Hello. I’m trying to get an LACP link to come up to a Cisco. I’ve spent too much time looking on Google without the most helpful of results so I’m hoping someone here can help. Here is some of the relevant configuration…
The interfaces on the Cisco:
interface GigabitEthernet1/1/2
switchport mode trunk
logging event trunk-status
channel-protocol lacp
channel-group 10 mode active
interface GigabitEthernet2/1/2
switchport mode trunk
logging event trunk-status
channel-protocol lacp
channel-group 10 mode active
interface Port-channel10
switchport mode trunk
On the VSP:
# LACP CONFIGURATION
#
vlacp enable
lacp smlt-sys-id d4:78:56:xx:xx:xx
lacp enable
# MLT CONFIGURATION
#
mlt 22 enable name "MY-MLT"
# MLT INTERFACE CONFIGURATION
#
interface mlt 22
smlt
lacp enable key 22
exit
interface GigabitEthernet 1/41
name "MLT22"
no shutdown
lacp key 22 aggregation enable
lacp enable
sflow sampling-rate 8192
exit
MY-SWITCH:1(config)#show mlt 22

A message I found in the logs:
