Split Trunking Support with HP Auto Port Aggregation
# conf mlt 31 smlt create smlt-id 31
Step 3: Enable LACP on all the switch ports in the aggregation.
Now that the SMLT has been defined on both switches, LACP is enabled on the switch ports. Because
you are using switch ports 2/31 and 2/32 on both switches, the commands to enable LACP on the
switch ports are identical for both switches as follows:
Switch1# conf ether 2/31-2/32 lacp key 31
Switch2# conf ether 2/31-2/32 lacp aggregation true
Switch3# conf ether 2/31-2/32 lacp enable
Step 4: On the HP-UX 11i v3 server side, create the LACP link aggregation lan900 using ports
lan9, lan10, lan11, and lan12 using key=900 as follows:
# nwmgr –s –A key=900 –c lan900
# nwmgr –s –S apa –A key=900,mode=LACP_AUTO –c lan9
# nwmgr –s –S apa –A key=900,mode=LACP_AUTO –c lan10
# nwmgr –s –S apa –A key=900,mode=LACP_AUTO –c lan11
# nwmgr –s –S apa –A key=900,mode=LACP_AUTO –c lan12
For information about the nwmgr APA commands, see the APA Administrators Guide for HP-UX 11i
v3.
