Looking for some help for straight forward VOIP configuration (PC plugged into Phone plugged into access interface) on EX switch.
I taught the data vlan just needs to be configured on an access interface as the interfaces only vlan member and the voice vlan/interface needs to be configured under "switching-options voip". However this document
contradicts that and shows an extra step where the interface is also configured in switch-options underneath the VLAN. Similar in ways to how non-els voip configuration was done. E.g
I originally taught this was a mistake in the document but have found the same configuration it in at least one other reference (the JNCIE-ENT Self study bundle).
So can any explain why the interface being configured for the VOIP vlan needs to be configured under both Switch-options->Voip and also under vlan->vlan-name->switch-options. Need to know for exam purposes, in practice I have deployed this without the vlan->vlan-name->switch-options and it seems to work just fine.
Greetings, I can confirm and guarantee that this portion of the configuration is not needed:
Not sure why it is there but again it is not needed for VoIP, and there is a lot of documentation that does not have this configuration, the official Juniper training material for JNCIP-ENT does not have this configuration either.
The switch-option under the VLAN hierarchy is used to configure Layer 2 learning and forwarding properties for a set of bridge domains/vlan such as the following:
None of these are needed or related to VoIP minimum required configuration.
If this solves your problem, please mark this post as "Accepted Solution" so we can help others too \:)/
