The switch chassis, fans, power supplies, line cards, and supervisors also provide LEDs that signal status and conditions that require attention. The Quick Start Guide for the individual switches provides information about their LEDs.
Arista switching platforms are designed to work reliably in common data center environments.
To ensure their reliable operation and to monitor or diagnose the switch's health, Arista provides a set of monitoring capabilities available through the CLI or SNMP entity MIBs to monitor and diagnose potential problems with the switching platform.
In modular systems, cards are shut down when their temperatures exceed the critical threshold. The switch is shut down if the temperature remains above the critical threshold for three minutes.
The switch operates normally when one fan is not operating. Non-functioning modules should only be removed from the switch if they are immediately replaced; adequate switch cooling requires the installation of all components, including a non-functional fan.
Two non-operational fans trigger an insufficient fan shutdown condition. Under normal operations, this condition initiates a switch power-down procedure.
Fans are accessible from the rear panel.
Power supply LED indicators are visible from the rear panel.
The switch can be configured to continue operating during temperature shutdown conditions. Ignoring a temperature shutdown condition is strongly discouraged because operating at high temperatures can damage the switch and void the warranty.
Temperature shutdown condition actions are specified by the environment overheat action command. The switch displays this warning when configured to ignore shutdown temperature conditions.
switch(config)# environment overheat action ignore
====================================================================
WARNING: Overriding the system shutdown behavior when the system
is overheating is unsupported and should only be done under
the direction of an Arista Networks engineer. You risk damaging
hardware by not shutting down the system in this situation, and doing
so without direction from Arista Networks can be grounds for voiding
your warranty. To re-enable the shutdown-on-overheat behavior, use
the 'environment overheat action shutdown' command.
====================================================================
switch(config)#The running-config contains the environment overheat action command when set to ignore. When the command is not in running-config, the switch shuts down when an overheating condition exists.
The following running-config file lists the environment overheat action command.
switch# show running-config
! Command: show running-config

endThe switch can be configured to ignore the insufficient fan shutdown condition. This is strongly discouraged because continued operation without sufficient cooling may lead to a critical temperature condition that can damage the switch and void the warranty.
Insufficient-fans shutdown override is configured by the environment insufficient-fans action command. The switch displays this warning when configured to ignore insufficient-fan conditions.
switch(config)# environment insufficient-fans action ignore
====================================================================
WARNING: Overriding the system shutdown behavior when the system
has insufficient fans inserted is unsupported and should only be done
under
the direction of an Arista Networks engineer. You risk damaging
hardware by not shutting down the system in this situation, and doing
so without direction from Arista Networks can be grounds for voiding
your warranty. To re-enable the shutdown-on-overheat behavior, use

====================================================================
switch(config)#The running-config contains the environment insufficient-fans action command when set to ignore. When running-config does not contain this command, the switch shuts down when it detects an insufficient-fans condition.
The switch can be configured to override the automatic fan speed. The switch normally controls the fan speed to maintain optimal operating temperatures. The fans can be configured to operate at a constant speed regardless of the switch temperature conditions.
Fan speed override is configured by the environment fan-speed command. The switch displays this warning when its control of fan speed is overridden.
switch(config)# environment fan-speed override 50
====================================================================
WARNING: Overriding the system fan speed is unsupported and should only
be done under the direction of an Arista Networks engineer.
You can risk damaging hardware by setting the fan speed too low
and doing so without direction from Arista Networks can be grounds
for voiding your warranty.
To set the fan speed back to automatic mode, use the
'environment fan-speed auto' command
====================================================================
switch(config)#The running-config contains the environment fan-speed override command if it is set to override. When running-config does not contain this command, the switch controls the fan speed.

Application1/2 Sw17The Precision Time Protocol (PTP) provides clock accuracy for networked devices, allowing clocks to be synchronized locally in increments of less than a microsecond. PTP uses a master-slave hierarchy similar to that used by NTP. The master clock provides the most precise time, and slave devices use its signal to synchronize their clocks.
The master clock sends a sync request, called an announce message by the IEEE 1588-2008 standard, at a regular interval. The slave clock responds with a time-stamped delay request message in order to measure and compensate for packet delays between the devices. The slave then receives a message from the master specifying the time of the delay message and allows the slave to calculate final values for clock synchronization. The time maintains synchronization by regularly exchanging PTP packets between master and slave.
To disable PTP globally on the switch, use the no or default forms of the ptp mode command.
Example
switch(config)# ptp mode boundary
switch(config)#To set the Time To Live (TTL) of PTP packets, use the ptp ttl command. TTL is the maximum number of hops that a PTP packet may make.
Example
switch(config)# ptp ttl 64
switch(config)#PTP Monitoring records PTP information, including the offset from the master, mean path delay, and skew values, which you view using a show command. PTP Syslog messages generate the metrics with threshold values configured on the switch when enabled. EOS enables PTP Monitoring by default.
Use the ptp monitor command to enable PTP monitoring on the device. The no form of the command disables PTP monitoring and clears all of the recorded PTP data.
Example
switch(config)# no ptp monitorThe offset is the difference in nanoseconds between master and slave time. Use the ptp monitor threshold offset-from-master command to specify the offset-from-master threshold in nanoseconds. EOS generates a Syslog message if the most recently calculated time offset from the PTP master occurs outside the configured range. The maximum offset threshold is one second. The no form of the command clears the threshold value and prevents further Syslog messages from generating for this parameter.
Example
switch(config)# ptp monitor threshold offset-from-master 500 Mean path delay is the mean time in nanoseconds PTP packets take to travel between master and slave. Use the ptp monitor threshold mean-path-delay command to specify the mean-path-delay threshold in nanoseconds. EOS generates a Syslog message if the value of the most recently calculated mean path delay becomes greater than or equal to this threshold. The maximum mean-path-delay threshold is one second. The no form of the command clears the threshold value and prevents further Syslog messages from generating for this parameter.
Example
switch(config)# ptp monitor threshold mean-path-delay 2000PTP skew is the clock frequency difference between master and slave. Use the ptp monitor threshold skew command to configure the value of the skew-threshold percentage. A Syslog message generates if the value of the most recently calculated skew does not fall within the range (1/(1+<threshold>), 1*(1+<threshold>)). Skew threshold percentage represents a double precision (16 digit) real number ranging from 0 (0%) to 10 (1000%). The no form of the command clears the threshold value and prevents further Syslog messages from generating for this parameter.
Example
switch(config)# ptp monitor threshold skew 5
