CFM-1.1: CFM over ETHoCWoMPLSoGRE

Summary

This test verifies CFM "DOWN MEP" can be established over "EthoCWoMPLSoGRE" dataplane.

Testbed type

• featureprofiles/topologies/atedut_8.testbed

Procedure

Test environment setup

DUT has an ingress and 2 egress aggregate interfaces.
                         
    [ ATE Port 1 ]----| Port1  :DUT1:  Port2 | ---- |Port2 :DUT2: Port1 | ---- |ATE Port 2 |  

Test uses aggregate 802.3ad bundled interfaces (Aggregate Interfaces).

• Ingress Port: nTraffic is generated from Aggregate1 (ATE Ports 1).

• Egress Ports: Aggregate2 (ATE Port 2) is used as the destination ports for encapsulated traffic.

• Transit Ports: Aggregate3 (DUT1 port 2 and DUT2 Port 2)

CFM-1.1.1: Generate DUT Configuration

Aggregate 1 and Aggregate2 i.e "customer interface's" are the customer facing ports that could either have port mode configuration or attachment mode configuration as described below.

EACH test should be run twice - once with port mode configuration and once with attachment in sub-interface mode configuration.

port mode configuration implies CFM configured on main Port as an attachment and vlan-mode is when cfm is confirued between attachments on ansub-interface.

Port mode will have Link loss forwarding enabled while sub-interface mode may not.

Aggregate 1 "customer interface" Port mode configuration

• Configure DUT1 port 1 to be a member of aggregate interface named "customer interface"
• "customer interface" is a static Layer 2 bundled interface part of pseudowire that accepts packets from all VLANs.
• MTU default 9216

Aggregate 1 "customer interface" Attachment mode configuration

• Configure DUT1 port 1 to be a member of aggregate interface named "customer interface"
• Create a sub interface of the aggregated interface and assign a VLAN ID to it.
• This sub interface will be a static Layer 2 bundled interface part of pseudowire that accepts packets from vlan ID associated with it.
• MTU default 9216

Aggregate 2 "customer interface" Port mode configuration

• Configure DUT2 port 1 to be a member of aggregate interface named "customer interface"
• "customer interface" is a static Layer 2 bundled interface part of pseudowire that accepts packets from all VLANs.
• MTU default 9216

Aggregate 2 "customer interface" Attachment mode configuration

• Configure DUT2 port 1 to be a member of aggregate interface named "customer interface"
• Create a sub interface of the aggregated interface and assign a VLAN ID to it.
• This sub interface will be a static Layer 2 bundled interface part of pseudowire that accepts packets from vlan ID associated with it.
• MTU default 9216

Policy Forwarding Configuration

• Policy-forwarding enabling EthoMPLSoGRE encapsulation of all incoming traffic:

  • The forwarding policy must allow forwarding of incoming traffic across 16 tunnels. 16 Tunnels has 16 source address and a single tunnel destination.

  • Source address must be configurable as:

    • Loopback address OR
    • 16 source addresses corresponding to a single tunnel destinations to achieve maximum entropy.

  • DSCP of the innermost IP packet header must be preserved during encapsulation

  • DSCP of the GRE/outermost IP header must be configurable (Default TOS 96) during encapsulation

  • TTL of the outer GRE must be configurable (Default TTL 64)

  • QoS Hardware queues for all traffic must be configurable (default QoS hardaware class selected is 3)

Pseudowire (PW) Configuration

• "Customer interface" is Aggregate 1 and Aggregate 2 pointing towards Aggregare3
• Two unique static MPLS label for local label and remote label.
• Enable control word

Aggregate 3 configuration

• IPV4 and IPV6 addresses

• MTU (default 9216)

• LACP Member link configuration

• Lag id

• LACP (default: period short)

• Carrier-delay (default up:3000 down:150)

• Statistics load interval (default:30 seconds)

Routing

• Create static route for tunnel destination pointing towards Aggregate 2.
• Static mapping of MPLS label for encapsulation must be configurable

MPLS Label

• Entire Label block must be reallocated for static MPLS
• Labels from start/end/mid ranges must be usable and configured corresponding to EthoMPLSoGRE encapsulation

CFM

CFM is cnfigured as UP MEP. The control plane is between the customer attachments on either PF.

