Configs are different which one is best?

[eferland]

This is he switch I just configured.

!

interface GigabitEthernet1/0/46

switchport mode access

switchport voice vlan 20

srr-queue bandwidth share 1 30 35 5

priority-queue out

mls qos trust device cisco-phone

mls qos trust cos

auto qos voip cisco-phone

spanning-tree portfast

spanning-tree bpduguard enable

service-policy input AUTOQOS-SRND4-CISCOPHONE-POLICY

!

This is a switch thats been in production for about a year.

!

interface GigabitEthernet1/0/19

switchport mode access

switchport voice vlan 20

srr-queue bandwidth share 10 10 60 20

queue-set 2

priority-queue out

mls qos trust cos

auto qos voip trust

spanning-tree portfast

!

Is one better then the other? Which if any are best practices?

BTW, they both seem to work the same with a Cisco IP spa525g phone connected to a PC.

Newer versions of iOS are going to have differing port macros. Practically I don't think you'll notice anything different between the two, except that bpduguard is recommended if you're going to run portfast.
