Configuring The Encapsulation Format Of The Management Address; Configuring Cdp Compatibility - H3C LS-3100-52P-OVS-H3 Operation Manual

The configuration does not apply to LLDP-CDP packets, which use only SNAP encapsulation.

Configuring the Encapsulation Format of the Management Address

LLDP encapsulates the management address in the form of numbers or strings in management
address TLVs and then advertises it.
By default, management addresses are encapsulated in the form of numbers in TLVs. If neighbors
encapsulate management addresses in the form of strings in TLVs, you can configure the encapsulation
format of the management address as strings, thus guaranteeing communication with the other devices
in the network.
Follow these steps to configure the encapsulation format of the management address:

Configuring CDP Compatibility

For detailed information about voice VLAN, refer to VLAN Configuration in the Access Volume.
You need to enable CDP compatibility for your device to work with Cisco IP phones.
As your LLDP-enabled device cannot recognize CDP packets, it does not respond to the requests of
Cisco IP phones for the voice VLAN ID configured on the device. This can cause a requesting Cisco IP
phone to send voice traffic without any tag to your device, disabling your device to differentiate the voice
traffic from other types of traffic.
By configuring CDP compatibility, you can enable LLDP on your device to receive and recognize CDP
packets from Cisco IP phones and respond with CDP packets carrying the voice VLAN configuration
