[c-nsp] udld fail ?

Tue May 31 09:15:54 EDT 2016

dear experts
I've a Cisco 6500 (12.2(33)) connected to a juniper EX4200 with a 2 x 10Gb
port channel.

Apparently the Cisco gear has disabled one out of the two ten giga
interface after some flapping of the other one and due to UDLD that is
currently non configured as aggressive nor bidirectional (not supported by
Juniper gear).

Among the two gears LACP fast is running.

I kindly ask any feedback if it's something already experienced by somebody.

Cheers
James
