ONS 15530 and Etherchannel

[lorenzocucchetti]

Hi,

I have 4 ONS 15530 with 8GE modules, on 4 port ( 2 local and 2 and remote end) I would like to connect 2 6509 in etherchannel configuration.

I tested all configuration possible and the best config that I found is :

ONS : Negotiation auto

Laser control forward Enable

6500 : Negotiation enable

UDLD enable ( NO udld aggressive)

etherchannel PAGP

With this configuration I performed some tests ( some below)

1) 6500 Giga-TX down = NO problem

2) 6500 Giga-RX down = stp loop problem and the 2 trunks go down(error disable).

It seem a UDLD problem.

Someone know how to configure udld with ONS in ethrchannel configuration ??

thank you

ciao

Lorenzo

set udld enable 2/1-2,2/4 can be used with the ONS 15454, but I have not been able to find the equivalent command for 15530. Here is the link to the command reference.

I didn't find it too. I think in 15530 UDLD is enabled by default, but from information that I have.. udld is local, isn't end-to-end.

Someone know more info about udld in 15530 ??
