Check Switch Status (Oracle ILOM)
Packets received at the switch can be classified to a particular class of service based on the filters configured. Certain policies can be applied before forwarding the packets. The following task illustrates the classification of the TCP packets received in the switch and changing the DSCP value in the IP header of the TCP packets to 46.
See Basic SEFOS Topology for the topology of this task. Connect port 1 to host A and port 2 to host B. Host B should have a command to dump traffic over a network interface such as tcpdump or snoop. If not, port 1 and port 2 can be connected to a data capturing device as shown in Basic SEFOS Topology.
See Connect to SEFOS.

46 (0x2e) is a decimal number. If an 8-bit TOS value is shown, it is shown as 0xb8 because 0x2e must be shifted left 2 bits to get the 6 bits of the DSCP value.

From host A to host B, send TCP packets to host B and use the host-supported packet dumping command to verify the DSCP value.
# tcpdump -xx -n -i eth3 ip ... 16:34:27.979962 IP 12.0.0.100.905 > 12.0.0.17.shell: ... 16:34:27.980163 IP 12.0.0.17.shell > 12.0.0.100.905: 0x0000: 0014 4f6c 7de9 001b 2147 d479 0800 4500 0x0000: 001b 2147 d479 0014 4f6c 7de9 0800 45b8 ...
These packets are received at Port 2 and have a DSCP value 46. In this example, the dump command shows a DSCP value of 0xb8.
