Configuring the Catena Solution

This chapter describes how to configure Catena on a Cisco NX-OS device.

Catena provides hardware (TCAM) based application chaining solution for Cisco Nexus devices so that

packets can be redirected through multiple physical or virtual devices without changing the topology or the

existing configuration. The solution works with all L4-L7 virtual and physical devices, such as firewalls, IPS,

IDS, DOS Protection, WAAS, SSL offload engines, networking monitoring devices, switches, virtual appliances,

and containers.

Catena allows you to create several chains with multiple elements in each chain. You can configure security

policies to specify segments of traffic through a particular chain. For example, an element could be a cluster

of devices, in which case, catena load-balances to the cluster. Catena performs health monitoring and failure

handling of devices.

Some of the key features of Catena are as follows:

Note

Catena supports IPv4 and IPv6 addresses.
