  2. Ethernet Applications Why are Ethernet Applications Important? • Widely Accepted Industry Standard • Relatively inexpensive • Easy to Install • Reliable and Secure

  3. Ethernet Standards T = Copper 10BaseT – 10Mbps 100BaseT – 100Mbps 1000BaseT – 1000Mbps X = Fiber 100BaseFX - 100Mbps, 1300nm, Multimode 100BaseLX – 100Mbps, 1310nm, Singlemode 1000BaseSX – 1000Mbps, 850nm, Multimode 1000BaseLX – 1000Mbps, 1310nm, Singlemode R = 10G Fiber 10GBase-SR – 10Gbps,850nm, Multimode 10GBase-LR – 10Gbps,1310nm, Singlemode

  4. Ethernet Frame Ethernet Frame Example: • MAC addresses: • 6 octets burned into the device by the device manufacturer. The first 3 octets are the OUI (Organizationally Unique Identifier) the next 3 are anything the manufacturer desires as long as it is unique.

  5. OSI Model Layer 7 Layer 6 Layer 5 Layer 4 Layer 3 Layer 2 Layer 1

  14. Ethernet Switches • Allows Multiple Devices to Communicate using widely accepted Ethernet Standards • Allows for Network traffic management and security • Layer 2 • Unmanaged • Plug and Play • Simple to Connect • No Administrative Control • Managed • Plug and Play • Simple to Connect • Full Administrative Control via CLI or HTTPS GUI

  17. Switch Management Functions • HTTPS server and CLI interface for management functions • 32K MAC address learning /ageing • 4K Unique VLAN groups • Jumbo Frame Support • QOS – allows admin to prioritize and control network traffic. • 8 classes. • RED (random early detection) and WRED (weighted random early detection) – Protocols/algorithms that limit traffic congestion by statistically dropping packets before they reach their thresholds. • Storm control – Limits forwarding of broadcast, multicast, and unicast traffic is traffic exceeds a set threshold. Most useful against DDOS attacks. • Traffic Policing – Allows admin to limit throughput on specific ports • Access control list – used by network admins to limit access to switching operation. • Security - • Port based 802.1x – provides secure access to the network by not allowing a device to access the network until its credentials have been verified by a RADIUS server and granted access. Credentials are username and password and/or digital certificate. • MAC based authentication – Switch performs MD5 authentication against RADIUS server on behalf of clients using their MAC address as username and password

  18. Switch Management Functions (con’t) • Network Management • RSTP / STP - Messages sent between devices on the network that relay network link partner information. Allows management of redundant ports and calculates lowest cost routes. • Loopguard – Shutdowns effected ports when loops are detected. • SNMP – Used by admins for network monitoring and intrusion detection. • Port Mirroring – Used by admins for traffic monitoring and network intrusion detection. • IGMP snooping – Used by admins to restrict multicast traffic to only ports that have requested multicast traffic. • Link Aggregation – bundles up to 4 ports into one logical link to provide 4x throughput. • LACP – Automatic link aggregation setup protocol which uses LACP messages relayed between devices to setup aggregate links. • LLDP – Protocol which exchanges information between devices on network which provides information such as system name, port name, vlan name, ip management address, system capabilities, MAC/PHY information) • Debug • Loop Detection Restore to Default – Resets switch to factory defaults if loop detected between ports 1 and 2 upon restart. • System log
