telephones with computers directly connected to them are configured as trunk ports with VLAN

21 as the native VLAN and VLAN 20 as a static-VLAN (see port 1/11).

C360-1(super)# set vlan 20 name ipoffice-voice

C360-1(super)# set vlan 21 name ipoffice-data

C360-1(super)# set vlan 70 name s8500-voice

60-1(super)# set vlan 71 name s8500-data

C360-1(super)# set port vlan 20 1/2-3

C360-1(super)# set port vlan 21 1/11

C360-1(super)# set trunk 1/11 dot1q

C360-1(super)# set port static-vlan 1/11 20

The port connecting the C363T-PWR to the X450-24T is configured with 802.1q with vlan-

binding-mode to the configured VLANs.

C360-1(super)# set port vlan 20 1/24

C360-1(super)# set trunk 1/24 dot1q

C360-1(super)# set port vlan-binding-mode 1/24 bind-to-configured

6.2. Configure QoS

The Avaya C363T-PWR Stackable Switch supports four hardware queues. The 802.1p/Q or

Class of Service (CoS) to queue assignment is as follows:

Q1 Q2 Q3 Q4

CoS

0,1 2,3 4,5 6,7

In the test configuration, the Avaya C363T-PWR Stackable Switch is used as a Layer 2 Switch.

The Avaya C363T-PWR Stackable Switch will mark all traffic from the IP Office with 802.1p/Q

priority value 6 and will prioritize VoIP traffic for the Avaya IP telephones based on 802.1p/Q

priority. In the test configuration, the 802.1p/Q priority value 6 from the IP telephones will be

mapped to the highest priority queue. The Avaya C363T-PWR Stackable Switch supports

weighted round robin or strict priority queuing scheme. The strict priority queuing scheme is

used in the test configuration.

C360-1(super)# set port level 1/3 6

C360-1(super)# set queuing scheme strict

If the Avaya C363T-PWR Stackable Switch needs to be configured as a Layer 3 router, QoS

must be enabled for Layer 3. The C363T-PWR Stackable Switch can be configured to trust

802.1p/Q priority (CoS) or DSCP or both for Layer 3 traffic. The following shows how to

configure the C363T-PWR Stackable Switch to trust CoS and DSCP. This QoS rule would still

need to be applied to a Layer 3 interface. Layer 3 routing is not used in these Application Notes.
