Configure LACP Globally on Nortel 8310

[Carolina]

Hi,

What consequences can i have in a production environment if i enable lacp globally?  i have a lot of smlt and mlt configure with others nortels devices, but i need to configure a mlt lacp with other vendor.

Hi Carolina,

please make sure that you haven't additional configured Port-based and/or MLT-based configuration with LACP.
If you enable LACP globally all those ports will be activate LACP as well.
If there is no Port-based and/or MLT-based configuration with LACP available, you're safe to enable LACP globally.

Good luck

Thanks for the reply MatzeKS. I have another problem about LACP. I have this scenario where im trying to bring up a MLT on a Nortel 8310 with a Nexus Cisco. I enable lacp at the interface label on Nortel 8310 but the Cisco switch says that it is not receiving any LACP PDUs and on a packet capute i did not see LACP packet from the Norte switchl. This is the Nortel config and the show commands:


!Configure LACP

config ethernet 1/11 perform-tagging enable
config ethernet 1/11 lacp key 11
config ethernet 1/11 lacp aggregation tru

config vlan 1032 create byport 1

config mlt 3 lacp enable

mmmh, my days with ERS-8300 are over since 8 years 

Your port-based / mlt-based config seems ok, but you have no information with LACP from partner.
You're sure, that you have enabled LACP globally, and your "remote-port" on cisco site is also configured tagged vlan 1032 and LACP?

aggregation : true
lacp : enabled
mode : active

Actually as i dont see that the Nortel is sending any LACP PDUs i assumed that there must be a problem with the configuration.  I just enable LACP at the port label to avoid any inconvenient with others services ports where i have smlt and mlt configuration. In the packet capture i could see that the Cisco switch is sending LACP PDUs, and yes i have lacp and vlan 1032 configured and permit on the  trunking.

again, have you verified that LACP is also globally enabled??

Hi MatzeKs,

I end up configuring the Nortel without LACP and it works pretty well.

Thansk.
