Tuning Packet Throughput Performance

You can use the ldm add-vnet and ldm set-vnet commands to set the following data link property values to tune packet throughput performance:

priority

Specifies the CPU packet-processing priority

cos

Specifies the IEEE 802.1p link service class of the link

protection

Specifies packet traffic security type

For information about valid and default property values, see the ldm(8) man page.

Example 50  Setting and Viewing Data Link Packet Properties

The following example shows how to use the ldm set-vnet command to set the priority, protection, and cos property values in a single command. You can also use the ldm add-vnet command to add a new virtual network that uses the specified data link property values.

primary# ldm set-vnet allowed-ips=192.168.100.1,192.168.100.2 \
allowed-dhcp-cids=oracle@system1.company.com, \
00:14:4f:fb:22:79,system2,00:14:4f:fb:22:56 cos=7 priority=high \
protection=restricted,mac-nospoof,ip-nospoof,dhcp-nospoof vnet3_ldg3 ldg3

The ldm list -o network command shows the data link property values on the ldg3 domain that you set with the previous ldm set-vnet command. The protection values are mac-nospoof, restricted, ip-nospoof for the 192.168.100.1,192.168.100.2 MAC address, and dhcp-nospoof for system1@company.com,00:14:4f:f9:d3:88,system2,00:14:4f:fb:61:6e. The priority is set to high and the class of service (cos) is set to 7.
