deploying cisco ip phone using non-cisco switch?

Hi Experts,

My understanding is that the cisco switch will tell the cisco phone which vlan to tag the voice traffic via CDP (correct me if i got it wrong), so when deploying cisco IP phone using non-cisco switch, what is the typical approach to instruct the phone which vlan to tag the voice? Thanks for advise.

Cheers,

Da

Hi Da,

I didn't test LLDP-MED with Cisco Phones, but newer phones must support it by default. We choose in the CUCM to enable or disable it.

Hi Da,

Cisco Phones with Third-Party Switches:

In this case, Cisco phones must be individually provisioned (through the phone interface) with their voice VLAN information.

Both LLDP-MED and Cisco Discovery Protocol support this capability. LLDP-MED provides finer control of the network policy by allowing separate control for signaling and bearer applications. However, from a practical point of view, the critical capability is the VLAN configuration, and it is supported by both Cisco Discovery Protocol and LLDP-MED.

Hope it helps, if it does please rate.

Best regards,

Hi Adrian,

Thanks for sharing the info. Individual provisioning the phone seems impossible when there are thousands of phones to be provisioned, do you know if there is any more scalable approach? Or we can only pray that the 3rd party switch happens to do the magic using LLDP-MED like cisco does using CDP?

Thanks Adrian,I will check with the 3rd party switch vendor and see if they do voice vlan configuraiton using LLDP.
