ProSafe M4100 and M7100 Managed Switches
See show ip ospf interface stats on page 297 for a sample output of the number of OSPF
packets of each type sent and received on the interface.
show ipv6 ospf neighbor
This command displays information about OSPF neighbors. If you do not specify a neighbor
IP address, the output displays summary information in a table. If you specify an interface or
tunnel, only the information for that interface or tunnel displays. The <ip-address> is the IP
address of the neighbor, and when you specify this, detailed information about the neighbor
displays. The information below only displays if OSPF is enabled and the interface has a
neighbor.
Format show ipv6 ospf neighbor [interface {<slot/port> | tunnel
<tunnel_id>}][<ip-address>]
Modes
• Privileged EXEC
• User EXEC
LSA Acks
Received
The total number of LSA acknowledged from this interface.
LSA Acks Sent
The total number of LSAs acknowledged to this interface.
Sent Packets

The number of received OSPF packets whose version field in the OSPF header does not
match the version of the OSPF process handling the packet.
Virtual Link Not
Found

s sender.
Area Mismatch
The number of OSPF packets discarded because the area ID in the OSPF header is not
the area ID configured on the ingress interface.

not the address of the ingress interface and is not the AllDrRouters or AllSpfRouters
multicast addresses.
No Neighbor at
Source Address
The number of OSPF packets dropped because the sender is not an existing neighbor or
the sender’s IP address does not match the previously recorded IP address for that
neighbor. NOTE: Does not apply to Hellos.
