2.1.

Configuration

The Classification and Filtering feature is configured by specifying the filter selection
combination set in the firmware configuration (t5-config.txt for T5;t4-config.txt for T4) located in
/lib/firmware/cxgb4/
The following combination is set by default and packets will be matched accordingly:
For T5:
i.
filterMode = srvrsram, fragmentation, mpshittype, protocol, vlan, port, fcoe
For T4:
ii.
filterMode = fragmentation, mpshittype, protocol, vlan, port, fcoe
Where,
srvrsram : server-sram
fragmentation: Fragmented IP packets
mpshittype : MAC address "match type" (0=unicast, 1=unicast hash, 2=multicast, 3=multicast
hash, 4=PROM, 5=hyper PROM, 6=broadcast, 7=none)
protocol : IP protocol number (ICMP=1, TCP=6, UDP=17, etc)
vlan : Inner VLAN Tag
port : Packet ingress port number
fcoe : Fibre Channel over Ethernet frames
2.2.

Creating Filter Rules

Network driver (cxgb4) must be installed and loaded before setting the filter rule.
If you haven't done already, run the Unified Wire Installer with the appropriate T5/T4
i.
configuration tuning option to install the Network Driver.
ii. Next, run the following command to load the network driver:
[root@host]# modprobe cxgb4
