VSP Switch Clustering with 3rd Party Switches

RiaanvS — Thu, 23 Apr 2020 16:42:18 GMT

Hi. Does anyone have standards/config for a VSP cluster connection to 3rd party switch cluster with LACP? The 3rd party will be HP/Aruba or Dell switches. I see some loops when 1 of the 3rd party switches are rebooted. Any ideas perhaps?

Thx.

Hi,

Never forget to disable spanning tree on SMLT links.

I use this to MLT+LACP for a Cisco switches:

mlt 137 enable name TO-CISCO-SWITCH1
mlt 137 encapsulation dot1q
mlt 138 enable name TO-CISCO-SWITCH2
mlt 138 encapsulation dot1q

interface mlt 137
smlt
lacp enable key 137
exit

interface mlt 138
smlt
lacp enable key 138
exit

interface GigabitEthernet 1/37
default-vlan-id 0
name "TO-CISCO-SWITCH1"
lacp key 137 aggregation enable partner-key 137 partner-port-priority 32768 partner-system-priority 32768 timeout-time short
lacp enable
no spanning-tree mstp force-port-state enable
y
exit

interface GigabitEthernet 1/38
default-vlan-id 0
name "TO-CISCO-SWITCH2"
lacp key 138 aggregation enable partner-key 138 partner-port-priority 32768 partner-system-priority 32768 timeout-time short
lacp enable
no spanning-tree mstp force-port-state enable
y
exit

And I used this to MLT+LACP to a Cisco router

# MLT CONFIGURATION
mlt 203 enable name CiscoRouter
mlt 203 encapsulation dot1q
interface mlt 203
smlt
lacp enable key 203
exit
#
# VLAN CONFIGURATION
vlan mlt 100 203
vlan mlt 101 203
vlan mlt 110 203
vlan mlt 115 203
vlan mlt 246 203

# PORT CONFIGURATION - PHASE II
#
interface GigabitEthernet 2/3
lacp key 203 aggregation enable
lacp enable
exit

Thank you Mig.

On the VSP side spanning-tree was disabled. I found that the Dell switch side was not. Also the Dell side was running spanning-tree mode VLAN instead of port which I changed. This seems to have solved the issue.
