Example for Outputting Logs to a Log Host

Procedure

1. Enable the information center.

   <HUAWEI> system-view
   [HUAWEI] sysname SwitchA
   [SwitchA] info-center enable
   

2. Configure a channel and a rule for outputting logs to a log host.

   # Name a channel.

   [SwitchA] info-center channel 6 name loghost1
   [SwitchA] info-center channel 7 name loghost2
   

   # Configure a channel for outputting logs to a log host.

   [SwitchA] info-center loghost 10.1.1.1 channel loghost1
   [SwitchA] info-center loghost 10.1.1.2 channel loghost1
   [SwitchA] info-center loghost 10.2.1.1 channel loghost2
   [SwitchA] info-center loghost 10.2.1.2 channel loghost2
   

   # Configure a rule for outputting logs to a log host.

   [SwitchA] info-center source arp channel loghost1 log level notification
   [SwitchA] info-center source aaa channel loghost2 log level warning
   

3. Configure an IP address for the interface that sends log information.

   [SwitchA] vlan 100
   [SwitchA-vlan100] quit
   [SwitchA] interface gigabitethernet 0/0/1
   [SwitchA-GigabitEthernet0/0/1] port link-type hybrid
   [SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 100
   [SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 100
   [SwitchA-GigabitEthernet0/0/1] quit
   [SwitchA] interface vlanif100
   [SwitchA-Vlanif100] ip address 172.16.0.1 255.255.255.0
   [SwitchA-Vlanif100] return

4. Configure the log host on the server.

   The Switch can generate many logs, which may exceed the limited storage space of the Switch. To address this problem, configure a log server to store all the logs.

   The log host can run the Unix or Linux operating system or run third-party log software. For details about the configuration procedure, see the relevant documentation.

5. Verify the configuration.

   # View the configuration of the log host.

   <SwitchA> display info-center
   Information Center:enabled

           10.1.1.1, channel number 6, channel name loghost1,
