LACP and NS480

Firstly, welcome to the forums, and above all, thank you for being an EMC customer.

Please consider moving this question as-is (no need to recreate) to the proper forum for maximum visibility.  Questions written to the users' own "Discussions" space don't get the same amount of attention and can go unanswered for a long time.

LACP is a standary protocol based on IEEE 802.3ad. Both VNX and Brocade ethernet switch support LACP protocol, so I think NS480 are able to connect with Brocade ethernet. When troubleshooting trunks, make sure the following rules for trunk formation have been considered:

•  Any number of ports between 2 and 12 within the same chassis can be used to configure a trunk port.
•  Ports in a trunk must have the same speed, negotiation mode, and Quality of Service (QoS) priority or the trunk is rejected.
•  All ports configured in a trunk must be configured with the same port attributes.
•  Primary port policy applies to all secondary ports. No trunk is rejected.
•  The trunk is rejected if any trunk port has mirroring or monitoring configured.
•  The trunk is rejected if any trunk port has VLAN or inner-VLAN translation configured (also known as VLAN trunking).

Below is some common diagnostic scenarios
•  LACP trunk links may not operate properly between Brocade devices and third-party devices because of a mismatch between the link configurations. If the link is fixed on the third-party side, the link on the Brocade side must be a trunk. If it is link-aggregated on the third-party side, then it must be the same on the Brocade side.
•  LACP links may not operate properly due to misconfigurations.

If you feel my answer is helpful, please help me to mark it. It's very import for me. Thanks.

The Celerra supports both Cisco EtherChannel as well as the standard LACP (Link Aggregation Control Protocol).  There are some minor differences between them.  When looking to implement aggregation you should check your switches to see if they allow a group of aggregates to span multiple physical switches.

I noticed you have encountered some issues when you configure the LACP, the thread of "Celerra network configuration best practices" provides some suggestion for configurating the tolerant interface. However, I think the problem is from the Brocade switch. Maybe you can check the relevant log in the brocade switch. I would like to provide the Command Reference Manual for your reference :http://www.brocade.com/downloads/documents/html_product_manuals/NOS_CLI_301/wwhelp/wwhimpl/js/html/wwhelp.htm#href=commands_a_z.4.167.html

The problem was not configuring LACP.  I have LACP properly configured on the VDX switch.  I am using LACP to connect other devices which have no issues.  I even contacted Brocade support who had us run a debug on the switch to inspect the traffic and no LACP traffic was coming on the ports and they immediately shutdown.  Do you know of anyone who is using Brocade ethernet switches with NS480 and LACP?

The problem as it turns out was LACP config on the VDX switch.  You have to manually specify the speed of 1000 on the Port channel interface if using 1Gb/s physical interfaces.

Thanks for the feedback
