switches 3850 port-channel failed

[marzi]

Hi everyone

I have a pair of stacked 3850 switches.

The stacked switches have two uplinks (Tengig1 /1/1 and Ten2 /1/4) in port-channel.

Port Te1 /1/1 fails to activate in port-channel.

The release used is cat3k_caa-universalk9.16.12.03a.SPA.bin
(install mode)

below the show interface Ten1 /1/1

I've noted Hardware is not present but how I can solve it ?

Thanks in advance for any help

Is this a cisco SFP, what is speed and SFP model information can provide here.

Hi Balaji

Here are the information required :

Name : Gi1/1/1
Administrative Speed: 1000
Administrative Duplex: full
Administrative Auto-MDIX: on
Administrative Power Inline: N/A
Operational Speed: 1000
Operational Duplex: full
Operational Auto-MDIX: on
Media Type: 1000BaseSX SFP

Name : Te2/1/4
Administrative Speed: 1000
Administrative Duplex: full
Administrative Auto-MDIX: on
Administrative Power Inline: N/A
Operational Speed: 1000
Operational Duplex: full
Operational Auto-MDIX: on
Media Type: 1000BaseSX SFP

Thank's

i am confused with the information, you mentioned one port ten 1/1/1 and ten 2/1/4

but as per your recent post, you provided gi 1/1/1 and ten 2/1/4

can you post

show switch

show interface status

is the SFP you using on uplink cisco brand or any other brand? what is the model of SFP?

Hi

swccopn0b2#show switch
Switch/Stack Mac Address : cc98.916b.9500 - Local Mac Address

show interfaces status

Port Name Status Vlan Duplex Speed Type
Gi1/1/1 connected trunk full 1000 1000BaseSX SFP

Te2/1/4 sw-ccocore Te2/0/2 connected trunk full 1000 1000BaseSX SFP

Now I've not brand and sfp model, but as soon as possible I' complete these information.

Anyway I see that there is something wrong in fact interface 1/1/1 seems a Giga and not a Tengiga

Thank's

Hi all

I solved the problem.

looking better the uplink module (Uplink Module 1", DESCR: "2x1G 2x10G Uplink Module"),

I saw that there are four ports for each switch :

Gig1/1/1, Gig1/1/2, Gig/Ten1/1/3, Gig/Ten1/1/4

Gig2/1/1, Gig2/1/2, Gig/Ten2/1/3, Gig/Ten2/1/4

It seems that it is not possible to form a port-channel, mixing port Gig and Ten/Gig.

For example I did a port-channel with Gig1/1/1 and Gig2/1/1 or Gig/Ten1/1/4 or Gig/Ten2/1/4.

That's my experience

Anyway thank's at all and have a nice day
