About LLT directives in /etc/llttab file
Table: LLT directives lists the LLT directives in /etc/llttab file for LLT over Ethernet.
Table: LLT directives
Directive | Description |
---|---|
set-node | Assigns the system ID or symbolic name. The system ID number must be unique for each system in the cluster, and must be in the range 0-63. The symbolic name corresponds to the system ID, which is in /etc/llthosts file. Note that LLT fails to operate if any systems share the same ID. |
set-cluster | Assigns a unique cluster number. Use this directive when more than one cluster is configured on the same physical network connection. LLT uses a default cluster number of zero. |
link | Attaches LLT to a network interface. At least one link is required, and up to eight are supported. LLT distributes network traffic evenly across all available network connections unless you mark the link as low-priority using the link-lowpri directive or you configured LLT to use destination-based load balancing. The first argument to link is a user-defined tag shown in the lltstat(1M) output to identify the link. It may also be used in llttab to set optional static MAC addresses. The second argument to link is the device name of the network interface. Its format is device_name:device_instance_number. The remaining four arguments to link are defaults; these arguments should be modified only in advanced configurations. There should be one link directive for each network interface. LLT uses an unregistered Ethernet SAP of 0xcafe. If the SAP is unacceptable, refer to the llttab(4) manual page for information on how to customize SAP. Note that IP addresses do not need to be assigned to the network device; LLT does not use IP addresses in LLT over Ethernet mode. |
link-lowpri | Use this directive in place of link for public network interfaces. This directive prevents VCS communication on the public network until the network is the last link, and reduces the rate of heartbeat broadcasts. If you use private NICs with different speed, use "link-lowpri" directive in place of "link" for all links with lower speed. Use the "link" directive only for the private NIC with higher speed to enhance LLT performance. LLT uses low-priority network links for VCS communication only when other links fail. |
For more information about the LLT directives, refer to the llttab(4) manual page.
