may become even more useful for employees looking to get jobs in all fields with the advent of these new products, as soon all devices will be put on networks, even TVs and mugs.
A new survey has found that almost 60 percent of businesses experienced a malware attack caused by unlicensed software that resulted in loss of data. The report by software lobbying firm BSA and analytics company IDC involved more than 2,000 IT managers in 34 major markets.
A Problematic Shortage
It seems like there is a new cyberthreat announced every day, and that may actually be the case. According to security services provider Symantec, last year saw a 62 percent increase in data breaches, and 2.5 billion records have been exposed in malicious incidents over the past five years. This may be due to the worsening shortage of IT security professionals which, according to estimates from Cisco, has reached one million people.
