Translation from SF300-24P to 3650ios

[dekelley01]

I received a config from my vendor that they usualy put on a SF300 for their managed voice.  Looks like you configure general ports and PVID's to allow two vlans on one port. Is this the same as switchport voice vlan <vlanid> ?

Also in the configuration I see the following

voice vlan id 20
voice vlan state disabled
voice vlan oui-table add 0001e3 Siemens_AG_phone________
voice vlan oui-table add 00036b Cisco_phone_____________
voice vlan oui-table add 00096e Avaya___________________
voice vlan oui-table add 000fe2 H3C_Aolynk______________
voice vlan oui-table add 0060b9 Philips_and_NEC_AG_phone
voice vlan oui-table add 00d01e Pingtel_phone___________
voice vlan oui-table add 00e075 Polycom/Veritel_phone___
voice vlan oui-table add 00e0bb 3Com_phone______________

This config won't work on my 3550 and 3560 switches.  It seems this is some auto vlan config, how would this translate on a 3550 or a 3560? or is it needed at all?

Hi Devin, to configure 3560 for voice vlan may be something like this-

config t

mls qos

int gi0/1

mls qos trust cos

switchport voice vlan x dot1p

With such example this will configure port 1 with trusting class of service using 802.1p (4 bit header in packet) to use voice vlan with tag packet

hi tom, thanks for the reply, what about the OUI table configs, is this needed is there a translation for this to a 3550 /60?

[Tom Watts]

For oui translation there is a switchport voice detect command. I'm not sure if there's any additional syntax for this, I believe there is. I believe "cisco-phone" is the only option by default.

Is the OUI table really needed? Also I see you used the dot 1p option.  This is for priority tagging right? wouldn't untagged more closely rep. the switchport mode general?

[Tom Watts]

Hi Devin. The OUI table is not needed. That is just an alternate method to implement voice VLAN if you chose not to use SX300 macro.

General port is a 802.1q trunk, it's not relevant to priority tagging. Priority tagging is based off a tag VLAN packet to accept the 4 bit VPT header to prioritize traffic. Port mode has no effect on this so long as it's a tagged packet.
