6.1. show running-config 

The virtual file 

running-config 

consists of a list of commands that, taken together, result in the 

currently running system configuration. 

 

This list of commands is usually not 100% identical to the list of commands a user has input 
to configure the device. That is because 

running-config 

is a textual representation of the 

system configuration which is stored in binary form in the RAM memory of the device. 

 

Since the effective device configuration is huge, 

running-config 

in the majority of cases only 

lists the delta between default settings and current settings. This significantly reduces the 
amount of output and greatly improves readability of the configuration, but it does require the 
reader to know what the default settings are. 

 

With 

show running-config all-defaults 

it is possible to include values that are at default. 

 

Example 12. Default vs. Non-default vs. All Defaults 

 

In this example if the speed and duplex settings of an Ethernet interface are at default values 
(auto-negotiation) then nothing will be output. If the user then changes the speed to be fixed 
at 1 Gbps then that value is now non-default and will be output. Duplex is also output, since it 
is forced to ‘full’ when the speed is fixed at 1 Gbps. 

 

Display current configuration for an interface. All settings are at default: 

 

myDevice#

 show running-config interface GigabitEthernet 1/4 

Building configuration

…

 

interface GigabitEthernet 1/4 
! 
end 

 

Now set the speed to 1Gbps and display the configuration again: myDevice# 

configure 

terminal

 

 

myDevice(config)# 

interface GigabitEthernet 1/4

 

myDevice(config-if)# 

speed 1000

 

myDevice(config-if)# 

end

 

 

 

myDevice# 

show running-config interface GigabitEthernet 1/4

 

Building configuration... 
interface GigabitEthernet 1/4 
speed 1000  
duplex full 
! 
end 

 

Include all default settings for that interface: 

 
myDevice

# show running-config interface GigabitEthernet 1/4 all-defaults 

Building configuration... 
interface GigabitEthernet 1/4 
 switchport voice vlan mode disable 
 no switchport voice vlan security 
 switchport voice vlan discovery-protocol oui 
 loop-protect 
 no loop-protect action 
 loop-protect tx-mode 
 switchport access vlan 1 
 switchport trunk native vlan 1 
 switchport hybrid native vlan 1 
 switchport trunk allowed vlan 1-4095 

 
... much output omitted for brevity ... 

 

Note how the output of 

show running-config 

can be restricted to a specific interface. There 

are several such filters, described below.
