switch(config)#

Places you in global configuration mode.

Step 2

logging logfile logfile-name severity-level [ size bytes ]

Example:

switch(config)# logging logfile my_log 6

Configures the name of the log file used to store system messages and the minimum severity level to log. You can optionally specify a maximum file size. The default severity level is 5 and the file size is 10485760. Severity levels are listed in Table 8-1 . The file size is from 4096 to 10485760 bytes.

Example:

switch(config)# logging event link-status default

Logs interface events.

• link-status —Logs all UP/DOWN and CHANGE messages.
• trunk-status —Logs all TRUNK status messages.
• enable —Specifies to enable logging to override the port level configuration.
• default —Specifies that the default logging configuration is used by interfaces not explicitly configured.

switch(config)#

Places you in global configuration mode.

Step 2

logging module [ severity-level ]

Example:

switch(config)# logging module 3

Enables module log messages that have the specified severity level or higher. Severity levels, which range from 0 to 7, are listed in Table 8-1 . If the severity level is not specified, the default of 5 is used.

no logging module [ severity-level ]

Example:

switch(config)# no logging module

Disables module log messages.

Step 3

show logging module

Example:

switch(config)# show logging module

(Optional) Displays the module logging configuration.

Step 4

logging level facility severity-level

Example:

switch(config)# logging level aaa 2

Enables logging messages from the specified facility that have the specified severity level or higher. The facilities are listed in the Cisco Nexus 7000 Series NX-OS System Management Command Reference . Severity levels, which range from 0 to 7, are listed in Table 8-1 . To apply the same severity level to all facilities, use the all facility. For defaults, see the show logging level command.

no logging level [ facility severity-level ]

Example:

switch(config)# no logging level aaa 3

Resets the logging severity level for the specified facility to its default level. If you do not specify a facility and severity level, the device resets all facilities to their default levels.

Step 5

show logging level [ facility ]

Example:

switch(config)# show logging level aaa

(Optional) Displays the logging level configuration and the system default level by facility. If you do not specify a facility, the device displays levels for all facilities.

Step 6

logging timestamp { microseconds | milliseconds | seconds }

Example:

switch(config)# logging timestamp milliseconds

Sets the logging time-stamp units. By default, the units are seconds.

Note This command applies to logs that are kept in the switch. It does not apply to the external logging server.

no logging timestamp { microseconds | milliseconds | seconds }

Example:

switch(config)# no logging timestamp milliseconds

Resets the logging time-stamp units to the default of seconds.

Note This command applies to logs that are kept in the switch. It does not apply to the external logging server.

Step 7

show logging timestamp

Example:

switch(config)# show logging timestamp

(Optional) Displays the logging time-stamp units configured.

Step 8

copy running-config startup-config

Example:

switch(config)# copy running-config startup-config

Step 2

logging server host [ severity-level [ use-vrf vrf-name ]]

Example 1:

switch(config)# logging server 192.0.2.253

Example 2:

switch(config)# logging server 2001::)db*::3 5 use-vrf red

Configures a syslog server at the specified hostname or IPv4 or IPv6 address. You can limit logging of messages to a particular VRF by using the use-vrf keyword. In Cisco NX-OS Release 4.2 or higher, the default VRF is default. Severity levels, which range from 0 to 7, are listed in Table 8-1 . The default outgoing facility is local7.

Example 1 forwards all messages on facility local 7.

Example 2 forwards messages with severity level 5 or lower for VRF red.

no logging server host

switch(config)# no logging server host

Removes the logging server for the specified host.

Step 3

Step 4

show logging server

Example:

switch(config)# show logging server

(Optional) Displays the syslog server configuration.

Step 5

copy running-config startup-config

Example:

switch(config)# copy running-config startup-config

(Optional) Copies the running configuration to the startup configuration.

Facility

Creator of the message, which can be auth, authpriv, cron, daemon, kern, lpr, mail, mark, news, syslog, user, local0 through local7, or an asterisk (*) for all. These facility designators allow you to control the destination of messages based on their origin.

Note Check your configuration before using a local facility.

Level

Minimum severity level at which messages are logged, which can be debug, info, notice, warning, err, crit, alert, emerg, or an asterisk (*) for all. You can use none to disable a facility.

Action

Destination for messages, which can be a filename, a hostname preceded by the at sign (@), a comma-separated list of users, or an asterisk (*) for all logged-in users.

Step 1

show logging last number-lines

Example:

switch# show logging last 40

Displays the last number of lines in the logging file. You can specify from 1 to 9999 for the last number of lines.

Step 2

show logging logfile [ start-time yyyy mmm dd hh:mm:ss ] [ end-time yyyy mmm dd hh:mm:ss ]

Example:

switch# show logging logfile start-time 2007 nov 1 15:10:0

Displays the messages in the log file that have a time stamp within the span entered. If you do not enter an end time, the current time is used. You enter three characters for the month time field, and digits for the year and day time fields.

Step 3

show logging nvram [ last number-lines ]

Example:

switch# show logging nvram last 10

Displays the messages in the NVRAM. To limit the number of lines displayed, you can enter the last number of lines to display. You can specify from 1 to 100 for the last number of lines.

Step 4
