DESCRIPTION
"Loops may cause broadcast storms. The purpose of loopback detection
is to detect loops on the device and to protect the network."

DESCRIPTION
"Added new nodes to configure the loop detection."
REVISION "200903301741Z"
DESCRIPTION
"To fix bugs in the MIB file."

Hh3cLpbkdtActionType ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Loopback detection action on the port on which a loop is detected.
When a loop is detected on a port, the device generates a log. The
enumeration 'none(1)' means that the device performs no action on the
port. The enumeration 'block(2)' means that the device disables MAC
address learning and blocks traffic on the port. The enumeration
'nolearning(3)' means that the device disables MAC address learning on
the port. The enumeration 'shutdown(4)' means that the device shuts
down the port. The device automatically sets the port to the forwarding
state after the time interval configured."

lowest numbered VLAN. Thus, each VLAN is represented by a single bit
within the value of this object. A bit with a value of '1' indicates
that the loop detection is enabled globally for the VLAN; the loop
detection is disabled globally for the VLAN if its bit has a value of
