´        Students learn the basics of routing, switching, and advanced technologies to prepare for the CCENT and CCNA certification exams, networking related degree programs, and entry-level careers.

´        The language used to describe networking concepts is designed to be easily understood by learners at all levels and embedded interactive activities help reinforce comprehension.

´        Courses emphasize critical thinking, problem solving, collaboration, and the practical application of skills.

´        Multimedia learning tools, including videos, games, and quizzes, address a variety of learning styles and promote increased knowledge retention.

´        Hands-on labs and Cisco® Packet Tracer simulation-based learning activities help students develop critical thinking and complex problem solving skills.

´        Embedded assessments provide immediate feedback to support the evaluation of knowledge and acquired skills.

Course Description

CCNA Routing and Switching teaches comprehensive networking concepts, from network applications to the protocols and services provided to those applications by the lower layers of the network. Students will progress from basic networking to more complex enterprise and theoretical networking models later in the curriculum.

 There are four courses in the recommended sequence:

´        Introduction to Networks

´        Routing and Switching Essentials

´        Scaling Networks

´        Connecting Networks

In each course, Networking Academy™ students will learn technology concepts with the support of interactive media and apply and practice this knowledge through a series of hands-on and simulated activities that reinforce their learning.

Introduction to Networks

Description:

Routing and Switching Essentials

Description:

Describes the architecture, components, and operations of routers and switches in a small network. Students learn how to configure a router and a switch for basic functionality. By the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with static route, RIPv2, VLAN, NAT,ACL, DHCP in both IPv4 and IPv6 networks, and perform device discovery, management and maintenance.

Detail:

Determine how a router will forward traffic based on the contents of a routing table.

Explain how switching operates in a small to medium-sized business network.

Use monitoring tools and network management protocols to troubleshoot data networks.

Implement access control lists (ACLs) to filter traffic.

Configure and troubleshoot VLANs and routing with static route and RIPv2.

Describe the operations of Dynamic Host Configuration Protocol for IPv4 and IPv6

Scaling Networks

Description:

Describes the architecture, components, and operations of routers and switches in a large and complex network. Students learn how to configure routers and switches for advanced functionality. By the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with OSPF, EIGRP, STP, and VTP in both IPv4 and IPv6 networks. Students will also develop the knowledge and skills needed to implement DHCP and DNS operations in a network.

Detail:

Configure and troubleshoot DHCP and DNS operations for IPv4 and IPv6

Describe the operations and benefits of the Spanning Tree Protocol (STP)

Configure and troubleshoot STP operations

Describe the operations and benefits of link aggregation and Cisco VLAN Trunk Protocol (VTP)

Configure and troubleshoot basic operations of routers in a complex routed network for IPv4 and IPv6

Configure and troubleshoot advanced operations of routers and implement RIP, OSPF, and EIGRP routing protocols for IPv4 and IPv6

Manage Cisco IOS® Software licensing and configuration files

Connecting Networks

Description:

Discusses the WAN technologies and network services required by converged applications in a complex network. The course enables students to understand the selection criteria of network devices and WAN technologies to meet network requirements. Students learn how to configure and troubleshoot network devices and resolve common issues with data link protocols. Students also develop the knowledge and skills needed to implement IPSec and virtual private network (VPN) operations in a complex network

Detail:

Describe the operations and benefits of virtual private networks (VPNs) and tunneling

describe different WAN technologies and their benefits

Configure and troubleshoot serial connections

Configure and troubleshoot broadband connections

Configure and troubleshoot IPSec tunneling operations

Monitor and troubleshoot network operations using syslog, SNMP, and NetFlow

IPsec VPN Negotiation: CCNA Security Training and Exams

Step 1 - Host A sends interesting traffic to Host B.

Step 2 - R1 and R2 negotiate an IKE Phase 1 session.

Step 3 - R1 and R2 negotiate an IKE Phase 2 session.

Step 4 - Information is exchanged via IPsec tunnel.

Step 5 - The IPsec tunnel is terminated.

Configuring Frame Relay CCNA Training in Faisalabad

Configuring Frame Relay
-------------------------------
Router(config-if)# encapsulation frame relay [cisco | ietf]
Router(config-if)# bandwidth kbps
Router(config-if)# frame-relay lmi-type [cisco | q933a | ansi]
Router(config-if)# frame-relay map [protocol][network address][dlci] broadcast

EtherChannel Configuration

EtherChannel Configuration

           Switch(config)#  interface range fa0/1 – 4 {we can use the range or single interface}

Switch(config-if)#  channel-group [1 – 6] mode [auto | desirable | on | active | passive]

This port-channel can be customized via the CLI:

           Switch(config)# interface port-channel[1 – 6]

           Switch(config-if)# switchport mode trunk {an example only}

However if we wish to view the operation we use the term “etherchannel”.

            Switch# show interface etherchannel

            Switch# show etherchannel [summary | load balance | port-channel]

EtherChannel Requirements CCNA

EtherChannel has specific requirements and additional platform (hardware) related requirements. A partial list is:

·         EtherChannel can have a maximum of eight physical interfaces per port-channel

·         All interfaces within the port-channel must have the same speed and duplex settings

·         An EtherChannel does not form if one interface is a Switch Port Analyzer (SPAN) port

·         An interface within a port-channel cannot be configured as a secure port (do not activate port security)

·         All interfaces within a port-channel must be assigned to the same access VLAN or if they are Dot1q trunks they must be assigned the same native VLAN

·         If interfaces are trunking then they must all have the same allowed range of VLANs

Catalyst 2960 switches can leverage a protocol to dynamically establish and maintain the EtherChannel bundle. The channel-group mode command allows you to decide if the EtherChannel group uses Port aggregation Protocol (PAgP), Link Aggregation Protocol (LACP), or to simply force the interface to channel without PAgP or LACP.  Forcing interfaces to channel may create problems if any interfaces have dissimilar configurations.  PAgP allows the switches to learn the capabilities of each interface assigned to an EtherChannel bundle and reliably activates interfaces of similar configuration to form a port-channel. PAgP transmits and receives messages on all interfaces in the EtherChannel bundle and restricts the PAgP traffic to the native VLAN if the ports are in trunking mode. LACP is similar in operation to PAgP and standards based while PAgP is Cisco proprietary.

Other local link protocols such as DTP, VTP, CDP, and STP still transmit and receive frames over a port-channel. STP only sends frames out the first interface in the port-channel and views the port-channel as a single physical port. Cisco uses Per-VLAN Spanning-Tree (PVST) and if the port-channel is a Dot1q trunk then multiple STP messages might require transmission (with appropriate Dot1q tags).

Spanning-tree reflects the increased bandwidth provided by EtherChannel. The default cost for a 100 Mbps link is 19 and if a port-channel is created that has only two 100 Mbps links the spanning-tree cost will be 9. If more physical ports are assigned to the port-channel the cost decreases. Note: the spanning-tree cost does not dynamically change when links go down or when a link is brought back up within the port-channel; the cost is calculated based on the number of ports assigned to the port-channel.
