20. EtherWAN Features & Applications

22. Total Cost of Ownership can be reduced by creating VLANs (increasing port footprint)

23. Aggregated bandwidth across the network can be controlled

25. Requires more technical knowledge of the user to deploy and maintain

27. Designed to overcome traditional STP and RSTP’s inability to provide fast network recovery and minimize packet loss caused by link failure. α-ring sets the LAST connection as the backup path – ensures no additional packet loss when the ring is restored in < 15ms.

28. SNMP

29. Management tool used for collecting information from, and configuring network devices on an IP network. Use to monitor network performance, detect faults or unauthorized access with minimal impact on network traffic.

30. 802.1p QoS

31. Used to tag frames on an Ethernet frame header in an 802.1 network, and specifies a priority value (0-7, IE: voice / video) to differentiate traffic on the network.

32. 802.1q VLAN Tagging

33. A standard that allows multiple bridged networks to transparently share the same physical network link without leakage of information between networks

34. Port Mirroring

36. Basic function is to prevent bridge loops and broadcast storm(s). Creates spanning tree within a mesh network of connected Layer 2 devices, disables those links that are not part of the spanning tree, leaving a single active path between any two network nodes. Can take 30-50 seconds to respond to a topology change.

37. 802.1w RSTP

38. Allows faster spanning tree convergence after a topology change, the standard network response time is 6 seconds.

39. 802.1s MSTP

40. Merged into 802.1Q (VLAN Tagging)

41. IGMP (Snooping – most requested feature in security applications)

42. Only need for IPv4, IGMP is a communications protocol that is used to manage the membership of IP multicast groups (but does not act as a transport protocol – analogous to ICMP for unicast connections. It allows more efficient utilization of network resources when supporting applications such as streaming video

43. RADIUS Support

45. Command Line Interface – integral to remote device setup, management and troubleshooting

46. 802.1x Security

47. Network protocol that provides an authentication mechanism to devices wishing to attach to a LAN or WLAN, and involves three components: a supplicant, an authenticator (Ethernet switch), and an authentication server. The authenticator acts as a security guard to a protected network area

48. NTP

49. Network Time Protocol – an Internet protocol used to synchronize the switch clock to a time reference, such as the Naval Observatory or GPS source.

50. Built in RTC (real time clock)

51. A clock that is used to time stamp events and statistic logs. The RTC is generally synchronized by NTP so every RTC in a network is in synchronization.

52. Bandwidth Rate Control

53. Allows the user to limit the bit rate on a port by port basis. This is sometimes used to limit the bit rate for a streaming device such as a CCTV camera to prevent it from flooding the network in the event that it malfunctions.

54. MAC-based Trunking

56. Application – Extending network reach over STP
