Error: This MLT is used for legacy MLT VSP4900-48P

Hi, I am unable to enable LACP on my MLT links. The error is as below:

Error: This MLT is used for legacy MLT

Is this a limitation or did i miss out something? MLT works fine but i would like to further explore it with LACP. Thanks

Hi ongxc,

LACP is not compatible with legacy MLT.

You must remove the ports from the MLT and you’ll be able to configure LACP.

Here a sample config:

#Enable LACP active mode on LACP

#

# MLT CONFIGURATION

mlt 203 enable name ROUTER

mlt 203 encapsulation dot1q

interface mlt 203

smlt

lacp enable key 203

exit

#

# VLAN CONFIGURATION

vlan mlt 100 203

...

vlan mlt 246 203

# PORT CONFIGURATION - PHASE II

interface GigabitEthernet 2/3

lacp key 203 aggregation enable

lacp enable

exit
