Configuration Management
Showing and Saving the Current Config
The configuration of the Cisco Nexus 3550-F Fusion (formerly ExaLINK Fusion) is described by a running-config
. The 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 running-config
to the startup-config
, use the copy
command:
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 time.
Erasing Configurations
The 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
-
all
will reset the running-config to the factory default settings, potentially rendering the device inaccessible from the current connection. -
management
will 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-plane
will reset all port configs and delete all patch/tap/mux/switch and mirror objects. -
module
will reset any internal module specific settings, for example the selection betweenmux
orswitch
firmware, or anycustom
module settings applied.
NoteErasing the 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
The 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 admin@192.168.220.10
admin@192.168.220.10's password:
Connected to 192.168.220.10.
sftp> get *.conf
