IGMP Proxy Multicast Service Configure ZTE OLT

[boxads]

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

Prerequisites:

  • Make sure that the network device works normally.
  • Make sure that multicast source exits in the uplink network.
  • Make sure that the 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.

ZTE GPON Protection Service Configuration

[boxads]

Today i will discuss how to configure ZTE GPON Protection Service. ZTE ZXA10 C220 provides GPON port protection by main and backup GPON ports switching mechanism. When the main GPON link is break, the backup takes over the GPON service automatically.

ZXA10 C220 supports three types GPON port switch mechanisms:

  • Force switch (high priority)
  • Alarm-triggered switch (middle priority)
  • Manual switch (low priority)

Configuring GPON Protection Service:

Prerequisites:

  • Make sure that network device works normally.
  • Make sure that VLAN is configured properly on uplink equipment.
  • Make sure that GPON data service is configured successfully.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Configuring ONU Service Connection in ZTE OLT

[boxads]

Today i will discuss how to Configuring ONU Service Connection in ZTE OLT.

Prerequisites:

  • Make sure that the network device works normally.
  • Make sure that the GPON card works normally.
  • Make sure that the GEM port is configured.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

ZXA10 C220 supports four types of service connection.

  • 802.1p
    The upstream packets arrived on the UNI of an ONU are mapped to a GEM port according to UNI and 802.1p priority.
  • UNI
    The upstream packets arrived on the UNI of an ONU are mapped to a GEM port according to UNI.
  • Bridge
    The upstream packets arrived on the UNI of an ONU are mapped to a GEM port according to VLAN ID. Meanwhile, the VLAN tag can be processed according VLAN filter rules. I and 802.1p priority.
  • 802.1p + bridge
    The upstream packets arrived on the UNI of an ONU are mapped to a GEM port according to VLAN ID and 802.1p
    priority. Meanwhile, the VLAN tag can be processed according VLAN filter rules.

describes the map of UNI, bridge, uplink interface, and GEM port.

MAP OF UNI BRIDGE, UPLINK INTERFACE, AND GEM PORT

Step-1. In the global configuration mode, use pon-onu-mng command to enter ONU remote management mode.
Step-2. Use interwork gemport command to configure the connection between GEM port to user side interface.

  • Use the interwork gemport bridge command to configure a bridge connection.
  • Use the interwork gemport dot1p command to configure 802.1p connection.
  • Use the interwork gemport dot1p-bridge command to configure 802.1p + bridge connection.
  • Use the interwork gemport uni command to configure UNI connection.

Step-3. For bridge or 802.1p + bridge connection, use the the bridge-port uni-bind command to bind UNI to bridge.

GEM Port Traffic Limit Configure in ZTE OLT

by

GEM Port Traffic Limit Configure in ZTE OLT

[boxads]

Prerequisites:

  • Make sure that the network device works normally.
  • Make sure that the GPON card works normally.
  • The bandwidth profile is configured.
  • The traffic profile is configured.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

GEM port is the minimum unit of downstream traffic which is identified by port ID. The downstream traffic is only effective when the schedule mode is based on ONU or GEM port.

To configure the GEM port traffic limit, performs the following steps:

Step-1. In the global configuration mode, use the gpon command to enter the GPON configuration mode.
Step-2. Use the schedule-mode command to configure the schedule mode.
Step-3. In the administrator mode, use the reset-card command to reset the GPON card.

Note: When a GPON card is reset, all configuration on the card are deleted.

Step-4. Use the interface command to enter GPON-ONU interface configuration mode.
Step-5. Use the qos-mgmt schedulemod command to enter the downstream scheduler mode.

The ZXA10 C220 supports the following downstream schedulemodes:

  • None: the schedule mode between four queues in a GEM port is SP/WRR.
  • SP: the schedule mode between GEM ports is SP.
  • WRR: the schedule mode between GEM ports is WRR.

Step-6. Use the tcont command to configure T-CONT.
Step-7. Use the gemport command to configure GEM port traffic limit.
