Cisco Error ‘%PHY-4-SFP_NOT_SUPPORTED’

Problem

This is another question I see getting asked a lot in forums!

You see something like the following;

[box]

000032: *Sep 28 09:35:32.507 UTC: %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi3/0/50 is not supported (PNL-3750-Stack)
000033: *Sep 28 09:35:32.507 UTC: %PM-4-ERR_DISABLE: gbic-invalid error detected  on Gi3/0/50, putting Gi3/0/50 in err-disable state (PNL-3750-Stack)

[/box]

The usual response is ‘Enable unsupported SFP’s’, and while that sometimes is the answer, it’s not always the answer!

 

Solution

1. Firstly Check the Modules and the Switches, Are you tying to plug a 10GB SFP+ into a slot that only supports SFP, (that includes plugging a twinax cable into an old switch!) In your ‘show run’ you should see TenGigabitEthernet (if your using SFP+ modules). Some switches with network modules list the same interface twice (once as 10GB interfaces and once at 1GB modules, I’ve blogged about that before see THIS ARTICLE, and to confuse things even further, the four interface versions, are grouped as two pairs with each pair consisting of one SFP slot and one SFP+ slot.)

2. Make sure your cable is NOT a CAB-SFP-50CM, (unless you are connecting a 3560 to ANOTHER 3560).

3. Are you using a 2960-S? If so you may need to update the IOS to use SFP+ (assuming your model supports SFP+ not all 2960-S models do).

4. Are you plugging into a Nexus switch with a 1GB connection? If so check the other end for the following error;

Description: Gi1/1/15: This port has been disabled because Non Compliant Gigabit Interface Converter (GBIC) connector detected.

If so, you may need to Manually set the speed on the 5K to 1000, (it wont auto-sense).

5. Is it a non-cisco branded SFP? If so it may still work, (but you will get no joy if you log a TAC call) with the following commands;

[box]

Petes-SW(config)#service internal
Petes-SW(config)#no errdisable detect cause gbic-invalid
Petes-SW(config)#service unsupported-transceiver

[/box]

If you are still in doubt check the Compatibility Matrix.

Problem

In a newly deployed switch, the MACSEC link refused to establish, when I consoled in I was greeted with this;

[box]

Dec 06 01:30:07.023: %ILET-1-DEVICE_AUTHENTICATION_FAIL: The FRULink SM Daughtercard inserted in this switch may not have been manufactured by Cisco or with Cisco's authorization. If your use of this product is the cause of a support issue, Cisco may deny operation of the product, support under your warranty or under a Cisco technical support program such as Smartnet. Please contact Cisco's Technical Assistance Center for more information.
Dec 06 01:30:07.023: %PLATFORM_SM10G-3-AUTHENTICATION: The FRULink 10G Service Module (C3KX-SM-10G) may not have been entirely manufactured by Cisco. Module is in pass-through mode.

-Traceback= 4E12E0z 250AA2Cz 26A1BE8z 269C198z

-Traceback= 4E12E0z 250AA2Cz 26A1BE8z 269C198z
[/box]

Solution

At first I assumed the C3KX-SM-10G was faulty, so I put it in another 3560-X switch and the problem moved, problem solved (or so I thought).

However I moved the service module in it’s entirety (SFP’s as well). After some more troubleshooting it turns out the service module was fine, the entire problem was caused by a faulty SFP (GLC-SX-MMD).
