Now, preload libcxgb4_sock_debug using the command mentioned below when starting your

application:

root@host]# LD_PRELOAD=libcxgb4_sock_debug.so CXGB4_SOCK_DEBUG=-1

<pathto>/your_application

In addition to preloading libcxgb4_sock.so, you must create a configuration file that defines

which UDP endpoints should be accelerated, their vlan and priority if any, as well as which

T5/T4 interface/port should be used. The file /etc/libcxgb4_sock.conf contains these

endpoint entries. Create this file on all systems using libcxgb4_sock. Here is the syntax:

# Syntax:

# endpoint {attributes} ...

# where attributes include:

# interface = interface-name

# port = udp-port-number

# vlan = vlan-id

# priority = vlan-priority

# 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}
