GPON 业务流量不通

1.排查配置

相关接口有没有Up, 线路模板绑定的对不对，Vlan有没有放通…

2.线路模板子接口和Tcont 配置是否成功

[H3C]dis pon diagnostic config-error interface Onu 6/0/20:1 

Onu6/0/20:1

Line Profile Name: line_profile_default Cfg Profile Name: config_profile_default

…

//如果有以下两个表项: TCONT_ADD_DBA   ONU_ADD_GEMPORT 

• 排查Olt带宽不足

[H3C-probe]dis pon diagnostic dba slot 6

Olt6/0/20      8500000     8372000       128000         0  //Free的量要大于Tcont的固定带宽+保证带宽

AllocId      Fix     Assure    Max

Onu6/0/20:1 1024  0 0      10000000

• Tcont必须被Gemrpot使用

• Onu能力集返回支持Tcont个数小于配置的Tcont个数；返回支持Gemport个数小于配置的Gemport个数

UniPofNum:0

…

• Onu通讯异常

重启Onu看是否恢复, 看其他配置是否正常

3.查询omci进程流模板信息

4. 接Onu进一步排查

替换onu进行测试

5.定位流量丢在哪里

流量链路：

Onu -- Pon芯片 -- 交换芯片

[H3C-Onu2/0/5:1]display uni 3 --查询Onu自己的UNI口统计

[H3C]display interface Onu 2/0/5:1 --查询的是PON芯片ONU的统计

XGSPON支持GPON不支持

[H3C]display interface Olt 2/0/5 --查询的是CTC OLT口的统计

XGSPON支持GPON需适配

具体故障处理步骤

1. 确认物理链路正常

1） 确认设备硬件运行正常。

2） 确认物理链路正常。

2. 检查mac表项学习

如果确认版本没有问题且配置已经下发，此时业务流量不通，请先确认设备是否已经学到对应表项。

示例：

# 查询P3500的mac学习表项。

P3500#brief-show mac-address

Agingtimer                    :300

Total MAC Count               :4

S-VID     MAC Address         Forward Port   Type           Virtual Port   Gem Port

---------------------------------------------------------------------------------------

31        01:00:94:00:00:01   Slot 1         Dynamic        1/1/1/1        289

31        02:02:94:00:00:02   TRUNK 1        Dynamic

4094      a0:c0:a8:d2:fe:02   Slot 1         Management

1         00:1c:82:0b:60:4b   Local          Management

4094      00:1c:82:0b:60:4b   Local          Management

TOTAL Count: 3

可以看到设备从1号槽位olt1接口关联的ont1接口的vport1端口接收到vlan tag为31的报文，学到的Mac地址为01:00:94:00:00:01；聚合口1接收的vlan tag为31的报文，学习到的Mac地址为02:02:94:00:00:02。

# 查询P3116的mac学习表项。

telnet@P3116(config-t)# show mac-address-table

Total Mac Addresses: 0

Interface Vlan  Type   LAG-Group  GroupID  MAC address        ONU-ID  GEM-Port  Cvid

---------------------------------------------------------------------------------------

telnet@P3116(config-t)#

3. 检查设备配置

如果发现mac表项都没有学习到，请检查如下的配置。

4. 检查链路聚合配置

如果配置了链路聚合，首先检查链路是否UP。

# 查询聚合口1信息。

P3500#configure l2 port show trunk 1

  Trunk group                :1

  Trunk name                 :1

  Port list                  :XGE 1,XGE 2

  Load balance scheme        :dstMAC

  Administrative Status      :UP

  Operational Status         :UP

  CfgSpeed                   :Auto

  CfgDup                     :Auto

  CfgFlow                    :Auto

  Actual speed               :10000M

  ActDup                     :Full

  ActFlow                    :Off

  Orient                     :Network

 telnet@P3116(config-t-if-lg-1)# show link-aggregation summary

telnet@P3116(config-t)# show interface link-aggregation 1 switchport

telnet@P3116(config-t)#

5. 检查gpon模板配置

# 模板id 为1的是默认配置。

GPFA-1-1(config-t)# show configuration running gpon-profile

enable

configure terminal

 gpon profile dba id 1 name newprof_dba_1 type4 max 1244160

 gpon profile flow id 1 1 name newprof_flow_1 uni-type veip uni-bitmap 0xff upmap-type vlanId 101 101 pri-bitmap 0xff vport 1

 gpon profile tcont-bind id 2 v-port 4 name tcontbind_1 vportsvc-id 1 tcont-id 1 tcontsvc-id 1

 gpon ont-authentication snonly

 exit all

GPFA-1-1(config-t)#

6. 检查ont接口配置

查看ont接口配置（Ont接口下涉及业务模板应用，uni端口vlan配置以及vport端口创建）

# 查询命令如下：

GPFA-1-1(config-t)# show configuration running interface-gpon-olt 1/<olt id> <ont id>

telnet@P3116(config-t)# show configuration running interface-gpon-olt 1/<olt id> <ont id>

查看不同olt口，不同ont接口，只需要修改olt id和ont id即可：

# 查看16口下 ont16的配置，以3500设备举例：

GPFA-1-1(config-if-gpon-ont-1/8/1)# show configuration running interface-gpon-olt 1/16 16

exit

GPFA-1-1(config-if-gpon-ont-1/8/1)#

7. 检查全局VLAN配置

# 查看全局VLAN配置，可以看到IS1/2口和聚合口1加入到vlan31，32，33，34。

P3500#brief-show vlan

vlan ingress check  : Enable

vlan user-isolation : Enable

# 查看全局VLAN配置：telnet@P3116(config-t)# show configuration running vlan。

P3116(config-t)# show configuration running vlan enable

configure terminal

  member ge1/16,ge2/1 tagged

exit

8. 检查vlan-translate配置

# 查看全局vlan-translate。

P3500#brief-show vlan-translate
