Ip dhcp snooping database flash

DHCP Snooping Commands 4

This command writes all dynamically learned snooping entries to flash memory.

Command Mode

Global Configuration

Command Usage

This command can be used to store the currently learned dynamic DHCP snooping entries to flash memory. These entries will be restored to the snooping table when the switch is reset. However, note that the lease time shown for a dynamic entry that has been restored from flash memory will no longer be valid.

Example

Console(config)#ip dhcp snooping database flash

Console(config)#

show ip dhcp snooping

This command shows the DHCP snooping configuration settings.

Command Mode

Privileged Exec

Example

Console#show ip dhcp snooping

Global DHCP Snooping status: disable

DHCP Snooping is configured on the following VLANs: 1
