Log messages with the selected severity level and all log messages of greater severity
are logged. For example, if you select Warning, the logged messages include
Warning, Error, Critical, Alert, and Emergency. The default severity level is Error (3).
The severity can be one of the following levels:
• Emergency: Level 0, the highest warning level. If the device is down or not
functioning properly, an emergency log is saved to the device.
• Alert: Level 1, the second-highest warning level. An alert log is saved if a serious
device malfunction occurs, such as all device features being down.
• Critical: Level 2, the third-highest warning level. A critical log is saved if a critical
device malfunction occurs, for example, two device ports are not functioning,
while the rest of the device ports remain functional.
• Error: Level 3, a device error occurred, such as a port being offline.
• Warning: Level 4, the lowest level of a device warning.
• Notice: Level 5, provides the network administrators with device information.
This is the default setting.
• Informational: Level 6, provides device information.
• Debug: Level 7, provides detailed information about the log.
NOTE: A log records messages equal to or above a configured severity
threshold.

Port mirroring
Port mirroring lets you select the network traffic of specific switch ports for analysis by
a network analyzer. For each port mirroring configuration (the switch supports up to
four), you can select many switch ports as source ports but only a single switch port as
the destination port. For each port mirroring configuration, you can configure how traffic
is mirrored on a source port by selecting packets that are received, transmitted, or both.
You can also apply an IP ACL or MAC ACL to filter the traffic that is being mirrored.
A packet that is copied to the destination port is in the same format as the original
packet. This means that if the mirror is copying a received packet, the copied packet is
VLAN-tagged or untagged as it was received on the source port. If the mirror is copying
