Don’t Panic for ICND 1 Simualtion questions.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

One of my colleagues went for the ICND 1 (640-822) exam and he failed to pass the exams with a small margin. He got few simulation questions, in which he was suppose the find out the IP address for the router interfaces connected in the topology provided. The show running command was disabled, he was suppose to use alternative IOS commands to determine the IP address assigned to the router interface.

 

In this scenario don’t panic,  the best command to determine the IP address assigned to interface s in any router is “show ip interface brief” or Show ip interfaces. Here is the sample output of these commands

 

ITKE-DAC-3745R01#sho ip interface brief

Cisco Systems released Cisco® IOS® Software updates for Cisco Catalyst® 3750-E, 3750, 3560-E, 3560, and 2960 Series Catalyst Switches

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Cisco Systems announces the release of Cisco IOS ® Software Release 12.2(50)SE for Cisco Catalyst 3750-E,3560-E,3750,3560 and 2960 Series Switches. This new release from Cisco Systems introduces Energy wise technology and adds several enhancements in the areas of identity-based networking services and ease of use with Auto Smart ports.

Picture Courtesy:Cisco Systems.

There are several new features included in this release, which are as following.

• Cisco EnergyWise: The inclusion of Cisco EnergyWise technology in this release enables companywide optimization of greenhouse gas (GhG) emissions by measuring, reporting, and reducing energy consumption across the entire corporate infrastructure.

• Identity-based networking: This release continues to enhance Cisco Identity-based Networking Services (IBNS) with several primary innovations to simplify configurations that support heterogeneous endpoint device environments. The release also includes innovations to transparently integrate with existing network and Internet Protocol Telephony (IPT) infrastructure and to provide IT administrators comprehensive policy enforcement options. These enhancements are covered in detail under “Security and Identity Enhancements” section.

• Auto Smartports: This release extends Smartports to allow dynamic switch port provisioning. The switch uses Cisco Discovery Protocol to determine the type of the device connected to the switch and automatically provisions the port based on the predefined macros. The switch integrates with RADIUS for device authentication and applies the macro based on the RADIUS-assigned tag.

• Wired location services: This enhancement enables switch port tracking of hosts or users connected to switches. As part of the location service, the switch integrates with Cisco wireless Mobility Services Engine, which can be used for host/user lookup in determining the switch connectivity for troubleshooting purposes.

• Cisco Catalyst 3750 Series with Cisco StackWise® enhancements for troubleshooting: This release provides new command-line interface (CLI) for StackWise stats and counters to aid in troubleshooting.

• LLDP-MED integration for class of service/diff services code point (CoS/DSCP): Switch will signal CoS/DSCP settings to connected IP telephone using Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED) (so that the IP telephone can use the values for communication)

• Link Layer Discovery Protocol (LLDP) MIB: This release provides manageability for LLDP including local and remote MIBs.

• Secure copy (SCP) support for Configuration Copy Management Information Base (Config-Copy-MIB). This feature provides secure configuration copy capability.

• IP Source Guard (IPSG) and Dynamic Address Resolution Protocol (ARP) Inspection (DAI) support for Cisco Catalyst 2960 Series Switches with LAN Base software: This release introduces IPSG and DAI capabilities for Layer 2 security.

• Cisco Catalyst 2960 Series authentication-failed VLAN. This feature is now also available in LAN Lite package. Previously it was available only in LAN Base package.

• Cisco Configuration Engine support: Catalyst switches can be managed from Cisco Configuration Engine for zero-touch deployment.

• IS-ISv4: This release introduces Integrated Intermediate System-to-Intermediate System (IS-IS) routing protocol for IPv4 networks.

• RADIUS Server load balancing: This release allows access and authentication requests to be distributed evenly across all RADIUS servers in a server group.

• Cisco Entity Sensor MIB: This release adds manageability for Digital Optical Monitoring (DOM)-capable modules.

• Small Form-Factor Pluggable (SFP) + 10 Gigabit Ethernet X2: This release supports SFP-10G-SR and SFP-10G-LR SFP+ transceiver modules.

• X2 ZR: This release supports 10 Gigabit Ethernet X2 ZR optical modules.

• CPU utilization threshold: This release allows users to define thresholds and receive notification when thresholds are exceeded.

• Embedded Event Manager (EEM) 2.4: This release adds EEM 2.4 support.

• Support for 64 EtherChannel ports: This release increases EtherChannel scaling to 64 per switch. Available only on Cisco Catalyst 3100 Series blade switches

• Resilient Ethernet Protocol (REP) for the Cisco Industrial Ethernet (IE) 3000 Series: This protocol provides fast convergence for Layer 2 ring topologies.

• IPv6 packaging changes: Cisco has announced the end of life for Advanced IP Services (AIS). Functionality previously available in AIS has been migrated to IP Services or IP Base as documented in Table 1.

Cisco brings security to life with animated characters

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Cisco has appointed a select group of Cisco Engineers to develop a state-of-the-art security force. ‘The Realm.” growing beyond the systems in which they were created into a group of powerful defenders. Forming a unified league of security, the defenders battle Botnets, Malware, Spam and Intruders in the Realm, assuring the safety and security of every citizen on the human network.

‘The Realm.”is an online comic that animates the pane flow and adds voice narration. Creatively it’s an engaging experience, not as complete as a full scale animation but more alive that just a flat 2D image.

Visit http://www.cisco.com/go/realm to learn more.

VLAN Trunking Protocol (VTP) Overview – Series 4

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

What do you think what happens? If a new Cisco Catalyst® switch is placed between any two VTP domains, the Cisco Catalyst® switch will join the VTP domain identified by the first VTP update it receives. Just check the below example.

 

 

The VTP domain can be changed to another in a Cisco Catalyst® switch by using the CLI prompt, this is the only way you can change.

Review for CCENT 640-822 Network Simulator

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

CCENT 640-822 Network Simulator is a simply great simulator for the CCNA Certification aspirers covering all the ICND1 topics.

 The  state-of-the-art, interactive simulation software enables you to practice your networking skills with 98 structured labs designed to help you learn by doing, which is the most effective method of learning.

The CCENT 640-822 Network Simulator is divided into three categories, Skill Builder, Configuration Scenario and Troubleshooting Scenario.   The best part of the CCENT 640-822 Network Simulator is its very fast consumes less CPU processing power & it’s a java based application. The lab scenarios included in the CCENT 640-822 Network Simulator are far more complex, challenging you to learn how to perform realistic network configuration and troubleshooting tasks. The CCENT 640-822 Network Simulator is best for the CCNA Certifications aspirers especially for the guys who have less exposure to real environment.

The best thing about the CCENT 640-822 Network Simulator is the organization of labs. The Skill builder consists of three parts; even the Configuration Scenario consists of three parts where as Troubleshooting scenario has one part. These labs are quite handy and useful. The moment you open any lab the corresponding pdf file opens with the lab instructions. You are supposed to answer few questions in the labs, the LAB topology is explained well.

I would strongly recommend the CCENT 640-822 Network Simulator for anyone who is depended on the self study. CCENT 640-822 Network Simulator is available only as a download, and is a subset of the CCENT 640-822 Network Simulator, covering all the ICND1 topics.
