  1. IEI- What’s New Prepared by: Moxa Net/ Technical Support Date: mm-dd-yyyy

  2. Agenda • Turbo Pack II • Communication Redundancy • VLAN • Time Synchronization • CLI • Traffic Control • EDR-G902 • Smart PoE • MxNVR-IA8 • VPort 364 Confidential

  3. Communication Redundancy Confidential

  4. Spanning Tree Protocol • IEEE 802.1D (1998) • Introduction of Spanning Tree Protocol • IEEE 802.1w (2001): • Rapid Spanning Protocol • Enhancement of STP • IEEE 802.1D-2004 (2004): • Incorporate with RSTP • Obsolete STP

  5. RSTP • Rapid Spanning Tree Protocol • IEEE 802.1D-2004 • Prevent looping • Create loop free network • Block redundant port Root Block

  6. RSTP (IEEE 802.1w)

  7. RSTP (IEEE 802.1D-2004)

  8. RSTP (IEEE 802.1D 2004) • Force Edge • Physical connect-> Forwarding state • For End devices • False • Physical connect-> Blocking state-> BPDU process • For switches • Auto (Default) • Physical connect-> Forwarding state-> detect BPDU-> • Yes-> BPDU process • No-> Forwarding state

  9. STP with VLAN • What will be the communication? PC2 PC1 Root VLAN 1 VLAN 2 PC4 PC3

  10. Root V1 V1 F F F B V2 V2 STP with VLAN • VLAN1 and 2 belong to one single STP • Only 1 forwarding path • Only 1 VLAN communication works at a time!!!

  11. STP with VLAN • VLAN1 and VLAN2 belong to one single STP • VLAN1 and VLAN2 go through Trunk port • Can we separate the VLAN1 & VLAN2 traffic? Root V1 V1 F F Trunk, Fix: V1, V2 V2 V2 F B Trunk, Fix: V1, V2

  12. MSTP • Multiple Spanning Protocol (IEEE 802.1s) • Instance • One Spanning Tree protocol running in one “Instance” • An Instance can have multiple VLANs • A VLAN belongs to one Instance only • Instance 1-16 & CIST • CIST • Common & Internal Spanning Tree • Undefined VLANs • Load Sharing • Different VLAN thru Different Path

  13. V1 V1 F F V1 V1 F F V2 V2 B V2 F V2 F F MSTP 200MB • With MSTP • Without MSTP 100MB

  14. VLAN10 VLAN10 VLAN20 VLAN20 VLAN30 VLAN30 MSTP configuration • Load sharing • Each VLAN goes through different path • Redundancy • Communication still works if any path breaks

  15. MSTP Configuration • VLAN configuration

  16. MSTP Configuration

  17. The Root switch’s MAC of each Instance Select MSTP Must be checked before you activate!!! MSTP Configuration

  18. MSTP configuration • Assign VLANs to each Instance • Instance 01 Select the Instance Add VLAN to the Instance Port Status & Role of each Ins. Enable MSTP

  19. MSTP configuration • Instance 02 • Instance 03

  20. VLAN10 VLAN10 VLAN20 VLAN20 VLAN30 VLAN30 MSTP configuration 2 2 4 4 6 6 Different VLAN go thru different path

  21. MSTP summary • Per Instance, per STP • One Instance can have multiple VLANs • One VLAN belongs to one Instance only • Share the load • Redundancy

  22. VLAN Confidential

  23. VLAN brief • Allows a group of devices communicate to each other as they are in the same physical segment • One VLAN is one broadcast domain • Cross VLAN communication requires Router

  24. Moxa VLAN configuration

  25. Moxa VLAN configuration

  26. Moxa VLAN Port • Access Port • Untagged frame only • For legacy/VLAN unaware Ethernet devices • Ingress & Egress are untagged frame

  27. Moxa VLAN Port • Trunk Port • Untagged & tagged frame • For switch to switch interconnection • Ingress frame • Untagged-> Add PVID to the frame • Tagged-> Frame tag= PVID, or Fixed VLAN (Tagged) • Egress frame • Untagged-> Frame tag= PVID • Tagged-> Fixed VLAN (Tagged)

  28. Moxa VLAN Port • Hybrid Port • Untagged & tagged frame • For VLAN aware or unaware device • Ingress frame • Same as Trunk port • Egress frame • Untagged-> Frame tag= PVID, or Fixed VLAN (Untagged) • Tagged-> Fixed VLAN (Tagged)

  29. Moxa VLAN setup Trunk Hybrid Access VLAN unaware VLAN unaware VLAN aware

  30. Time Synchronization Confidential

  31. NTP Switch as a Client Switch as a Server

  32. PTP version 2 • PTP v2 enhancement • Transparent Clock mode • Smaller packet size- save bandwidth • High data sampling rate- increase accuracy • Wildly used, e.g. IPv4, IPv6, PROFINET,… • New role in PTPv2 • E2E TC • P2P TC

  33. PTP BC & TC • Precision Time Protocol • V1 Boundary Clock (BC) • V2 Transparent Clock (TC) Hieratical Time Sync M S M M S S Transparent Time Sync S M

  35. Sync Sync Follow_up Follow_up End-to-End Transparent Clock • E2E TC • End-to-End Transparent Clock • Master to Slave Offset correction • No Propagation delay of each link Master TC Slave Delay_Req Delay_Req Delay_Resp Delay_Resp

  36. Sync Sync Follow_up Follow_up Delay_Req Delay_Req Delay_Resp Delay_Resp Peer-to-Peer Transparent Clock • P2P TC • Peer-to-peer Transparent Clock • Master to Slave Offset correction • Propagation delay of each link Master TC Slave

  37. PTP v2 configuration

  38. CLI Confidential

  39. Command Line Interface • Support serial console and telnet console • Help instruction and easy lookup • Type “?” for help • Type TAB for command hints Confidential

  40. CLI Mode • Default: Menu mode Menu mode -> CLI mode CLI mode -> Menu mode

  41. CLI configuration • CLI entry

  42. Configure Terminal

  43. Show Configuration

  44. Network Traffic Control Confidential

  45. Loop Protection Looping • Default enabled • Port blocked • Single port loopback • Two port loop • Fault-> RED • Not available on Ring/Chain & RSTP port Confidential

  46. Traffic Limiting • Port Disabled mode Port disabled period Ingress packet per second

  47. Traffic Limiting • Ingress/Egress limiting Bandwidth %

  48. EDR-G902 Click to add subtitle Confidential

  49. EDR-G902 • Hardware Specification • WAN: 1 Gigabit RJ45/SFP combo port • LAN: 1 Gigabit RJ45 copper • Redundant power input • Wide temperature support • Software Specification • Bridge mode • VRRP • Router, VPN, Firewall, NAT… Confidential

  50. EDR-G902 Redundant power input 1x DI & 1 DO WAN port: Copper/SFP Combo port LAN port: Copper port Confidential
