local4.info /var/log/Device/info.log
In this configuration, local4 is the name of the logging facility that the log host uses to
receive logs, and info is the informational level. The UNIX system records the log
information that has a severity level of at least informational to the file
/var/log/Device/info.log.
e. Display the process ID of syslogd, end the syslogd process, and then restart syslogd
using the –r option to make the new configuration take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
The device can output MAC address logs to the log host, which stores the logs to the specified
file.

# Enable MAC Information on interface GigabitEthernet 1/0/1 to enable GigabitEthernet 1/0/1 to
record MAC address change information when the interface performs either of the following
operations:
{ Learns a new MAC address.
{ Deletes an existing MAC address.
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] mac-address information enable added
[Device-GigabitEthernet1/0/1] mac-address information enable deleted
[Device-GigabitEthernet1/0/1] quit
# Set the MAC Information queue length to 100.
