Is it possible to configure two different VLANs for VoIP, on an MS350 switch, for two different model IP phones on the same port? We’ve got different headers on the DHCP scopes, but I can’t see an easy way to add more than one VLAN ID on the config screen!
Have you tried configuring the switch ports as Trunk rather than Access? This allows multiple VLAN IDs to be entered.
We have the ports configured already with a data VLAN and VoIP VLAN, for existing Avaya phones and PCs. We need to allow for Cisco phones to now be used on a separate VLAN, ideally across all ports.
You can have multiple VLANs on a switch port configured as Trunk -
. . . use a trunk port as suggested by @Uberseehandel.
. . . it's also not very secure.
How is explicitly allowing only specified VLAN traffic on a switch port "not very secure"?
You cannot take single components of an overall network design and pontificate on whether or not a feature is "secure".
