User Guidelines
This MIB specifies the Voice Vlan ID (VVID) to which this port belongs:
• 0—The CDP packets transmitting through this port contain Appliance
VLAN-ID TLV with value of 0. VoIP and related packets are expected to be
sent and received with VLAN-ID=0 and an 802.1p priority.
• 1..4094—The CDP packets transmitting through this port contain Appliance
VLAN-ID TLV with VLAN-ID=N. VoIP and related packets are expected to be
sent and received with VLAN-ID=N and an 802.1p priority.
• 4095—The CDP packets transmitting through this port contain Appliance
VLAN-ID TLV with value of 4095. VoIP and related packets are expected to
be sent and received untagged without an 802.1p priority.
• 4096—The CDP packets transmitting through this port do not include
Appliance VLAN-ID TLV; or, if the VVID is not supported on the port, this MIB
object will not be configurable and will return 4096.
Example
switchxxxxxx(config)# cdp appliance-tlv enable
8.6 cdp mandatory-tlvs validation
Use the cdp mandatory-tlvs validation Global Configuration mode command to
validate that all mandatory (according to the CDP protocol) TLVs are present in
received CDP frames. The no format of this command disables the validation.
If the mandatory TLVs are not included in the packet, it is deleted.
Syntax
cdp mandatory-tlvs validation
no cdp mandatory-tlvs validation
