show vlan brief
show interface trunk
show interface switchport
show vtp status
show spanning-tree vlan


show frame map
show frame pvc


show ip route ospf
show ip ospf database
show ip ospf neighbor
show ip ospf
show ip ospf interface
show ip ospf interface brief


show ip eigrp neighbor
show ip eigrp topology
show ip route eigrp
show ip protocol

RIP version 2

show ip route rip
clear ip route *
debug ip rip


show ip bgp summary
show ip bgp
show ip bgp neighbor x.x.x.x advertised-routes
show ip bgp regex
show ip bgp rib-failure
show ip route bgp

IP Multicast

debug ip mpacket
debug ip pim
show ip pim neighbor
show ip pim interface
show ip pim rp map
show ip mroute count

    thanks for this list. I hate to get of subject but I need help in trying to determine the requirements to setup a 99.999% network? Do you know of any good references?

    It might be nice to see the smallest abbreviated versions of those commands. A keystroke saved is a keystroke earned. Example:
    “sh ip int b” for “show ip interface brief”.

  6. Michael – it looks like this Cisco Press book provides a nice overview of what you need for a Cisco-biased network.
