Testing Traffic Probe
Action
Step Action
1 In the Test Sets (TS), provision the ports shown in Figure 7-11 on page 7-53
with the following:
• TS1: SA - SA1, DA - DA1
• TS3: SA - SA3, DA - DA3
2 Ensure that when packets are being transmitted from TS1, they are received
by TS3, and vice versa. This would require that the VCG-3 be provisioned
with some bandwidth. Also, all the three ports have to be in the same VLAN.
3 Go to Switches Port Mirroring. Click Provision a new PortMirroring from View
PortMirroring preview pane.
4 Select Enable from Port Mirroring Mode drop-down menu.
5 Select Eth-1 from Source Ports drop-down menu and Eth-2 from Destination
Port drop-down menu.
6 Provision the port Eth-2 as a port mirror to Eth-1. In the options given for the
traffic direction, select the option 'Both' which would mean that packets from
both the client side and the network side would get mirrored.
7 Now, if traffic is transmitted from TS1, a copy of the frames should be received
at TS2. The number of frames transmitted from Eth-1 should match the
number of frames received at TS2. On viewing the contents of the frames
received at Eth-2, the contents should reflect the same contents as the
frames transmitted from TS1.
8 Apply ingress port limiting on NEA-ETH1. Start transmission from TS1 with
the rate > port limiting rate, and ensure that the frames are received on TS2
at the rate, at which the ingress port limiting is applied.
9 Similarly, stop the transmission of traffic from TS1, and start the transmission
of traffic from TS3. As this traffic is also mirrored to Eth-2, the frames should
get mirrored towards Eth-2. The number of frames transmitted from TS3,
should match the number of frames received at Eth-2. As traffic is now
received from Eth-1-Egress side, all the traffic from egress side, which is
Testing Traffic Probeintended to go Eth-1 will get mirrored to Eth-2 before
entering the VLAN block of the switch that is if frames are untagged
transmitted from TS3, Eth-2(NE-1) will receive a single tagged frame with
PVID of NE2-ETH1.
10 Apply egress port limiting on NEA-ETH1. Ensure that CIR is less than the BW
provisioned. Start transmission from TS3 with the rate > port limiting rate, and
ensure that the frames are received on TS2 at the rate, at which the egress
port limiting is applied.
11 On TS2, start the transmission of frames towards the port Eth-2. The frames
should get dropped on the port as it is provisioned as a probe port.
