130 CHAPTER 15: IP ADDRESS CONFIGURATIONDisplaying IP AddressConfigurationAfter the above configuration, you can execute the display command in any viewto display the operating status and configuration on the interface to verify yourconfiguration.IP AddressConfigurationExampleNetwork requirementsSet the IP address and subnet mask of VLAN interface 1 to 129.2.2.1 and255.255.255.0 respectively.Network diagramFigure 39 IP address configurationConfiguration procedure# Configure an IP address for VLAN interface 1. system-view[Switch] interface Vlan-interface 1[Switch-Vlan-interface1] ip address 129.2.2.1 255.255.255.0Troubleshooting Symptom: The switch cannot ping the host directly-connected to a port.Solution: You can perform troubleshooting as follows:■ Check the configuration of the switch, and then use the display arpcommand to check whether the host has an corresponding ARP entry in theARP table maintained by the Switch.■ Check the VLAN that includes the switch port connecting the host. Checkwhether the VLAN has been configured with the VLAN interface. Then checkwhether the IP addresses of the VLAN interface and the host are on the samenetwork segment.■ If the configuration is correct, enable ARP debugging on the switch, and checkwhether the switch can correctly send and receive ARP packets. If it can onlysend but cannot receive ARP packets, errors may occur at the Ethernet physicallayer.Table 75 Display IP address configurationOperation Command DescriptionDisplay VLANinterface informationdisplay ip interface [ brief ][ interface-typeinterface-number ]You can execute the displaycommand in any viewSwitchPCConsole Cable
