Item Descri
p
tion
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.
HP recommends you to use the IP address of the loopback interface as the source IP
address of user logging packets.
Log Host
Configura
tion
Log Host 1
Set the IPv4/IPv6 addresses, port number, and the VPN instance (this option is
available only when you specify a log host with an IPv4 address) of the userlog log
host to encapsulate user logs in UDP packets and send them to the specified userlog
log host. The log host can analyze and display the user logs to remotely monitor the
device.
You can specify up to two different userlog log hosts.
IMPORTANT:
To avoid collision with the common UDP port numbers, use a UDP port
number in the range 1025 to 65535.
Support for the IPv6 log host depends on the device model. For more
information, see
Network Management Configuration Guide
.
Log Host 2
Output userlog to the
information center
Set to output user logs to the information center in the format of system information.
IMPORTANT:
With this function enabled, user logs will not be output to the specified userlog
log host.
Outputting user logs to the information center occupies the storage space of the
device. Output user logs to the information center when there are a small amount
of user logs.
212BDisplaying user logging statistics
If you select to send user logs in UDP packets to the specified userlog log host, you can view the related
statistics, including the total number of user logs sent to the log host, the total number of UDP packets, and
the total number of user logs stored on the device cache.
1. Select Log Report > Userlog from the navigation tree to enter the page as shown in 798HFigure 32.
2. Click the Statistics expansion button on the page to view the user logging statistics as shown
in
799HFigure 33.
