To configure aggregated interfaces under LLT by editing the /etc/llttab file

1. If LLT is running, run the following command to stop LLT:
2. Add the following entry to the /etc/llttab file to configure an aggregated interface.

   link tag device_name systemid_range link_type sap mtu_size

   tag	Tag to identify the link
   device_name	Device name of the aggregated interface.
   systemid_range	Range of systems for which the command is valid. If the link command is valid for all systems, specify a dash (-).
   link_type	The link type must be ether.
   sap	SAP to bind on the network links. Default is 0xcafe.
   mtu_size	Maximum transmission unit to send packets on network links

3. Restart LLT for the changes to take effect.

To configure aggregated interfaces under LLT using the lltconfig command

• When LLT is running, use the following command to configure an aggregated interface:

  lltconfig -t devtag -d device 
  [-b linktype ] [-s SAP] [-m mtu]

  devtag	Tag to identify the link
  device	Device name of the aggregated interface.
  link_type	The link type must be ether.
  sap	SAP to bind on the network links. Default is 0xcafe.
  mtu_size	Maximum transmission unit to send packets on network links

  See the lltconfig(1M) manual page for more details.

  You need not reboot after you make this change. However, to make these changes persistent across reboot, you must update the /etc/llttab file.
