Chapter 13 Network Management Configuration
has defined a recommendatory update frequency, that is, the up-
date messages should be sent every 30 seconds.
Optional TLV contains a basic management TLV set, an IEEE 802.1-
organized particular TVL, and an IEEE 802.3-organized particular
TVL.
The appearance of LLDPUD ending TLV means the end of the LLD-
PDU.
Configuring LLDP
To configure LLDP, perform the following steps.
Step Command
Function
1
ZXR10(config)#
lldp enable
This enables LLDP.
2
ZXR10(config)#
lldp hellotime
<
seconds
>
This configures the interval of
sending LLDPDUs.
3
ZXR10(config)#
lldp holdtime
<
multiple
>
This configures the aging
time of LLDPDU. The product
of parameters multiple and
hellotime is aging time.
4
ZXR10(config)#
interface
<
interface-name
>
This enters interface
configuration mode.
5
ZXR10(config-if)#
lldp setAdminStatus
{
enabledtxrx
|
rxonly
|
txonly
|
disabled
}
This configures the
management state of LLDP.
LLDP Configuration Example
This example shows how to configure LLDP.
As shown in
Figure 36
, S1 connects to S2. Configure LLDP on the
two switches to make them discover each other.
