Setup
In the diagram
below, two SAR-Ms are connected together via hybrid ports. Traffic is generated
by IXIA.
Figure 1 - Network setup
Prerequisites
-
Network setup as shown
in the diagram above.
-
Hybrid port mode is
configured on the ports connecting SAR-M-143 and SAR-M-144.
-
IGP and MPLS enabled.
-
Distributed Epipe
service 100 is for the network traffic.
-
Local Epipe service 200
is configured for the management traffic.
-
Node SAR-M-143 Config:
Configure port mode to be
“hybrid” and apply shaper policies:
The “encap-type”
needs to be set to “dot1q”.

Configure the network side and
the access side on port 1/1/7:
VLAN 100 carries network traffic, whereas
VLAN 200 carries management traffic. The underlying IGP and MPLS configurations
are not shown here. They need to be configured properly to get the service
operationally up.

Note: SAR-M-144 has a similar
configuration.
Hybrid port
stats: since the traffic
generator is sending more than the configured egress-rate, the drop counter is
incrementing.
Note: “egress
queue stats” from “show port xxx detail” is for the network port only.
