To configured Cisco devices you must working In cli. Cli isn't so friendly as windows interface, but offers some useful thing to move more easily in command line interface .
First command which help us is INCLUDE or BEGIN
INCLUDE
Example:
When we want display Only this interface which is In vlan 31 we can use „#show interfaces status” but then it will display all interfaces.

But when we use #show interfaces status | include 31 it will show as only interfaces In vlan 31
Include works like grep linux command and display only this line what have specifics strings
Begin
"Begin" command starts displaying configuration, starting from specific string:
For example: we want see Interface configuration where is some specific description like some server name. We don’t need display all configuration and search by own this interface we can use ” show run | begin server1 „
Because interface configuration always starts at description this command shows to as all configuration of this specifics interface
Another command is „do”
If we want set the interface to some vlan but we are In interface mode :
„switch(config-if)#” and we forgot what was the number the vlan what we want set. We use then „do show vlan „
Thanks to this command we can use all command from privilege mode in config mode isn’t beautiful :)
Very useful command "range"
What to do if we want set port security to all 48 interfaces . We don’t enter to config mode each one interface. We used range !!!
And now we can set port security in all interface in one time.
The last command is "reload in"
When you configured router remotely you can always do some mistakes special when you added some new access-list and you cut off access to router. In this case you can call to someone but if there is no body ? In this case you can use command "reload in 30" to order the router to reboot in 30 minutes then startup configuration will return and you can again access to router. To cancel the counter using "reload cancel".
You must remember to always create description on interface it will be very useful in some case of emergency and to normal working in cisco devices.
This command you can used in many situation -use your invention! :)
