I have an issue configuring QoS on voice vlan.
I did the following config :
lldp global enable voice-vlan track lldpvlan 31 name ToIP description ToIPinterface GigabitEthernet1/0/17 port link-type trunk port trunk permit vlan 1 10 port trunk pvid vlan 10 voice-vlan qos 5 46 voice-vlan 31 enable stp edged-port poe enable#interface GigabitEthernet1/0/19 port link-type trunk port trunk permit vlan 1 10 31 qos trust dscp***********
IP phone is on port 1/0/17 and 1/0/19 is an uplink (trunk)
I expected to have vlan 31 outbound frames on int g1/0/19 being correctly vlan tagged and marked at L2 and L3.
When I capture what's in and out of 1/0/19, I see the phone frames correctly tagged as vlan 31, but no CoS or DSCP are marked (all at 0)
Here are the things I verified :
[TEST]dis voice state Current voice VLANs: 1 Voice VLAN security mode: Security Voice VLAN aging time: 1440 minutes Voice VLAN enabled ports and their modes: Port VLAN Mode CoS DSCP GE1/0/17 31 AUTO 5 46[TEST]dis mac-addr vlan 31MAC Address VLAN ID State Port/NickName Aging0080-9f91-cb09 31 VOICE-VLAN GE1/0/17 Y[TEST]dis mac-addr int g1/0/17MAC Address VLAN ID State Port/NickName Aging0019-b97c-dcf2 10 Learned GE1/0/17 Y0080-9f91-cb09 31 VOICE-VLAN GE1/0/17 Y[TEST]dis vlan 31 VLAN ID: 31 VLAN type: Static Route interface: Configured IPv4 address: 192.168.3.1 IPv4 subnet mask: 255.255.255.0 Description: ToIP Name: ToIP Tagged ports: GigabitEthernet1/0/17 GigabitEthernet1/0/19 Untagged ports: None
My question is : do I need to set a QoS policy ? I expected the automatic voice vlan config to do all the QoS stuff without additionnal config steps...
Have a nice day.
(on HPE 5130 EI "comware" switch)
I finally found the solution (with the help of my co-worker) : you MUST create a OUI reference for the phone model.
voice-vlan mac-address mac-address mask oui-mask [ description text ]
Without this, the switch will not consider incoming frames as "voice", even if LLDP has told the phone to put them in the right VLAN.
So, LLDP does NOT insert OUI records in the table, it just tells the phone that there is a voice vlan and it's number.
