Your output says the JNPR side is still fast/1s.
I'd actually prefer to look at the LACP PDU from the wire 'monitor traffic '
Flap would be expected if CSCO sends every 30s, JNPR sends every 1s.
We should expect JNPR to be happy about 3s after receiving PDU from
CSCO. I thoroughly recommend
Hi
I've deactivated the FAST on Juniper but nothing changes...
As I wrote on Cisco remains down hence you will not see any LACP while on
Juniper it flaps, once I shut on cisco it stop to flap
I'm not sure it is a cabling issue...
we should try to setup a pure L3 p2p link and test that I guess...
You've changed JNPR from 30s to 1s, but not CSCO. I'm not sure if this
is the only problem, as insufficient data is shown about the state and
LACP PDUs.
I believe the command is 'lacp rate fast' or 'lacp period short', to
reduce risk of operators getting bored, In your case, the former.

Depends. If you have access to the end hosts and it's a single TCP
session (which can only be on 1 link) you can craft or calculate the

I think there's definitely value in putting some thought into any
numbering/naming scheme you use anywhere, but the answer you come up
with will depend on your organization and the situation.

We don't have a formal port channel naming schema. I usually use 1-10
for things like ISLs between core and stuff and then start with 11-XXX
for all the port channels to various downstream devices. That said, the
