Chapter 7: LACP Port Trunks

unknown destination.
 Prior to creating an aggregate trunk between an Allied
Telesis device and another vendor’s device, refer to
the vendor’s documentation to determine the
maximum number of active ports the device can
support in a trunk. If the number is less than eight, the
maximum number for the AT-GS950/48PS switch, you
should assign the other vendor’s device a higher
system LACP priority than your AT-GS950/48PS
switch. This can help avoid a conflict between the
devices if some ports are placed in the standby mode
when the devices create the trunk. For background
information, refer to “System Priority” on page 107.
 LACPDU packets are transmitted as untagged
packets.
