Enabling a Catena Instance

• egress-port-group epg-name—Specifies the egress port group.

• egress-device-group edg-name—Specifies the egress device group.

• mode mode—Specifies the mode types—drop, bypass, or forward—for the received packets.

Currently, you must configure separate instances for Layer 2 and Layer 3 modes. A catena instance can

comprise multiple chains that are independent of each other. The traffic in each chain is forwarded as defined.

However, if there is an overlap between packets from different chains at the ingress port, then all the chains

configured on that ingress interface will be evaluated. If a match is found on the ingress interface, then the

matching chain is accepted and forwarded.
