Muchas veces de las que hacemos un "show running-config" o lo que es más a menudo "sh run" no queremos ver todo si no un parte de la configuración, para ello hay algunos atajos muy útiles que no siempre se recuerdan:

• show run interface:

  router# sh run int fa0/0
  Building configuration...
  Current configuration : 93 bytes
  !
  interface FastEthernet0/0
  ip address 10.1.2.1 255.255.255.0
  duplex auto
  speed auto
  end
  

• show run | section:

  router#sh run | section interface
  interface FastEthernet0/0
  ip address 10.1.2.1 255.255.255.0
  duplex auto
  speed auto
  interface FastEthernet1/0
  ip address 192.168.4.1 255.255.255.0
  duplex auto
  speed auto
  

• show run | begin :

  router#sh run | begin interface
  interface FastEthernet0/0
  ip address 10.1.2.1 255.255.255.0
  duplex auto
  speed auto
  !
  interface FastEthernet1/0
  ip address 192.168.4.1 255.255.255.0
  duplex auto
  speed auto
  !
  ip http server
  no ip http secure-server
  ip classless
  !
  control-plane
  !
  !
  

• show run | include:

  router# sh run interface f0/0 | include ip
  ip address 10.1.1.1 255.255.255.0
  

• show ip interface brief:

  router#sh ip interface brief
  Interface IP-Address OK? Method Status Protocol
  FastEthernet0/0 10.1.1.1 YES manual up up
  FastEthernet1/0 192.168.1.1 YES manual up up
  

• Mientras se está haciendo un "sh run" se puede usar el carácter / para hacer una búsqueda específica:

  router#sh run
  Building configuration...
  Current configuration : 663 bytes
  !
  version 12.3
  service timestamps debug datetime msec
  service timestamps log datetime msec
  no service password-encryption
  !
  hostname blog_demo
  !
  boot-start-marker
  boot-end-marker
  !
  !
  memory-size iomem 5
  no aaa new-model
  ip subnet-zero
  !
  !
  !
  !
  ip cef
  ip ips po max-events 100
  /192.168
  filtering...
  ip address 192.168.4.1 255.255.255.0
  duplex auto
  speed auto
  !
  ip http server
