4-16 CHAPTER 4: COMMANDSBasic IP Commands Table 4-13 describes basic IP commands.Table 4-13 Basic IP CommandsCommand Descriptionshow ipconfig {vlan [ | all]} Displays configuration information for one or moreVLANs, including the following:n IP address, subnet maskn IP forwarding informationn BOOTP configurationn VLAN name, VLANidshow ipstats {vlan [ | all]} Displays statistics of packets handled by the CPU,including the following:n inpackets, outpacketsn ICMP/IGMP statisticsn IRDP statisticsshow ipfdb { | vlan | all}Displays the contents of the IP forwarding databasetable. Use for technical support purposes.clear ipfdb [ | vlan | all]Allows you to clear the dynamic entries in the IPforwarding database table.enable ipforwarding {vlan | all} Allows you to enable IP forwarding to an IPinterface. If “all” is specified, then all theconfigured IP interfaces are affected. If no optionalargument is provided, the “all” is assumed. Other IPconfiguration is not affected. When new IPinterfaces are added, the interface is configured tohave ipforwarding disabled by default.disable ipforwarding {vlan | all} Allows you to disable IP forwarding on one or all IPinterfaces.enable ipforwarding broadcast{vlan | all}Allows you to enable forwarding of IP broadcasttraffic on an IP interface. If “all” is specified, then allthe configured IP interfaces are affected. If nooptional argument is provided, then “all” isassumed. Other IP configuration is not affected.When new IP interfaces are added, the default is tohave broadcast enabled.disable ipforwarding broadcast{vlan | all}Allows you to disable IP broadcast forwarding onone or all IP interfaces.enable bootp vlan [ | all] Allows you to enable the generation and processingof BOOTP packets on a VLAN. The default setting isenabled for all VLANs.(continued)
