Showing and saving the current config
The configuration of the Cisco Nexus 3550-F Fusion (formerly ExaLINK Fusion) is described by a
running-config contains all of the settings that are currently in effect
on the device.
admin@N3550-F> configure show running-config hostname EXALINK-FUSION management address static 192.168.220.10 255.255.255.0 mux my_mux mode layer2 port upstream A2 port A1 timesync ptp 0 module X function mux telnet enable
To make the running-config persistent across reboots of the device, it
must be saved to the
startup-config. To save the
startup-config, use the
admin@N3550-F> configure copy running-config startup-config Saved running config to startup config
Any setting in the
startup-config will be applied to the device at boot
startup-config can be erased with the
erase startup-config command. This
command will revert the Fusion's power-up settings to the factory default settings.
Various elements of the
running-config can be erased, depending on how much of
the config you want to reset.
admin@N3550-F(config)> erase running-config Usage: erase startup-config erase running-config [all] [management] [module] [data-plane] Erase configuration files
allwill reset the running-config to the factory default settings, potentially rendering the device inaccessible from the current connection.
managementwill reset only those parts of the running-config related to the management of the device, not the high speed port config. For example, hostname management address, passwords, logging etc are all covered in this reset group. This could potentially render the device inaccessible from the current connection.
data-planewill reset all port configs and delete all patch/tap/mux/switch and mirror objects.
modulewill reset any internal module specific settings, for example the selection between
switchfirmware, or any
custommodule settings applied.
running-config takes place immediately after the command is executed. A warning
is given prior to executing any
erase running-config command that could
potentially disrupt your connection to the management interface.
Backing up the config
startup-config is stored within the Nexus 3550-F as a number of .conf
files. These can be retrieved from the device using sftp for backup purposes,
and put back onto the device if necessary.
$ sftp email@example.com firstname.lastname@example.org's password: Connected to 192.168.220.10. sftp> get *.conf
