MDS UCS port channel configuration

[Charly__95]

Hello,

I want to configure a port channel with 4 interfaces between an MDS 9148S and a UCS 6248UP.

MDS 9148S version : 8.4(2)

UCS 6248UP version : 2.2(8i) - 5.2(3)N2(2.28i)

Here is the configuration:

MDS:

feature npiv
feature fport-channel-trunk

interface fc1/5
switchport mode F
switchport description Uplink_slrg2ucs2-fc1/29
switchport trunk mode off
port-license acquire
channel-group 210 force
no shutdown

interface fc1/6
switchport mode F
switchport trunk mode off
port-license acquire
channel-group 210 force
no shutdown

interface fc1/21
switchport mode F
switchport trunk mode off
port-license acquire
channel-group 210 force
no shutdown

interface fc1/22
switchport mode F
switchport trunk mode off
port-license acquire
channel-group 210 force
no shutdown

interface port-channel210
switchport mode F
switchport rate-mode dedicated
switchport trunk mode off

vsan database
vsan 210 interface port-channel 210

Port Channel with vsan 210

Thanks a lot for your help !

You will need to review logging logs to see why the links go error disabled.

Need to confirm SFPs in use,,, that fiber is not reversed (rx,tx), that these are FC SFPs and not ethernet SFPs (common mistake), etc, etc.

Also, make sure UCS side is also not in trunking (I think trunking is off by default).

Hello Kirk,

Thank you for your repply :)

SFP in use are :

MDS : DS-SFP-FC16G-SW SFP+

UCS : DS-SFP-FC8G-SW SFP+

Fiber is not reversed

SFP FC

Thanks a lot for your help

Precision, without port channel, the ports are UP.
As soon as I apply the port channel, they are in error.

Might be something like https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvk63036/?rfs=iqvred where the UCSM version you are on does not recognize the OUI of the port-channel of the MDS.

Are you using different speed FC SFPs on both end of fiber?
