Viewing OSPF packet statistics for a subnet or VLAN

Displays the statistics on OSPF packets sent and received on the interfaces in VLANs and/or subnets on an OSPF-enabled routing switch, including the number of errors that occurred during packet transmission. Enter the command at any CLI level.

Syntax: 


show ip ospf interface [[vlan vlan-id] | ip-address]

Displays the following information for OSPF-enabled VLANs and/or subnets:

vlan-id

Displays OSPF packet statistics for all subnets configured on the VLAN.

ip-address

Displays OSPF packet statistics only for a specified VLAN subnet.
