Hello,
Anyone know what is the best practices to configure Voice VLAN on 1920 Switch with version 5.20.99.
First of all I define two vlans:
Data (10) and Voice (20)
What are the differences for the following port configs:
interface GigabitEthernet1/0/1
port link-type hybrid
port hybrid vlan 20 tagged
port hybrid vlan 1 untagged
undo voice vlan mode auto
voice vlan 20 enable
port auto-power-down
poe enable
stp edged-port enable
lldp compliance admin-status cdp txrx
lldp voice-vlan 20
and
interface GigabitEthernet1/0/24
port link-type trunk
port trunk permit vlan 1 20
undo voice vlan mode auto
port auto-power-down
poe enable
lldp compliance admin-status cdp txrx
lldp voice-vlan 20
and
interface GigabitEthernet1/0/25
port link-type trunk
port trunk permit vlan 1 20
port auto-power-down
lldp compliance admin-status cdp txrx
lldp voice-vlan 20
I think all the different configuration will carry voice traffic.
So my questions are:
- How can I make sure all Voice Traffic should be trusted? (Assume the IP Phone mark voice bearer traffic with dscp ef and control traffic with cs3
- How can I remark voice as well data traffic in the configurations below with other DSCP values
- On a normal port with untagged vlan I assume all DSCP values will be set to 0?!
- In hybrid mode what happens with VOICE VLAN? Is the voice bearer and control traffic trusted (within the VOICE VLAN)
Thanks
Udo
