Usage Guidelines

Usage Scenario

When the link type of an interface is QinQ or the VLAN mapping or VLAN stacking function is configured on the interface, the system checks IP packets so that the device cannot transparently transmit IP error packets. In addition, during Layer 2 forwarding, devices cannot transparently transmit packets with the same source and destination IP addresses. To enable the device to transparently transmit IP error packets, you can run the ip error-packet-check disable command to disable the IP packet checking function.

Precautions

When the IP packet checking function is disabled, the IP subnet-based VLAN assignment, policy-based VLAN assignment, and IPv6 over IPv4 tunnel functions do not take effect. Therefore, confirm your action before disabling this function.

Example

# Disable the IP packet checking function on the interface GE0/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] ip error-packet-check disable
