The maximum TTL value allowed by CDP is 255 seconds. To make CDP-compatible LLDP work properly
with Cisco IP phones, make sure that the product of the TTL multiplier and the LLDPDU transmit interval is
less than 255 seconds.

Configuring DCBX

DCE, also known as CEE, is enhancement and expansion of traditional Ethernet local area networks for
use in data centers. DCE uses the DCBX to negotiate and remotely configure the bridge capability of
network elements.
DCBX has two self-adaptable versions, DCB Capability Exchange Protocol Specification Rev 1.0 and DCB
Capability Exchange Protocol Base Specification Rev 1.01. DCBX offers the following functions:
Discovers the peer devices' capabilities and determines whether devices at both ends support these
•
capabilities.
Detects configuration errors on peer devices.
•
Remotely configures the peer device, if the peer device accepts the configuration.
•
DCBX is supported only on the 10-GE ports of HP 5820X series Ethernet switches, and only the remote
configuration function is supported.

switch. DCBX enables the switch to control the server adapter, and simplifies the configuration and
guarantees configuration consistency. DCBX extends LLDP by using the IEEE 802.1 organizationally
specific TLVs (DCBX TLVs) to transmit DCBX data, including PFC, ETS, and APP
