Setting Up An Openflow Virtual Service; Enabling Openflow - Cisco Nexus 5600 Series Configuration Manual

Configuring OpenFlow
Template Based TCAM Carving for OpenFlow
The Cisco Nexus device supports template-based TCAM carving. To configure OpenFlow on the device, you
must make a number of changes to the TCAM carving regions using the template based TCAM carving
commands.
To support higher scale numbers for OpenFlow policies, the IFACL-region of the TCAM must be recarved
accordingly. To apply TCAM carving for a maximum flow scale, enter the following commands:
switch(config)#
switch(config-tcam-templ)# vacl 64
switch(config-tcam-templ)# ifacl 3520
switch(config-tcam-templ)# qos 128
switch(config-tcam-templ)# rbacl 64
switch(config-tcam-templ)# span 64
switch(config)# hardware profile tcam resource service-template openflow
Enter the following command to verify the TCAM carving: show hardware profile tcam resource template
tmplt-name
Configuring TCAM carving requires that the Cisco Nexus device be reloaded.
Note

Setting Up an OpenFlow Virtual Service

The virtual service manager allows you to enable the OpenFlow agent application to run as a virtual service
on a container. To setup a virtual service for OpenFlow you must perform the following tasks:
• Download the application OVA package to your system.
• Install the OVA package for a named virtual service. For example:
• Configure and activate the virtual service. For example:
To upgrade a software package installed on a virtual service you use the virtual-service upgrade name
application-name package file-url command.
An active virtual service can not be updated.
Note
To remove a software package installed on a virtual service you use the virtual-service uninstall name
application-name command.
An active virtual service can not be removed.
Note

Enabling OpenFlow

OpenFlow capability is enabled by entering the hardware profile openflow command to allocate the hardware
resources required for the OpenFlow agent. Following a switch reload, the hardware profile command is
OL-31641-01
hardware profile tcam resource template openflow
switch#virtual-service install name openflow-agent package file-url
switch(config)#virtual-service openflow-agent
switch(config-virt-serv)#activate
