● Which destination networks are in the routing table and the source of the routing entry.
To display the contents of the routing table or the route origin priority, use one of the following
commands:
■ show iproute—IPv4 environment
■ show iproute ipv6—IPv6 environment
To display the contents of the routing table only for routes of a specified origin, use one of the
following commands:
■ show iproute origin—IPv4 environment
■ show iproute ipv6 origin—IPv6 environment
● That the IP Address Resolution Protocol (ARP) table has the correct entries.
NOTE
The ARP table is applicable only in IPv4 environments.
Use the show iparp command to display the contents of the IP ARP table.
● That the Neighbor Discovery (ND) cache has the correct entries.
NOTE
The ND cache is applicable only in IPv6 environments.
Use the show neighbor-discovery cache ipv6 command to display the contents of the ND cache.
● IP routing protocol statistics for the CPU of the switch.
Only statistics of the packets handled by the CPU are displayed. To display IP statistics for the CPU
of the switch, use one of the following commands:
■ show ipstats—IPv4 environment
■ show ipstats ipv6—IPv6 environment
● Your Open Shortest Path First (OSPF) configuration, including the OSPF area ID, router state, link
cost, OSPF timers, interface IP address, and neighbor list.
NOTE
OSPF is applicable only in IPv4 environments.
Use the following commands to display OSPF information:
■ show ospf—Displays global OSPF information for the switch
■ show ospf area—Displays information related to OSPF areas
■ show ospf area detail—Displays detailed information related to OSPF areas
■ show ospf interfaces detail—Displays detailed information about OSPF interfaces
● Your OSPFv3 configuration, including the OSPFv3 area ID, router state, link cost, OSPFv3 timers,
interface IP address, and neighbor list.
NOTE
OSPFv3 is applicable only in IPv6 environments.
