TIMESTAMP="2005-10-24-21.37.13"
mgmtport="mgmt 0"
Use the no cli var name command in configuration mode to remove user-defined CLI persistent
variables:
The following example removes a user-defined CLI persistent variable:
switch# config t
switch(config)# no cli var name mgmtport

System Defined Variables

Cisco MDS NX-OS supports one predefined variable: TIMESTAMP. This variable refers to the time of
execution of the command in the format YYYY-MM-DD-HH.MM.SS.
The TIMESTAMP variable name is case sensitive. All letters must be uppercase.
Note
The following example uses $(TIMESTAMP) when periodically gathering statistics into files using the
command scheduler:
switch# config t l
switch(config)# scheduler enable
switch(config)# scheduler logfile size 16
switch(config)# scheduler job name j1
switch(config-job)# show interface mgmt0 | include mgmt > file
switch(config-job)# copy volatile:file bootflash:file.$(TIMESTAMP)
switch(config-job)# end
switch(config)#
The following example uses $(TIMESTAMP) when redirecting show command output to a file:
switch# show running-config > rcfg.$(TIMESTAMP)
Preparing to copy....done
switch# dir volatile:
