ip dhcp snooping database flash

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

show ip dhcp snooping

This command shows the DHCP snooping configuration settings.

Command Mode

Privileged Exec

Example

Console(config)#ip dhcp snooping database flash

Console(config)#
