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 13-12 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.
