INE's Cisco Mega Show Commands


I discovered these commands while watching a YouTube video on the CCIE R&S Lab and thought they would be of great use during the troubleshooting portion of the lab and in everyday troubleshooting.

   1.  Show IP Protocols Summary - shows all IP routing processes on the router

       router#show ip protocols summary
      Index Process Name
      0       connected
      1       static
      2       BGP 64000

   2. Show run | i access-list|class-map|policy-map|security|shutdown|control-plane - displays a key list of information from the router's configuration

       router#sho run | i access-list|class-map|policy-map|security|shutdown|control-plane
       class-map match-any Gold
       class-map match-any AF4
       class-map match-any AF3
       class-map match-any AF2
       policy-map BEST
        shutdown
       ip access-list extended MY-NETWORK-ACCESS
       access-list 101 permit ip host 192.168.0.20 any
       access-list 140 permit udp any any tos 5
       snmp-server system-shutdown

   3.  Ping 255.255.255.255 - pings all next-hop addresses on the router, great for checking connectivity

       router#ping 255.255.255.255
