Parameters
interface-type interface-number: Specifies an interface by its type and number.
Usage guidelines
Use the display ip interface command to display IP configuration and statistics for the specified Layer 3 interface. The statistics include the following information:
The number of unicast packets, bytes, and multicast packets the interface has sent and received.
The number of TTL-invalid packets and ICMP packets the interface has received.
The packet statistics helps you locate a possible attack on the network.
If you do not specify an interface, the command displays information about all Layer 3 interfaces.
Examples
# Display IP configuration and statistics for VLAN-interface 10.
<Sysname> display ip interface vlan-interface 10 Vlan-interface10 current state : DOWN Line protocol current state : DOWN Internet Address is 1.1.1.1/8 Primary Broadcast address : 1.255.255.255 The Maximum Transmit Unit : 1500 bytes input packets : 0, bytes : 0, multicasts : 0 output packets : 0, bytes : 0, multicasts : 0 TTL invalid packet number: 0 ICMP packet input number: 0 Echo reply: 0 Unreachable: 0 Source quench: 0 Routing redirect: 0 Echo request: 0 Router advert: 0 Router solicit: 0 Time exceed: 0 IP header bad: 0 Timestamp request: 0 Timestamp reply: 0 Information request: 0 Information reply: 0 Netmask request: 0 Netmask reply: 0 Unknown type: 0
