On a Cisco IOS Router you have the comman show running-config this will show you the entire configuration which are currently is configured. How ever beside the show running-config you have some extra commands shown here below:
sh run | ? append Append redirected output to URL (URLs supporting append operation only) begin Begin with the line that matches count Count number of lines which match regexp exclude Exclude lines that match format Format the output using the specified spec file include Include lines that match redirect Redirect output to URL section Filter a section of output tee Copy output to URL
With these options you can see parts of the configuration without searching through the whole configuration.
I saw recently other users using other commands to see what was configured in the configuration. Probably you would know the command options already and if now take advantage of it.
You can use the show running-config command in combination with a configured part of the configuration. Example:
show running-config interface G 0/0 Building configuration... Current configuration : 184 bytes ! interface GigabitEthernet0/0 description Gigabit0 no ip address load-interval 30 duplex full speed 100 pppoe enable group global pppoe-client dial-pool-number 10 end
As you see the configuration command will only show you the configuration of that part of you interface configuration.
There are more commands which are available before you are using the show running-config |
sh run ? all Configuration with defaults brief configuration without certificate data class-map Show class-map information control-plane Show Control-Plane information flow Global Flow configuration subcommands full full configuration interface Show interface configuration linenum Display line numbers in output map-class Show map class information partition Configuration corresponding a partition policy-map Show policy-map information view View options vlan Show L2 VLAN information vrf Show VRF aware configuration | Output modifiers <cr>
Most of the time I won’t use it but after today I think different.
