Hi I have below network:
VoIP PABX1 | | FE | Cisco Catalyst 2960 (sw1) / Office 1 | | GE | Cisco Catalyst 6503 (sw2) | | GE | Cisco Catalyst 3560G (sw3) | | GE | Cisco Catalyst 2960 (sw4) / Office 2 | | FE | VoIP PABX2 I have to provide QoS for traffic between VoIP PABX1 and VoIP PABX2. Computers are in VLAN101, Servers and PABX on VLAN102. I have computers and servers on both sides on SW1 and SW4 as well. I tried below configuration: 1) sw1, 2960 mls qos ! interface FastEthernet0/6 description VoIP_PABX_1 switchport access vlan 100 switchport mode access load-interval 30 mls qos cos 7 mls qos trust cos no cdp enable spanning-tree portfast ! interface GigabitEthernet0/1 description TRUNK to SW2 switchport mode trunk load-interval 30 no cdp enable mls qos trust cos 2) sw2, 6503/Sup32 interface GigabitEthernet1/3 description TRUNK to SW1 switchport mode trunk load-interval 30 no cdp enable mls qos trust cos ! interface GigabitEthernet1/6 description TRUNK to SW3 switchport mode trunk load-interval 30 no cdp enable mls qos trust cos ! 3) sw3, 3560G interface GigabitEthernet0/11 description TRUNK to SW2 switchport mode trunk load-interval 30 no cdp enable mls qos trust cos ! interface GigabitEthernet0/12 description TRUNK to SW4 switchport mode trunk load-interval 30 no cdp enable mls qos trust cos ! 4) sw4, 2960 interface FastEthernet0/21 description VoIP_PABX_1 switchport access vlan 100 switchport mode access load-interval 30 mls qos cos 7 mls qos trust cos no cdp enable spanning-tree portfast ! interface GigabitEthernet0/1 description TRUNK to SW3 switchport mode trunk load-interval 30 no cdp enable mls qos trust cos ! Unfortunately we have problems with communications between both PABXes. Suppiler said that there is problem in our Ethernet network Is our QoS configuration is correct ? Should be move both IP PABXes to separate VLAN instead of using Servers VLAN ?
