Table 10 Configuration items
Item Description
Version
Set the user logging version: 1.0 or 3.0.
IMPORTANT:
Configure the user logging version according to the capacity of the log receiving
device. If the log receiving device does not support user logging of the specified
version, the device cannot resolve the logs received.
Log timestamps
Set the time zone for userlogs: UTC or localtime.
• UTC—Coordinated Universal Time, loosely defined as current date and time of
day in Greenwich, England.
• Localtime—Coordinated Universal Time (UTC) plus the UTC offset.
Source IP Address of
Packets
Set the source IP address of user logging packets.
After you specify the source IP address, when Device A sends user logs to Device B,
it uses the specified IP address instead of the actual egress address as the source IP
address of the packets. In this way, although Device A sends out packets to Device
B through different ports, Device B can judge whether the packets are sent from
Device A according to their source IP addresses. This function also simplifies ACL
and security policy configurations. If you specify the same source address as the
source or destination address in the rule command in ACL, the IP address variance
and the influence of interface status can be masked to filter user logging packets.
H3C recommends you to use the IP address of the loopback interface as the source
IP address of user logging packets.
