Performing Basic LLDP Configuration 1187
c
CAUTION: To enable local device information to be updated on neighboring
devices before being aged out, make sure the interval to send LLDPDUs is shorter
than the TTL of the local device information.
Setting the number of the LLDPDUs to be sent when a new neighboring
device is detected
Follow these steps to set the number of the LLDPDUs to be sent when a new
neighboring device is detected
Configuring the
Encapsulation Format
for LLDPDUs
The Switch 4800G can encapsulate LLDPDUs in Ethernet II or SNAP frames. You
can configure either encapsulation at the CLI for interoperability with the remote
device.
■ With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in
Ethernet II encapsulation and processes only Ethernet II encapsulated incoming
LLDPDUs.
■ With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP
encapsulation and processes only SNAP encapsulated incoming LLDPDUs.
Follow these steps to configure the encapsulation format for LLDPDUs:
To do… Use the command… Remarks
Enter system view System-view -
Set the interval to send
LLDPDUs
lldp timer tx-interval value Optional
30 seconds by default
Set the delay period to send
LLDPDUs
lldp timer tx-delay value Optional
2 seconds by default
To do… Use the command… Remarks
Enter system view system-view -
Set the number of the
LLDPDUs to be sent
successively when a new
neighboring device is
detected
lldp fast-count value Optional
3 by default
To do… Use the command… Remarks
Enter system view system-view -
Enter Ethernet
interface view or
port group view
Enter Ethernet
interface view
interface interface-type
interface-number
Either of the two is
required.
Configuration performed in
Ethernet interface view
applies to the current port
only; configuration
performed in port group
view applies to all the ports
in the corresponding port
group.
Enter port group
