Re: connect between Cisco N5k vs Dell blade

quynhln8 · ‎06-16-2024

I have 1 blade DELL and 2 switch cisco n5k e1/37-40 <=> Te0/49-52

with N5k-1 & vsys01-dell, use port channel 4 member, any work normal

but with N5k-2 & vsys02-dell, only 1 port working, 3 other port status up but protocol down

show int po1 in DELL switch, only 1 member port te0/49

I follow guide

but still nothing change
with DELL M1000e, only 1 member 0/49 in port-channel 1 and status up, protocol up
port te0/50-52 status is up, protocol is down
with Cisco N5K, port e1/37 up, port e1/38-40 link not connected

- Try to use lacp mode on as in the example below for the involved interfaces (channel members) on the
nexus as in (for example) :
switch# configure terminal
switch(config)# interface fastethernet 0/1
switch(config-if)# channel-group 5 mode on

Replace interface names and channel group number accordingly and also have a look afterwards at
show ethernet channel summary

@marce1000

So I think problem lies with DELL. because, port-channel 1 on DELL have only member te 0/49

Why we change config Cisco N5K ?

can you brief describe the issue here
you have Server and Nexus and you connect it via PO
I ask because the title of your post is VS not To

>...Why we change config Cisco N5K ?
- Because foreign devices do not understand the Cisco LACP negotiation protocols then it becomes advisable to just use
channel-group x mode on (on the interfaces involved)
