26. VDSL Setting

27. VDSL Overview
•Very high bit rate Digital Subscriber Line
•Using twisted pair cable for data transmission
•Both Symmetric & Asymmetric Applications
•Downstream up to 100M, Upstream up to 45M (Async mode)
•Data can coexist with POTS service

28. VDSL Overview
FDM to support full duplex
• FDM (Frequency Division Multiplexing) : upstream and downstream use different
frequency, the transmission in both direction can take place in the same time. i.e: VDSL,
ADSL.
Most popular VDSL standard
• ANSI/ETSI Plan 998 : suit for asymmetrical

35. Benefits of VLAN
Increase performance
Flexible network segmentation
Simple management
Enhance network security
Reduce cost

36. VLAN Types
 Port-based VLAN, No Standard
- Can't across switch
 Tag-based VLAN, IEEE 802.1Q
- May across multiple switches
- Ethernet MTU 1522 bytes (Normal MTU=1518 bytes)

37. Tag-based VLAN Classification
Untagged frame
 A frame does not contain a tag header
Priority-tagged frame
 A frame with tag header carries priority but no VID (VID=0)
VLAN-tagged frame
 A frame with tag header carries both priority and VID.

38. 802.1Q VLAN
802.1Q Tag VLAN
 Each VLAN group has unique VID
 Each member of VLAN group can talk to each other
VLAN-aware
 The device can recognize and support VLAN-tagged frame
VLAN-unaware
 The device can't recognize VLAN-tagged frame

39. 802.1Q Process
Filtering
Database
Forwarding
Ingress Rule Process Egress Rule
Packet Packet
Receive Transmit
• Ingress Rule
– Classify the received frames belonging to a VLAN
• Forwarding Process
– Decide to filter or forward the frame
• Egress Rule
– Decide if the frames must be sent tagged or untagged

40. Ingress Rule
Tagged frame Tagged frame
VID VID
Untagged frame Ingress Rule Tagged frame
PVID
VLAN-aware switch can accept tagged and untagged frame
 For tagged frame
• Directly be transmitted between 802.1Q compliant device
 For untagged frame
• PVID is added onto this untagged frame as a tagged frame
• Then the tagged frame is transmitted
 PVID
• Default Port VLAN ID for incoming untagged frame

41. Forwarding Process
 Forwarding decision is based on the filtering database
• Filtering database contains two tables.
– MAC table and VLAN table
• First, check destination MAC address based on the MAC table
• Second, check the VLAN ID based on the VLAN table
 Egress port is the allowed outgoing member port of VLAN
 MAC Table  VLAN Table
Port MAC Address Aging Egress Egress frame

43. Static Register
 Static VLAN table contains four information:
• VID 、 Port 、 Ad Control 、 Egress Tag Control
Static Entry SVLAN table
VID1 : :Port 1(Fixed, tag)
VID1 Port 1(Fixed, tag) VID Port Ad Control Tag
VID2 : :Port 2(Forbidden)

44. Dynamic Register
 What is GVRP
• GARP VLAN Registration Protocol
• Dynamically create the VLAN between neighbor VLAN-aware
device
• VLAN is automatically registered and deregistered

45. 802.1Q Ingress Check
Use to limit the incoming traffic with the specific VLAN ID
Check 802.1Q VLAN table
The incoming traffic will be dropped if the port is not the
egress port of this VLAN ID
If the incoming traffic is untagged. The default VLAN ID of
the receiving port will be added first, then going to the
Ingress Check

53. VLAN Stacking Port Role
 Normal Port Role
For "regular" (non-VLAN stacking).
 Access Port Role
Adds the SP VLAN tag to all incoming frames
 Tunnel Port Role
Adds the SP VLAN tag to all incoming frames only when SP TPID is
different from incoming frame’s SP VLAN tag.

IGMP Snooping allows a switch to “listen to”

routers

88. Function of IGMP Snooping
•When a host joins a multicast group, it sends a
IGMP Report message with specified GDA it wants
to join.
• The IGMP snooping switch recognizes the IGMP
Report Message and add a GDA MAC Address of
associated port in the MAC Filtering Database.
• While multicast traffic is transmitted to the switch
next time, it will directly forward the traffic to the
ports associated with this GDA MAC address
regarding the Filtering Database.

