Command Modes

Command History

Release	Modification
NX-OS 4.1(3)	This command was introduced.

Usage Guidelines

The port guard feature is used in the environments where the system and application does not adapt quickly and efficiently to a port going down and back up or to a port rapidly cycling up and down which can happen in some failure modes. For example, if the port is going up and down once a second, and the system takes five seconds to stabilize after the port goes down, this situation might cause a more severe failure in the fabric.

The port guard feature gives the SAN administrator the ability to prevent this issue from occuring in environments that are vulnerable to these problems. The port can be configured to stay down after the first failure, or after a specified number of failures in a specified time period. This allows the SAN administartaion to intervene and control the recovery and avoiding any problems caused by the cycling.

Examples

The following example shows how to configure the port as down when the link flaps once:

Switch# configure terminal

Switch (config)# interface fc1/1

Switch (config-if)# errdisable detect cause link-down

The following example shows how to configure the port as down when the link flaps 5 times in 30 seconds:

Switch# configure terminal

Switch (config)# interface fc1/1

Switch (config-if)# errdisable detect cause link-down num-times 5 duration 30

The following example shows how to remove the port guard feature on the interface:

Switch# config t

Switch (config)# interface fc1/1

Switch (config-if)# no errdisable detect cause link-down

NX-OS 4.1(2)	This command was introduced.

Usage Guidelines

This event specification monitors whenever there is insertion or removal of the following components: fan, module, and power supply. Embedded Event Manager takes an action based on the actions configured on the applet.

Examples

This example shows how to configure the Online Insertion Removal event specification:

switch# configure terminal

switch(config)# event manager applet moduleOir

switch(config-applet)# event oir module anyoir

switch(config-applet)# action 1.0 syslog priority informational msg a module was oir-ed

switch(config-applet)# end

event poweroverbudget

The power over-budget policy gets triggered when the available power capacity drops below zero and the device is no longer able to keep the previously powered-up modules in the powered-up state. The default action is to print a syslog to notify the user of the occurrence of power over budget. To change the power over budget behavior, use the event poweroverbudget command. You must override the default system policy __pfm_power_over_budget with a new policy to do this. To remove the power over-budget event specification, use the no form of the command.

Command Modes

EEM applet configuration (config-applet).

Command History

Release	Modification
NX-OS 4.1(2)	This command was introduced.

Usage Guidelines

An Embedded Event Manager event is triggered when one of the fields specified by an SNMP object ID crosses a defined threshold. If multiple conditions exist, the SNMP event is triggered when all the conditions are met.

Exit criteria are optional. If exit criteria are not specified, event monitoring will be re-enabled immediately. If exit criteria are specified on the basis of values or time periods, the event monitoring is not re-enabled until the criteria are met.

When the entry-op keyword is used and there is a match, an event is triggered and event monitoring is disabled until the exit criteria are met.

When the exit-op keyword is used and there is a match, an event is triggered and event monitoring is re-enabled.

The entry-type keyword triggers one of the following actions:

If the value keyword is specified, the entry-value is an actual value and an SNMP event is raised whenever the absolute value occurs.
If the increment keyword is specified, the entry-value is an increment and an SNMP event is raised whenever the incremental value is reached.
If the rate keyword is specified, the entry-value is a rate of change and an SNMP event is raised whenever the rate of change value is reached.

When the optional exit-type keyword is used, the following conditions occur:

If the value keyword is specified, the exit value is an actual value and the event monitoring is re-enabled whenever the absolute value occurs. This is the default.
If the increment keyword is specified, the exit value is an increment and the event monitoring is re-enabled whenever the incremental value is reached.
If the rate keyword is specified, the exit value is a rate of change and the event monitoring is re-enabled whenever the rate of change value is reached.

Examples

The following example shows how to monitor the CPU free memory OID and log a corresponding syslog:

switch# configure terminal

switch(config)# event manager applet snmp-applet

switch(config-applet)# event snmp oid 1.3.6.1.4.1.9.9.109.1.1.1.1.13.1 get-type exact entry-op lt entry-val 100000 poll-interval 60

switch(config-applet)# action 1.0 syslog priority warnings msg free memory fell below 100 Mb

switch#(config-applet)# end

event syslog

To specify event criteria for an Embeded Event Manager applet that is run by matching syslog messages, use the event syslog command in the applet configuration mode. To remove the syslog message event criteria, use the no form of the command.

Syntax Description

occurs count	(Optional) Specifies the number of occurrences of the matched syslog messages to count before triggering the policy event. count range is platform specific.
period interval	(Optional) Specifies the maximum time within which the timestamps of the triggering messages must fall. interval range is platform specific.
priority	(Optional) Specifies the number or name of the desired priority level at which syslog messages are matched. Messages at or numerically lower than the specified level are matched. The parameter for priority must be one of the following: • 0 \| emergencies — Specifies syslog messages of emergency level (the system is unusable). • 1 \| alerts — Specifies syslog messages of alert level (immediate action is needed). • 2 \| critical — Specifies syslog messages of critical level (critical conditions). • 3 \| errors — Specifies syslog messages of error level (error conditions). • 4 \| warnings — Specifies syslog messages of warning level (warning conditions). • 5 \| notifications — Specifies syslog messages of notification level (normal but significant conditions). • 6 \| informational — Specifies syslog messages of informational level (informational messages). • 7 \| debugging — Specifies syslog messages of debugging level (debugging messages).
pattern expression	Specifies a regular expression to match against syslog messages. The pattern must be quoted with " " quotes. expression maximum size is 256 characters.

Defaults

If the occurs parameter is not specified, the default value of 1 is used.

If the period parameter is not specified, the default value of 0 is used.

If the priority parameter is not specified, the default value of informational is used.

Command Modes

EEM applet configuration (config-applet).

Command History

Release	Modification
5.2(1)	This command was introduced.

Usage Guidelines

The syslog and Embedded Event Manager client processes run on each supervisor module in a system. Therefore, in dual supervisor systems, an event syslog command will be matched on both the active and standby supervisors. Both Embedded Event Manager clients will notify the Embedded Event Manager master process on the active supervisor causing the applet to be triggered twice. Be sure to take this potential double triggering in to account in the applet.

This command does not require a license.

Examples

This example shows how to configure an applet to trigger after 10 "authentication failed" syslog events:

switch# configure terminal

switch(config)# event manager applet auth-fails-applet

switch(config-applet)# event syslog occurs 10 pattern "authentication failed"

Configuration accepted successfully

This example shows how to configure an applet to tag module power up and standby online syslog events:

switch# configure terminal

switch(config)# event manager applet mod-event-applet

switch(config-applet)# event syslog tag moduleEvent pattern "(powered up|is standby)"

Configuration accepted successfully
