Hello,
Wanting to ask the great wisdom of this group regarding an port-channel question.
Have 2 3750x switches I'm trying to create a port channel between.
interface GigabitEthernet1/1/1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-protocol lacp
channel-group 1 mode active
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
I've tried using GLC-T copper SFPs on a 10G expansion module (both switches have a module). first with just the 1 and 3 gig ports then with all. Every try, whether it's with just the 1 and 3 ports, all 4, doesn't seem to matter. I can the error Gi1/x/x suspended: LACP currently not enabled on the remote port.
Pretty obvious it's enabled. have defaulted and re-configured the ports and the port channel multiple times.
Last try was to move one end of the connections to non sfp ports, so in this case gig1/0/1-4.
I finally got 1 port to come up in the channel
1 Po1(SU) LACP Gi1/1/1(P) Gi1/1/2(s) Gi1/1/3(s) Gi1/1/4(D)
but I still get the LACP errors in the log.
The end goal is to have this with a dual fiber link but it's really making me wonder what its going on if when I get the fiber sfps and cable if I'll run into the same issue. copper sfps are causing the issue?
Kinda of future fact searching for the moment, but if anyone could share some insight.
----
forgot to mention, I haven't migrated the 4 connections to regular gig ports on the other switch. will try and get that this evening.
