Voice Data VLAN config options

Configure cnMatrix to connect IP phone

Update 4/16/2022: In 4.2, the feature Automated Voice VLAN automates the manual configuration described in this article once a VLAN is designated as ‘voice vlan’. In adddition, when the phone is removed from the port, the entire configuration is reverted for security enhancement eg. voice vlan is removed from the port etc. Refer to the 4.2 Release Note, and 4.2 CLI User Guide for the instruction to set the voice vlan via CLI/Web. CLI: EX2010P# ! EX2010P(config)# vlan 1000 EX2010P(config-vla…

Do you have any information on the Voice Data VLAN configuration options within cnMaestro, as of version 4.0.1-r2?

I have the automated voice VLAN enabled in cnMaestro as above, but it doesn’t appear the switch is “advertising” the configuration.

Running, show lldp neighbor detail , returns the following from an attached AudioCodes phone.

Note how NetworkPolicy is listed under Capabilities Supported but not in Capabilities Enabled, would that be due to the phone or the switch?

Lastly is it possible to advertise location information via LLDP, these phones (Microsoft Team) use when emergency calls are placed to route to the right location so could save a life potentially!
