2. Usage

2.1.

Configuration

The Classification and Filtering feature is configured by specifying the filter selection
combination set in the firmware configuration file t6-config.txt (t5-config.txt and t4-config.txt for
T5 and T4 adapters respectively).
The following combination is set by default and packets will be matched accordingly:
filterMode = fragmentation, mpshittype, protocol, vlan, port, fcoe
Where,
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 (if_cxgbe) and cxgbetool must be installed before setting the filter rule.
Run the following command to load the network driver:
[root@host~]# kldload if_cxgbe
Now, create filter rules using cxgbetool:
[root@host~]# cxgbetool t6nexY filter <index> action [pass/drop/switch]
Where,
t6nexY : Chelsio T6 interface. Use t5nexY and t4nexY for T5 and T4 adapters respectively.
index : positive integer ranging from 0-495 set as filter id.
