# e.g.

# endpoint {

# interface=eth2.5

# port = 8000 vlan = 5 priority=1

# }

# endpoint { interface=eth2 port=9999}

# endpoints that bind to port 0 (requesting the host allocate a port)

# can be accelerated with port=0:

# endpoint {interface=eth1 port=0}

Assume your T5/T4 interface is eth2. To accelerate all applications that preload libcxgb4_sock

using eth2, you only need one entry in /etc/libcxgb4_sock.conf:

endpoint {interface=eth2 port=0}

If you have eth2 and eth3 configured for example, you can define certain endpoints to eth2 and

others to eth3:

endpoint {interface=eth2 port=9999}

endpoint {interface=eth3 port=8888}

For VLAN support, create your VLANs using the normal OS service (like vconfig, for example),

then add entries to define the VLAN and priority for each endpoint to be accelerated:

endpoint {interface = eth2.5 port=10000}

endpoint {interface = eth2.7 priority=3 port=9000}

Now, preload libcxgb4_sock:

[root@host]# CXGB4_SOCK_CFG=<path to config file>

LD_PRELOAD=libcxgb4_sock.so <pathto>/your_application

In order to offload IPv6 UDP sockets, please select “low latency networking” as

T5/T4 configuration tuning option during installation.
