Building a campus network
- Elements of the physical layer.
- From 10MB Ethernet to Gigabit Ethernet.
- Full Duplex Ethernet.
- Principles and protocols.
- Virtual LAN: VLAN.
- VLAN design criteria (ports, addresses).
- Wide area virtual LANs. VLAN Trunking Protocol (VTP).
- Assigning mobile access. Dynamic Trunk Protocol (DTP). Cisco Discovery Protocol (CDP).
- Switch to switch linking. Inter Switch Link (ISL from Cisco) or 802.1.q (IEEE standard).
- Grouping links: Ether Channel.
Hands-on work
Configuring a switched network. Implementing interconneced virtual LANs. VTP configuration.
Managing redundant links
- Spanning Tree Protocol (STP).
- Principles, algorithm.
- Configuring a redundant topology.
- Precautions of use.
- Impact on convergence.
- PVST+ (Per VLAN Spanning Tree), evolution of Spanning Tree.
- InterVLAN routing.
- Defining workgroups.
Hands-on work
Redundant gigabit switch interconnections. Implementing STP. Configuring priorities, managing backups. Handling incidents based on settings.
Traffic management
- VLAN to VLAN traffic.
- Integration via a backbone.
- IP routing performance with multilevel switching.
- Managing storms and corresponding actions.
- Configuration of quality of service for data traffic and VoIP traffic.
- 802.1P service classes and their DSCP mapping.
- Marking flows, prioritization and resource reservation.
- VLAN VoIP.
- Benefits of MPLS (Multi Protocol Label Switching).
- IP Switches.
Hands-on work
Implementing different traffics. Comparing performance.
Adding reliability
- The HSRP protocol (Hot Standby Routing Protocol).
- Implementing a reliable solution.
- Validating handovers.
Hands-on work
Configuring a switch command cluster with HSRP transparent backup. Validating handovers. Configuring priorities and preemption.
Handling multicast.
- Role and principle of multicast.
- Link level processing. Different protocols: IGMP.
- The role of the PIM protocol (ProtocolIndependent Multicast).
- PIM V1 and V2.
- Implementing the IGMP snooping function.
- Management of multicasting.
Hands-on work
Completion and management of multicasting in a switching network.
Network access control
- Filtering mechanisms.
- Traffic filtering.
- Standard and extended lists.
- By address, port, applications, flows.
- Secure ports and associated actions.
Hands-on work
Implementing criteriabased access protections. Filtering physical access attempts. Filtering traffic.
