DESCRIPTION
Resets how long (10-65535 seconds) the Switch waits to
update the DHCP snooping database the first time the
current bindings change after an update to the default
value (300).
Specifies the VLAN IDs for VLANs you want to enable DHCP
snooping on.
Specifies the VLAN IDs for VLANs you want to disable DHCP
snooping on.
Sets the Switch to add the system name to DHCP requests
that it broadcasts to the DHCP VLAN, if specified, or VLAN.
Sets the Switch to not add the system name to DHCP
requests that it broadcasts to the DHCP VLAN, if specified,
or VLAN.
Specifies a pre-defined DHCP option 82 profile that the
Switch applies to the specified port(s) in the specified
VLAN.
Sets the Switch to not apply a DHCP option 82 profile to the
specified port(s).
Sets the Switch to add the slot number, port number and
VLAN ID to DHCP requests that it broadcasts to the DHCP
VLAN, if specified, or VLAN.
Sets the Switch to not add the slot number, port number
and VLAN ID to DHCP requests that it broadcasts to the
DHCP VLAN, if specified, or VLAN.
Specifies a pre-defined DHCP option 82 profile that the
Switch applies to all ports in the specified VLAN.
Sets the Switch to not apply a DHCP option 82 profile to all
ports in the specified VLAN.
Delete all statistics records of DHCP requests going through
the Switch.
Loads dynamic bindings from the default DHCP snooping
database.
Loads dynamic bindings from the specified DHCP
snooping database.
Enables a port or a list of ports for configuration.
Sets this port as a trusted DHCP snooping port. Trusted ports
are connected to DHCP servers or other switches, and the
Switch discards DHCP packets from trusted ports only if the
rate at which DHCP packets arrive is too high.
Sets the maximum rate in packets per second (pps) that
DHCP packets are allowed to arrive at a trusted DHCP
snooping port.
Disables this port from being a trusted port for DHCP
snooping.
Resets the DHCP snooping rate to the default (0).
