Hello,
I am having difficulties with SG300 28P after upgrading from 1.3.5.58 (boot image sx300_boot-13506.rfb) to 1.3.7.18 and also 1.4.0.88 (boot image sx300_boot-13506.rfb). On 1.3.5.58 I had configuration that had next configuration:
vlan database
vlan 60,104
exit
voice vlan id 60
voice vlan state oui-enabled
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______________

switchport trunk allowed vlan add 60,104
macro auto disabled
This configuration worked perfectly when I switched over cable from PC to VoIP telephone and vice versa. PC fell into 104 vlan and VoIP phone fell into 60 VLAN without problems every time I switched from one to another the same cable.
The problem started when I upgraded to the following ios versions 1.3.7.18 and 1.4.0.88. When I switch cable in PC I get IP configuration from DHCP server from vlan 104 and when I switch the same cable in VoIP phone it takes IP configuration from VoIP DHCP server on vlan 60. But when I switch back the same cable to PC I don't get DHCP configuration from DHCP server from vlan 104. This function was available in version 1.3.5.58. In newer versions it is not available for same general port to share different vlans when voice vlan is enabled. I tried with putting that port in trunk mode and it works but this is not solution for our company because this would not have voice vlan enabled, it would be more statical configuration.
Can you tell me is this a bug in new versions or did the configuration for general mode with voice vlan changed in some way?
