Configuring DSCP-based IPv4 Path Detection

Procedure

1. Run system-view

   The system view is displayed.

2. Run ip path detection enable dscp dscp-value

   DSCP-based IPv4 path detection is enabled.

3. Run ip path detection send-packet src-mac src-mac-address dst-mac dst-mac-address [ pe-vlan pe-vlan-id [ 8021p 8021p-value ] [ ce-vlan ce-vlan-id ] ] src-ip src-ip-addr dst-ip dst-ip-address protocol { icmp | { tcp | udp [ gtp-u gtp-teid teid-value ] | sctp } src-port src-port-value dst-port dst-port-value } dscp dscp-value [ vpn-instance vpn-name ] interface { ifType ifNum | ifName } testid test-id

   The ingress is enabled to construct and forward an IPv4 path detection packet.

   

   This step is required only on the ingress for path detection.

4. Run commit

   The configuration is committed.
