Using the UDP layer for LLT

■See “Sample configuration: direct-attached links” on page 161.

■See “Sample configuration: links crossing IP routers” on page 163.

Table A-1describes the fields of the link command that are shown in the /etc/llttab file examples. Note that some of the fields differ from the command for standard LLT links.

Table A-1	Field description for link command in /etc/llttab
Field	Description
tag-name	A unique string that is used as a tag by LLT; for example link1,
	link2,....
device	The device path of the UDP protocol; for example udp.
	A place holder string. On other unix platforms like Solaris or HP,
	this entry points to a device file (for example, /dev/udp). Linux
	does not have devices for protocols. So this field is ignored.
node-range	Nodes using the link. "-" indicates all cluster nodes are to be
	configured for this link.
link-type	Type of link; must be "udp" for LLT over UDP.
udp-port	Unique UDP port in the range of 49152-65535 for the link.
	See “Selecting UDP ports” on page 160.
MTU	"-" is the default, which has a value of 8192. The value may be
	increased or decreased depending on the configuration. Use the
	lltstat -lcommand to display the current value.
IP address	IP address of the link on the local node.
bcast-address	■ For clusters with enabled broadcasts, specify the value of the
	subnet broadcast address.
	■ "-" is the default for clusters spanning routers.

The set-addr command in the /etc/llttab file

The set-addrcommand in the /etc/llttab file is required when the broadcast feature of LLT is disabled, such as when LLT must cross IP routers.

See “Sample configuration: links crossing IP routers” on page 163.
