IGMP Snooping Multicast Service Configure ZTE OLT

IGMP Snooping Multicast Service Configure ZTE OLT

[boxads]

Today i will discuss how to IGMP Snooping Multicast Service Configure in ZTE OLT.

Prerequisites:

• Make sure that network device works normally.
• Make sure that multicast source exits in the uplink network.
• Make sure that GPON card works normally.
• Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Background Information:

When an ONU is registered on the ZXA10 C220, the OLT creates a multicast service connection automatically.

• Bridge_0/1
• GEM port ID: 1021
• Uplink_0/1/255

On the ONU, the multicast service connection transmits only multicast service packets and the multicast protocol packets are transmitted in the unicast service connection.

The F621 supports one MVLAN and 32 multicast groups.

IGMP snooping multicast service configuration data:

Note: The ZXA10 C220 supports 8 service priorities (0 – 7), where 0 is the lowest priority and 7 is the highest priority.

It is recommended to configure the service priority as follows:

• Priority of data service: 1
• Priority of IPTV service: 5
• Priority of VoIP service: 7
• Priority of CES service: 7

IGMP snooping multicast service configuration flowchart:

To configure the IGMP snooping multicast service, perform the following steps:

1. Register ONU.

i. Query unconfigured ONU on the GPON-OLT port.
ZXAN#show gpon onu uncfg gpon-olt_0/5/1
OnuIndex                   Sn                                  State
———————————————————

gpon-onu_0/5/1:1    ZTE_06120664          unknown

ii. Enter the global configuration mode.
ZXAN#configure terminal
Enter configuration commands, one per line. End with CTRL/Z.
ZXAN(config)#

iii. Enter the GPON-OLT interface configuration mode.
ZXAN(config)#interface gpon-olt_0/5/1
ZXAN(config-if)#

iv. Register ONU.
ZXAN(config-if)#register 1 type ZTE-F621 ZTE_06120664 state ready

v. Query ONU state.
ZXAN(config-if)#show gpon onu state gpon-olt_0/5/1
OnuIndex                  Admin State Omcc State O7 State        Phase State
————————————————————————-

gpon-onu_0/5/1:1  enable             enable           operation     working
ZXAN(config-if)#exit
ZXAN(config)#

2. Configure bandwidth profile.

i. Enter the GPON configuration mode.

3. Configure T-CONT and GEM port.

• T-CONT (Transmission Container) is the minimum unit of upstream bandwidth scheduling which is identified by Alloc ID.
• GEM (GPON Encapsulation Method) port is the minimum unit of downstream traffic which is identified by port ID.

i. Enter the GPON-ONU interface configuration mode
ZXAN(config)#interface gpon-onu_0/5/1:1
ZXAN(config-if)#

ZXAN(config-if)#switchport vlan 21 tag vport 1
ZXAN(config-if)#switchport vlan 22 tag vport 2
ZXAN(config-if)#exit
ZXAN(config)#

Note: When a port is added to a VLAN, the VLAN is added automatically.

5. Configure VLAN uplink port.

i. Enter the OLT uplink port configuration mode.
ZXAN(config)#interface gei_0/14/1

ii. Configure uplink port mode to hybrid.
ZXAN(config-if)#switchport mode hybrid

iii. Add uplink port to MVLAN in tag mode.

6. Configure ONU unicast service connection.

i. Enter the ONU remote management mode.
ZXAN(config)#pon-onu-mng gpon-onu_0/5/1:1
ZXAN(gpon-onu-mng)#

ZXAN(gpon-onu-mng)#mac-filter uplink uplink_0/1/255 0100.5e01.0103 forward
ZXAN(gpon-onu-mng)#exit
ZXAN(config)#

Note: According to IANA, mutlicast MAC addresses are 01:00:5E:00:00:00 – 01:00:5E:7F:FF:FF. As a 28–bit IP address is mapped to a 23–bit MAC address, 32 multicast IP addresses are mapped to one MAC address.

8. Configure IGMP global parameters.

Enable global IGMP and IGMP span-VLAN functions.
ZXAN(config)#igmp enable
ZXAN(config)#igmp span-vlan enable

This instance uses the default values for other IGMP global parameters. To configure IGMP global parameters, refer to Configuring IGMP Global Parameters.

Note: When user VLAN is different from MVLAN, the span-VLAN function must be enabled.

9. Configure IGMP port parameters.

ZXAN(config)#iptv package name pkg1
ZXAN(config)#iptv package pkg1 channel channel1 preview
ZXAN(config)#iptv package pkg1 channel channel2 watch
ZXAN(config)#iptv package pkg1 channel channel3 deny

– When CAC is enabled, the user can watch channels only when he has purchased the IPTV package.
– When CAC is disabled, the user can watch channels when he is in the MVLAN receiving port
– CAC is disabled by default.

ii. Configure user port right.
ZXAN(config)#interface gpon-onu_0/5/1:1
ZXAN(config-if)#iptv package pkg1 vport 1

13. Save configuration data.

ZXAN(config-if)#end
ZXAN#write