CFM-1.1.2: Verify PF CFM establishment over EthoMPLSoGRE encapsulate

• Configure CFM session on DUT1 Port 1 and DUT2 Port 1 at line rate with a mix of both IPV4 and IPv6 traffic. Use 64, 128, 256, 512, 1024 MTU bytes frame size.
• Adjacent ATE Ports must have an Active L2.

Verify:

• CFM session is established with default timers and All ccm PDUs are EthoCWoMPLSoGRE-encapsulated.
• Verify deadtimer at 3.5 (100ms --> 350ms) times the configured keepalive.
• CCM PDUs are constant flows hence are not ECMP'd across all available tunnels.

Run the test separately for both port mode and attachment mode "customer interface" configuration.

CFM-1.1.3: Verify PF CFM packet integrity

• Use same configuration profile as CFM-1.1.2 (Default Timers).

Verify:

• CCM PDU Destination is Multicast.
• CFM OpCode as - Continuity check message (1).
• Increasing sequence number for consequent CCM packets.
• Verify interval field in CCM packet for following fields.
• Transmitted interval 100ms.
• Max Lifetime 350ms.
• Min lifetime 325ms.

CFM-1.1.3.1: Verify PF CFM Alarm

• Use same configuration profile as CFM-1.1.2
• Configure Wrong MD level on on endpoint.
• Revert MD level and configure different CCM interval (i.e 100ms and (10ms or 1s))

Verify:

• “wrong MD level” alarm (when induced) on the endpoints.
• Verify “wrong interval” alarm (when induced) on the endpoints.

CFM-1.1.4: Verify RDI bit set for CCM PDUs on a CE-PE fault

• Use configuration profile as descrbied in CFM-1.1.2
• turn off TX/Shutdown ATE port 1 (only on one endpoint).

Verify:

• CCM PDU is recieved on the remote endpoint with the RDI flag Set.
• A "Remote Defect Detected" alarm is raised at the remote end-point.

CFM-1.1.5: Verify RDI bit set for CCM PDUs on a PE-PE fault

• Use same configuration profile as descrbied in CFM-1.1.2.
• turn off DUT 1 port 2 (only one endpoint).

Verify:

• Both DUT 1 and DUT 2 observe a CCM timeoute Event
• DUT 1 and DUT 2 emit a CCM PDU with the RDI flag Set.

CFM-1.1.5.1: Verify TX actuation on a remote defect or a CCM timeout

• Use configuration profile as describedd in CFM-1.1.2 (Port mode only).
• turn off TX/Shutdown ATE port 1 (only on one endpoint).
• revert TX on ATE port 1 and turn off DUT 1 port 2 (only one endpoint).

Verify:

• CCM PDU is recieved on the remote endpoint with the RDI flag Set.
• A "Remote Defect Detected" alarm is raised at the remote end-point.

CFM-1.1.6: Verify CFM Loss threshold can be configrued on DUT

• Use configuration profile as describedd in CFM-1.1.2.
• re-write defulat Loss threshold (3) knob to 6, 10 , 20, 100 and 255.
• Shutdown DUT 1 port 2 (only one endpoint).

CFM-1.1.8: Verify CFM Delay measurement.

• Use configuration profile as described in CFM-1.1.2.
• Configure 2 way DM measurement profiles on CFM session with 60 second measurement intervals.

Verify:

• DUT 1 and DUT 2 observe a min, max and mean Delay measurements at defined.

CFM-1.1.9: Verify CFM synthetic loss measurement).

• Use configuration profile as described in CFM-1.1.2.

Verify:

• Both DUT 1 and DUT 2 observe a min, max and mean frame loss ratio for "far-end" & "near-end" with 60 second measurement intervals.

CFM-1.1.10: Verify CFM scale.

• Use configuration profile as describedd in CFM-1.1.2.
• Configure 1000 attachments, pseudowires and Establish 1000 CFM sessions between operating at 100ms keepalive:

Verify:

• Device Health and soak for at least 6 hrs.
