SFP-10G-AOC10M does not detected by WS-C2960X-48FPD-L

[loksa_blr]

Hello.

I've got two SFP-10G-AOC10M optical transceiver modules, and want to use them as uplinks for Catalyst 2960-x switch stack to 4500-X.

When I insert SFP modules to Cat2960-X I get next messages in log:

%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi4/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi4/0/50, putting Gi4/0/50 in err-disable state
%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi5/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi5/0/50, putting Gi5/0/50 in err-disable state

Looks like switches detected this modules as 1G not 10G.

According to Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix these modules should be supported by Cat 2960-X with 15.0(2)EX IOS release. I had 15.0(2)EX5 release and even upgraded to 15.0(2a)EX5.

I've inserted two other modules in this ports and they are detecting correctly:

Any ideas?

Hi,

I have confused by the output you posted.

The 10Gig uplink ports start with te1/0/1 for switch 1 in the stack and te2/0/1 for switch 2 in the stack and te3/0/1 for switch 3.  5/0/49 and 5/0/50 interfaces are 1Gig and not 10.

Can you clarify?

Also, what is the switch mode number?

Hello.

That is the problem. Switch has 48 Gigabit ports and they appear as Gi4/0/1-Gi4/0/48. And two uplink ports for SFP or SFP+ modules. 10Gig uplinks module should be detected as Te4/0/1 and Te4/0/2. Gigabit will be detected as Gi4/0/49 and Gi4/0/50.

Once I insert SFP-10G-AOC10M to the switch uplink port I get messages in logs:

%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi4/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi4/0/50, putting Gi4/0/50 in err-disable state

So instead to be detected as Te4/0/2 it is detected as Gi4/0/50.

I've tried to insert into uplink ports two other modules: GLC-T (1gig) and SFP-H10GB-CU3M. And they are detected correctly(see two last outputs in first post).

Hi,

What version of IOS are you running on the 2960-X?

[loksa_blr]

Switches were shipped with 15.0(2)EX5 release. I've upgraded to 15.0(2a)EX5 (this was shown as suggested for 2960-X).

Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix declares  that SFP-10G-AOC10M modules should be supported by Cat 2960-X starting from 15.0(2)EX IOS release.

I've upgraded switch software to 15.2(3)E1 release. Now SFP-10G-AOC10M modules detected correctly.

I'm having a similar issue.

 I have two 2960S and want to connect them using Fiber.

I've installed the transceiver on both on the switches but the link doesn't come up. is there anything else that I should be doing to bring the links up ?

the SFPS are GLC-SX-MMD