96. INTRODUCTION
Reserved Multicast Group
224.0.0.0 – 224.0.0.255
Problems
• Unknown multicast frame with reserved multicast group
• Dropped by IGMP Unknown Multicast
Solution
UI review
• Web, CLI

97. Reserved Multicast Group
Range: D 224.0.0.0/24
RFC 3171: Multicast addresses in this range are
used for protocols control traffic that is not
forwarded off link.
• OSPF: 224.0.0.5
• NTP: 224.0.1.1
• RIP-v2m: 224.0.0.9
...

98. Issue in the past
OSPF multicast
When set to drop the Unknown multicast information
Port 1 Port 23
drop
When you need to use some protocol
with reserved multicast like OSPF,
those packets will be dropped since
they belong to the Unknown multicast.
Thus, OSPF will break here!

101. IGMP Snooping Vlan

102. IGMP Snooping Vlan Target
1.Allow a user’s VLAN to use multicast service
2.To prevent the MVlan from the user’s traffic
3.Under fixed mode, Mvlan is created
automatically and can not be modified.

103. IGMP Snooping Setting

104. MVR － Multicast VLAN
Registration

105. MVR Target
1.Allow a VLAN to share with multicast traffic
while each subscriber still in its VLAN
2.Separate multicast traffic VLAN and general
purpose VLAN for bandwidth and security issue
3.Designed for applications with wide-scaled
deployment multicast traffic across an Ethernet
ring-based service provider network

112. MVR Setup － CLI
VES-1616/24F-44(config)#
mvr <1-4094> ：
create a MVLAN
group <group-id> start-address <ip> end-address <ip> ：
set the range of the multicast group address in the vlan
mode <dynamic | compatible> ：
set the MVR operation mode
receiver-port <port-list> ：
set the RP of the MVLAN
source-port <port-list> ：
set the SP of the MVLAN
tagged <port-list> ：
the frames out of the port will be sent with 802.1Q tag

114. Troubleshooting

115. Firmware Upgrade by Console
1. Obtain the FW file, unzip it and save it in a folder on your
computer.
2. Connect your computer to the console port and use terminal
emulation software configured to the parameters we mentioned
before.
3. Turn off the VDSL and then on to restart it and begin a session
4. When you see the message “Press any key to enter Debug
Mode within 3 seconds”, press any key to enter debug mode.
5. Type atba5 after the Enter Debug Mode message (this changes
the console port speed to 115200 bps)
6. Change the configuration of your terminal emulation software to
use 115200 bps and reconnect to the VDSL
7. Type atur after the Enter Debug mode message

116. Restore configuration via console
9600/N/8/1
command ：
atba5
atur
atlc
atgo

117. Maintenance by WEB
Click Management, Maintenance in the navigation
panel

118. Firmware Upgrade by FTP
1. Use an FTP client to connect to the VDSL
C:>ftp <VDSL IP address>
2. Enter the User name
User: admin
3. Enter the management password (1234 by default)
Password: 1234
230 Logged in
4. Transfer the firmware file to the VDSL. The firmware file on your
computer that you want to put onto the VDSL is named XXX.bin.
The internal firmware file on the VDSL is named ras.
ftp>put firmware.bin ras
5. Quit FTP
ftp>bye
6. Wait for the update to finish. The VDSL restarts automatically.

119. Configuration Backup by FTP
1. Use an FTP client to connect to the VDSL
C:>ftp <VDSL IP address>
2. Enter the User name
User: admin
3. Enter the management password (1234 by default)
Password: 1234
230 Logged in
4. Transfer the configuration file from the VDSL. The
configuration file on your computer that you want to put onto
the VDSL is named XXX. The internal configuration file on
the VDSL is named config
ftp>get config XXX
5. Quit FTP
ftp>bye

120. Configuration Restore by FTP
1. Use an FTP client to connect to the VDSL
C:>ftp <VDSL IP address>
2. Enter the User name
User: admin
3. Enter the management password (1234 by default)
Password: 1234
230 Logged in
4. Transfer the configuration file to the VDSL. The configuration file on
your computer that you want to put onto the VDSL is named XXX.
The internal configuration file on the VDSL is named rom-0.
ftp>put XXX config
5. Quit FTP
ftp>bye
6. Wait for the update to finish. The VDSL restarts automatically.
