某局点S5560X-EI配置灵活QinQ报错的处理经验案例

客户在5560X-EI上配置灵活QinQ功能

配置灵活QinQ功能的时候设备报错：

%Feb 26 12:24:24:179 2013 leaf1 QOS/4/QOS_POLICY_APPLYIF_CBFAIL: Failed to apply classifier-behavior qinq in policy qinq to the inbound direction of interface GigabitEthernet1/0/2. The operation is not supported. 

主要配置如下

traffic classifier qinq operator and

 if-match service-vlan-id 5

# 

traffic behavior qinq

 nest top-most vlan 10 

#

qos policy qinq classifier

 qinq behavior qinq 

#

interface GigabitEthernet1/0/2

 port link-mode bridge

 port link-type hybrid

 port hybrid vlan 1 10 untagged 

 qos apply policy qinq inbound 

1、检测配置，和官网的案例基本一致

# 定义类test的匹配规则为：匹配从GigabitEthernet1/0/1收到的VLAN ID值为5的报文。

<PE1> system-view

[PE1] traffic classifier test

[PE1-classifier-test] if-match service-vlan-id 5

[PE1-classifier-test] quit

# 在流行为test上配置如下动作：添加VLAN ID为100的外层VLAN Tag。

[PE1] traffic behavior test

[PE1-behavior-test] nest top-most vlan 100

[PE1-behavior-test] quit

# 在策略test中为类test指定采用流行为test。

[PE1] qos policy test

[PE1-qospolicy-test] classifier test behavior test

[PE1-qospolicy-test] quit

# 配置下行端口GigabitEthernet1/0/1为Hybrid端口且允许VLAN 100的报文不携带VLAN Tag通过。

[PE1] interface gigabitethernet 1/0/1

[PE1-GigabitEthernet1/0/1] port link-type hybrid

[PE1-GigabitEthernet1/0/1] port hybrid vlan 100 untagged

# 在下行端口GigabitEthernet1/0/1的入方向上应用上行策略test。

[PE1-GigabitEthernet1/0/1] qos apply policy test inbound

[PE1-GigabitEthernet1/0/1] quit

2、经核实，确认5560X-EI等Marvell芯片的交换机不支持匹配service-vlan-id，应该使用customer-vlan-id代替，客户修改配置后问题解决

[leaf1-GigabitEthernet1/0/2]undo qos apply policy qinq inbound

[leaf1-GigabitEthernet1/0/2]qu

[leaf1]traffic classifier qinq

[leaf1-classifier-qinq]undo if-match service-vlan-id 5

[leaf1-classifier-qinq]if-match customer-vlan-id 5

[leaf1-classifier-qinq]qu

[leaf1]int g1/0/2

[leaf1-GigabitEthernet1/0/2]qos apply policy qinq inbound

5560X-EI等Marvell芯片交换机不支持匹配svlan，应该使用cvlan匹配报文内层标签，

# 定义类test的匹配规则为：匹配从GigabitEthernet1/0/1收到的VLAN ID值为5的报文。

<PE1> system-view

[PE1] traffic classifier test

[PE1-classifier-test] if-match customer-vlan-id 5

[PE1-classifier-test] quit

# 在流行为test上配置如下动作：添加VLAN ID为100的外层VLAN Tag。

[PE1] traffic behavior test

[PE1-behavior-test] nest top-most vlan 100

[PE1-behavior-test] quit

# 在策略test中为类test指定采用流行为test。

[PE1] qos policy test

[PE1-qospolicy-test] classifier test behavior test

[PE1-qospolicy-test] quit

# 配置下行端口GigabitEthernet1/0/1为Hybrid端口且允许VLAN 100的报文不携带VLAN Tag通过。

[PE1] interface gigabitethernet 1/0/1

[PE1-GigabitEthernet1/0/1] port link-type hybrid

[PE1-GigabitEthernet1/0/1] port hybrid vlan 100 untagged

# 在下行端口GigabitEthernet1/0/1的入方向上应用上行策略test。

[PE1-GigabitEthernet1/0/1] qos apply policy test inbound

[PE1-GigabitEthernet1/0/1] quit
