Huawei AR530 Series - Using Ping to Monitor the Reachability of Layer 3 Eth-Trunk Member Interfaces

Procedure
l Run the display eth-trunk [ trunk-id [ interface interface-type interface-number |
verbose ] ] command to check the Eth-Trunk configuration.
l Run the display lacp statistics eth-trunk [ trunk-id [ interface interface-type interface-
number ] ] command to check the statistics about LACPDUs sent and received in LACP
mode.
l Run the display interface eth-trunk [ trunk-id ] command to check the Eth-Trunk status.
l Run the display trunkmembership eth-trunk trunk-id command to check information
about member interfaces of an Eth-Trunk.

2.7.3 Using Ping to Monitor the Reachability of Layer 3 Eth-Trunk
Member Interfaces
Context
Multiple physical interfaces can be bundled into an Eth-Trunk, and these physical interfaces are
Eth-Trunk member interfaces. Each member interface uses a specified transmission path. The
path-specific service parameters, such as delay, jitter, and packet loss ratio, are also different.
Therefore, you cannot determine which member interface is faulty when the quality of services
on an Eth-Trunk deteriorates. To resolve this problem, perform a ping test to detect each physical
link to help locate the faulty link.
NOTE
The ping test applies to scenarios where two devices are directly connected through an Eth-Trunk.
Pre-configuration Tasks
Before using ping to monitor the reachability of Layer 3 Eth-Trunk member interfaces, complete
the following task:
l Running the undo portswitch command to configure the Eth-Trunk to work in Layer 3
mode and configuring an IP address for the Layer 3 Eth-Trunk
NOTE
An Eth-Trunk works in Layer 2 mode by default.
Procedure
Step 1 Enable the receive end to monitor Layer 3 Eth-Trunk member interfaces.
1. Run:
system-view
The system view is displayed.
2. Run:
trunk member-port-inspect
The receive end is enabled to monitor Layer 3 Eth-Trunk member interfaces.
