[c-nsp] LACP Trunk between Cisco VSS and Brocade MLX.

[Harry Hambi - Atos]

Hi Frank,
Please find attached information requested.
I've tried disabling lacp rate fast no joy. The working half of the trunk has this command enabled.

Cisco ------1/3/45 ------MLX 3/19        non-working trunk
Cisco ------1/3/46 ------MLX 3/20


Cisco ------2/3/45--------MLX 8/19     working trunk.
Cisco ------2/3/46--------MLX 8/20

Thanks for sharing.  Could you please share the Cisco interface configs (Po345 and each of the LAG members)?

Note that the Cisco is set to use fast while Brocade is set to use slow.  I would start with setting them the same.

Hi James,
Yes good idea, please find attached configuration of Cisco & Brocade switches. Not much on the Brocade end see attached.
The ports with the error message LACP-BLOCKED are 3/19 & 3/20  on the Brocade end.

Config snippets would be useful.

Yes, I have checked config of working Trunk and no difference.

yes, it's normally caused by misconfiguration.  Both brocade netiron and
cisco IOS have mature 802.3ad/LACP implementations which interoperate nicely.
