No ip dhcp snooping database Default Configuration Use the no form of this command to delete the DHCP Snooping binding database file. Use the ip dhcp snooping database Global Configuration mode command to enable the DHCP Snooping binding database file. Switchxxxxxx(config)# ip dhcp snooping verify ip dhcp snooping database Port matches the client hardware address. The following example configures a device to verify that the source MAC address in a DHCP packet received on an untrusted The switch verifies that the source MAC address in a DHCP packet received on an untrusted port matches the client hardware No ip dhcp snooping verify Default Configuration Use the no form of this command to disable MAC address verification in a DHCP packet received on an untrusted port. Use the ip dhcp snooping verify Global Configuration mode command to configure a device to verify that the source MAC address in a DHCP packet received onĪn untrusted port matches the client hardware address. switchxxxxxx(config)# ip dhcp snooping information option allowed-untrusted ip dhcp snooping verify The following example allows a device to accept DHCP packets with option-82 information from an untrusted port. No ip dhcp snooping information option allowed-untrusted Default ConfigurationĭHCP packets with option-82 information from an untrusted port are discarded. Ip dhcp snooping information option allowed-untrusted Use the no form of this command to drop these packets from an untrusted port. Use the ip dhcp snooping information option allowed-untrusted Global Configuration mode command to allow a device to accept DHCP packets with option-82 information from an untrusted port. Switchxxxxxx(config-if)# ip dhcp snooping trust ip dhcp snooping information option allowed-untrusted The following example configures gi1/0/4 as trusted for DHCP Snooping. Configure the ports thatĪre connected to DHCP clients as untrusted. Interface (Ethernet, Port Channel) Configuration mode User GuidelinesĬonfigure as trusted the ports that are connected to a DHCP server or to other switches or routers. No ip dhcp snooping trust Default Configuration Use the no form of this command to restore the default configuration. Use the ip dhcp snooping trust Interface Configuration (Ethernet, Port-channel) mode command to configure a port as trusted for DHCP snooping purposes. switchxxxxxx(config)# ip dhcp snooping vlan 21 The following example enables DHCP Snooping on VLAN 21. Command ModeĭHCP Snooping must be enabled globally before enabling DHCP Snooping on a VLAN. No ip dhcp snooping vlan vlan-id ParametersĭHCP Snooping on a VLAN is disabled. Use the no form of this command to disable DHCP Snooping on a VLAN. Use the ip dhcp snooping vlan Global Configuration mode command to enable DHCP Snooping on a VLAN. switchxxxxxx(config)# ip dhcp snooping ip dhcp snooping vlan The following example enables DHCP Snooping on the device. DHCP Snooping on a VLAN is notĪctive until DHCP Snooping on a VLAN is enabled. Global Configuration mode User Guidelinesįor any DHCP Snooping configuration to take effect, DHCP Snooping must be enabled globally. No ip dhcp snooping Default Configuration Use the ip dhcp snooping Global Configuration mode command to enable Dynamic Host Configuration Protocol (DHCP) Snooping globally. ip dhcp snooping information option allowed-untrusted.This chapter contains the following sections: IP Routing Protocol-Independent Commands.I don't follow the purpose of a bunch of the code you have there. SubList is your object type, but you decided to make your arrays object rather than SubList You seem to have all sorts of issues there. Public SubListItem(string key, string value) Public class SubList : ObservableCollection Here's the class used for the binding: public class MainList : ObservableCollection I need to create a control where I can bind a list of lists, but am having trouble understanding the binding.
