Page 12: Information About Catena
Catena provides a hardware-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 firewall, IPS, IDS, DOS Protection, WAAS, SSL offload engines, networking monitoring devices, switches, virtual appliances, and containers. -
Page 13: Benefits Of Catena
If you create an appliance cluster, then the traffic is equally distributed to these appliances. Deployment Modes This section describes the various modes in which the Catena solution can be deployed. Cisco Nexus 7000 Series Switches Configuration Guide: The Catena Solution... -
Page 14: Transparent Mode
Catena uses source IP or destination IP to determine the egress interface. Egress interface ports are bundled using the link aggregation control protocol (LACP), and hash algorithms are used for symmetric load balancing. Cisco Nexus 7000 Series Switches Configuration Guide: The Catena Solution... -

Catena. Enabling or Disabling the Catena Solution By default, Catena is disabled on the Cisco NX-OS device. You must explicitly enable Catena to configure and verify the authentication commands. Ensure that you have installed the enhanced Layer 2 package license. -

Step 4 Configure load balancing using the hash-based method: switch(config-port-group)# load-balance port-channel Step 5 (Optional) Copy the running configuration to the start up configuration: switch(config)# copy running config startup-config Cisco Nexus 7000 Series Switches Configuration Guide: The Catena Solution... -
Page 17: Configuring A Vlan Group
Step 2 Create a device group and enter device-group configuration mode: switch(config)# catena device-group device-group-name Step 3 Assign nodes to the configured device group: switch(config-device-group)# node {ip ipv4-address | IPv6 ipv6-address} Cisco Nexus 7000 Series Switches Configuration Guide: The Catena Solution... -
Page 18: Configuring A Port Acl
Port ACLs (PACLs) are used as filters in transparent mode. They are used to seggregate IP traffic for transparent mode PACL. The traffic is redirected to a particular egress interface based on the access control entries (ACE). Cisco Nexus 7000 Series Switches Configuration Guide: The Catena Solution... -
