System Log
If you enable the System Log, the messages display on the
Alerts tab; see “System Log” on page 29.
System Log This option enables the registration routine
of system log (syslog) messages. By default it is disabled.
• Remote Log Enables the syslog remote sending
function. System log messages are sent to a remote
server, which is specified in the following fields:
- Remote Log IP Address The host IP address that
receives syslog messages. Properly configure the
remote host to receive syslog protocol messages.
- Remote Log Port The TCP/IP port that receives syslog
messages. 514 is the default port for the commonly
used system message logging utilities.
Every logged message contains at least a system time and
host name. Usually a specific service name that generates
the system event is also specified within the message.
Messages from different services have different contexts
and different levels of detail. Usually error, warning, or
informational system service messages are reported;
however, more detailed debug level messages can also
be reported. The more detailed the system messages
reported, the greater the volume of log messages
generated.
NTP Client
Network Time Protocol (NTP) is a protocol for
synchronizing the clocks of computer systems over
packet-switched, variable-latency data networks. You can
use it to set the system time on the device. If the System
Log option is enabled, then the system time is reported
next to every log entry that registers a system event.
NTP Client If enabled, the device obtains the system time
from a time server on the Internet.
• NTP Server Specify the IP address or domain name of
the NTP server. The default is 0.ubnt.pool.ntp.org.
Spanning Tree Protocol
For optimal performance, there should be a single
active path between two networking devices in an
Ethernet network. Spanning Tree Protocol (STP) provides
redundant paths and prevents network loops that can
create excessive traffic and slow down performance. STP
calculates the best path for network traffic; if the best path
fails, STP recalculates and finds the next best path.
Status Enabled by default, STP provides redundancy
without network loops.
Version Select the version of STP to use. STP and Rapid
STP (RSTP) display the following states: Blocking, Learning,
and Forwarding. RSTP is recommended because ports
can more quickly progress to the forwarding state. When
STP is selected, the TOUGHSwitch sends STP packets. The
default is RSTP.
Max Age Specify how long the TOUGHSwitch saves
a configuration message received on a port. If the
TOUGHSwitch does not hear any new configuration
messages after the Max Age time interval, then the
TOUGHSwitch adapts and starts to reconfigure. The
default is 20 seconds.
Hello Time Specify the time interval between
configuration messages transmitted by the TOUGHSwitch
to other switches. The default is 2 seconds.
Forward Delay Specify how long the listening and
learning states last before the TOUGHSwitch forwards
traffic. The default is 15 seconds.
Priority STP uses priority values to select a switch as the
root switch of the spanning tree. Specify the Priority value
of the TOUGHSwitch. The default is 32768.
Jumbo Frames
The Maximum Transmission Unit (MTU) is the maximum
packet size (in bytes) that a network interface can transmit.
A jumbo frame is a frame that is larger than the standard
Ethernet frame with an MTU of 1500. Jumbo frames are
typically used for Gigabit Ethernet connections.
Jumbo Frames By default, this option is disabled; the
TOUGHSwitch does not handle jumbo frames and drops
them. If you enable this option, the TOUGHSwitch handles
jumbo frames and forwards them. The maximum MTU of
the TOUGHSwitch PoE is 9216, and the maximum MTU of
the TOUGHSwitch PoE PRO is 9720.
