Bond interface and LACP on Cisco

marcinw — Tue, 20 Apr 2021 11:40:53 GMT

I am going to create bond interface on 1550 and port channel on 3850 , I have two vlans 35 and 194 , on 1550 I've picked up 802.3ad on bond, also network unassigned, however I get message on 3850 There is no LACP interface on the other site . All networks are disabled, when I try UP bond interface I get message that it can't be done on unassigned network. 1550s configuration screenshot in attachment, what do I configure wrongly on 1550s ?

How is the lacp in the 3850 switch? For LACP (802.3ad) in the 1550 it should be an ACTIVE port-channel in cisco side.

HI,

Yes it is ACTIVE on CIsco side, there is no problem with trunk on single 1550s interface, but portchannel seems to be dodgy or not working at all. I tried in GNS and it is working on Openserver and Gaia 80.30 without any problems
