15 BASIC ADMINISTRATION PROTOCOLS
This chapter describes basic administration tasks including:
◆ Event Logging – Sets conditions for logging event messages to system
memory or flash memory, configures conditions for sending trap
messages to remote log servers, and configures trap reporting to
remote hosts using Simple Mail Transfer Protocol (SMTP).
◆ Link Layer Discovery Protocol (LLDP) – Configures advertisement of
basic information about the local switch, or discovery of information
about neighboring devices on the local broadcast domain.
◆ Power over Ethernet – Sets the priority and power budget for each port.
◆ Simple Network Management Protocol (SNMP) – Configures switch
management through SNMPv1, SNMPv2c or SNMPv3.
◆ Remote Monitoring (RMON) – Configures local collection of detailed
statistics or events which can be subsequently retrieved through SNMP.
◆ Switch Clustering – Configures centralized management by a single unit
over a group of switches connected to the same local network
CONFIGURING EVENT LOGGING
The switch allows you to control the logging of error messages, including
the type of events that are recorded in switch memory, logging to a remote
System Log (syslog) server, and displays a list of recent event messages.
SYSTEM LOG
CONFIGURATION
Use the Administration > Log > System (Configure Global) page to enable
or disable event logging, and specify which levels are logged to RAM or
flash memory.
Severe error messages that are logged to flash memory are permanently
stored in the switch to assist in troubleshooting network problems. Up to
4096 log entries can be stored in the flash memory, with the oldest entries
being overwritten first when the available log memory (256 kilobytes) has
been exceeded.
The System Logs page allows you to configure and limit system messages
that are logged to flash or RAM memory. The default is for event levels 0 to
3 to be logged to flash and levels 0 to 7 to be logged to RAM.
