Refer to the exhibit.
An HP Comware Switch connects to Voice over (VoIP) phones. The phones connect to user’s
computes, so each switch port connects a computer and a phone.
These are the specifications:
The VLAN for data traffic is VLAN3
The VLAN for traffic VoIP is VLAN11
The phones support Link Layer Discovery Protocol (LLDP) Media Endpoint Detection (MED).
The network administrator wants to use LLDP-MED to advertise the voice VLAN ID and priority
settings to the phones. The phones will then send tagged traffic in that VLAN. The switch should
not check the incoming traffic’s MAC address against its voice OID list. The exhibit shows the
applicable switch port configuration.
Which additional step must the administrator complete to accomplish this?
A.
Enable voice VLAN 11 (voice vlan 11 enable)
B.
Change the port to trunk mode (port link-type trunk)
C.
Enable LLDP compatibility with Cisco Discovery Protocol (CDP) (lldp compliance admin-status cdp txrx)
D.
Enable the port to advertise voice VLAN 11 with LLDP (lldp voice-vlan 11)
Explanation:
On this page, https://community.hpe.com/t5/Comware-Based/Can-t-find-quot-voice-vlan-enable-quot-on-an-A5500-switch/td-p/6097427
Look what Peter_Debruyne say,
“As a general note, if the phones support LLDP-MED, it is recommended to use the interface command lldp voice vlan x and configure the port as a hybrid/trunk with the voice vlan as tagged in a static way.”
So D is correct answer.
