106 Confidential and Proprietary Information of ZTE CORPORATION
1. In ordinary mode, after sending Hello neighbor joining packet,
the received Echo packet displays that the peer port's neighbor
is not itself.
2. In aggressive mode, after sending Hello neighbor joining
packet, the received Echo packet displays that the peer port's
neighbor is not itself.
3. In aggressive mode, after receiving Hello neighbor joining
packet, send Echo packet and the peer Echo packet is not
received.
4. In aggressive mode, all neighbors in the interface exceed the
aging time and don't receive Hello detection packet. When
interface is down or the interface can't be used, this device
need to send a flush packet to inform the adjacent layer 2
device to delete the information of this device.
Enable UDLD protocol, the receiving echo packet displays the peer
port's neighbor is not itself, which indicates fault connection. No
matter what mode UDLD applies, the port will be shutdown.
Aging time means protocol packet sending interval (the default is
15 seconds)*3. If aggressive mode is configured, packet is not
recieverd when exceed aging time, port will be shutdown.

Configuring UDLD

UDLD Global Configuration

Udld enable/disable <port-list>

no udld recovery timer <port-list>
Function
This globally enables UDLD or
enables UDLD in batch.
This sets protocol packet
sending interval.
This recovers default protocol
packet sending time.
This recovers interface up
automatically for the reason
that UDLD causes interface
down (the default is not
recovery).
This sets the time when the
interface is recoverd as up
automatically for the reason
that UDLD causes interface
down (the default is 30s).
This sets 30s to recover
interface up automatically for
the reason that UDLD causes
interface down.
