 Huawei AR routers have easy and effective memory usage monitoring tool. When memory usage exceeds configured threshold, the system logs the event and generates an alarm. When memory usage falls within the alarm threshold, the system generates a clear alarm.

By default memory usage threshold is set to 90% when the memory capacity on the interface board is lower than or equal to 128MB, and 95% when the memory capacity is higher that 128MB. Memory usage threshold can be easly changed using command:

[labnario]set memory-usage threshold 75

What we want to do is to configure 802.1q trunk between labnario1 router and labnarioSW1 switch, so that hosts from VLAN 100 will be able to ping the router’s interface.

Let’s look at the simple topology:

First we want to configure labnario1 router. To configure Ge0/0/1 interface to operate as a 802.1q trunk, we need to configure it as follows:

<labnario1>system-view
[labnario1]
[labnario1]interface GigabitEthernet 0/0/1
[labnario1-GigabitEthernet0/0/1]portswitch
[labnario1-GigabitEthernet0/0/1]port link-type trunk
