Setting An Encapsulation Format For Lldp Frames; Configuring Cdp Compatibility - H3C S5830V2 series Configuration Manual

Step
4. Set the token bucket size for
sending LLDP frames.
5. Set the LLDP frame
transmission delay.
6. Set the number of LLDP frames
sent each time fast LLDP frame
transmission is triggered.
7. Set an interval for fast LLDP
frame transmission.

Setting an encapsulation format for LLDP frames

LLDP frames can be encapsulated in the following formats:
Ethernet II—With Ethernet II encapsulation configured, an LLDP port sends LLDP frames in Ethernet
•
II frames.
SNAP—With SNAP encapsulation configured, an LLDP port sends LLDP frames in SNAP frames.
•
LLDP of earlier versions requires the same encapsulation format on both ends to process LLDP frames. To
communicate stably with a neighboring device running LLDP of earlier versions, the local device must be
configured with the same encapsulation format.
To set the encapsulation format for LLDP frames to SNAP:
Step
1. Enter system view.
2. Enter Layer 2/Layer 3
Ethernet interface view,
management Ethernet
interface view, or Layer
2/Layer 3 aggregate
interface view.
3. Set the encapsulation
format for LLDP frames to
SNAP.

Configuring CDP compatibility

When the switch is directly connected to a Cisco device that supports only CDP rather than LLDP, you can
enable CDP compatibility to enable the switch to exchange information with the directly-connected
device.
