26.2.2 E 2 E-TC Setting

The following diagram shows a sample E2E-TC configuration.

Figure 26-3: Sample E2E-TC Configuration

Points to note

Set PTP interface's VLAN ID and IPv4 address as VLAN ID and IPv4 address that are set on VLAN interface. To minimize variations in the forwarding delay for PTP messages, set PTP message priority (CoS) of the Switch to 7 (highest priority).

Note that PTP must be enabled on all ports that send and receive PTP messaging.

Command examples

1. (config)# interface vlan 100

   Create VLAN ID 100 as a ported VLAN. It also enters VLAN configuration mode.

2. (config-if)# ip address 192.168.1.1 255.255.255.0

   (config-if)# exit

   Set VLAN100 to IPv4 192.168.1.1 and subnet mask 255.255.255.0.

3. (config)# ptp source-interface vlan 100 ip-address 192.168.1.1

   Sets 192.168.1.1 as VLAN 100,IPv4 for PTP interfaces.

4. (config)# ip qos-flow-list PTP_PRIORITY

   (config-ip-qos)# qos udp any host 224.0.1.129 range 319 320 action cos 7

   (config-ip-qos)# exit

   Creates a IPv4 QoS flow list (PTP_PRIORITY) and sets PTP messaging frame preference to 7.

5. (config)# interface range tengigabitethernet 1/0/1-3

   Switches to the interface mode of ports 1/0/1 to 1/0/3.

6. (config-if-range)# switchport mode access

   (config-if-range)# switchport access vlan 100

   Sets port 1/0/1 to 1/0/3 as the access port. Also, set VLAN 100.

7. (config-if-range)# ptp enable

   Enables PTP on ports 1/0/1 through 1/0/3.

8. (config-if-range)# ip qos-flow-group PTP_PRIORITY in

   (config-if-range)# exit

   Enables the receiving IPv4 QoS flow list (PTP_PRIORITY) on ports 1/0/1 to 1/0/3.

9. (config)# ptp run e2e-tc

   Sets the Switch to E2E-TC.

10. (config)# save

    (config)# exit

    Saves the settings and moves from configuration mode to administrator mode.
