Hi,This command has been. Tks Marcio. Joseph W. I believe this is a global command, not an interface command. Re: Command service unsupported-transceiver.
Yes, it's undocumented as it's one of Cisco's "hidden" commands. What it did on earlier IOSs, it allowed non-Cisco transceivers to be used. Without it, the IOS would disable the port if a non-Cisco transceiver was plugged into the port. BTW, enabling non-Cisco transceivers doesn't guarantee they will work. Further, if you have problems with non-Cisco transceivers, Cisco TAC won't help resolve such problems until the non-Cisco transceiver is replaced with one of theirs.The Previously, the switches were simply blocking the use of 3th party transceivers.
With this new command, the admin can override this behavior. This does not mean that these 3th party transceivers are supported, it only means that the port is no longer disabled when an unsupported transceiver is connected.
The switch will still generate daily log messages to warn the admin that this feature has been enables. I just tried a running KB. I believe the would be added as well, but that may come in a later release. Hi, it seems the feature is gone in I booted a to KB. I booted back to KB.

So the command is still available, just hidden. Hi, With the I known, but when one of my two F Dis you find a way to waork around this?
I have the same issue actually: unsupported transceiver not working in VSF. I have tried all the below IOS versions, still non of them worked. You are commenting using your WordPress.

X Arista Networks, Inc.This article discusses a common problem and mitigation techniques with certain supported GBICs or SFPs optical transceiver modules on a Catalyst switch. Please keep in mind the following points before considering this as a hardware issue with the SFP, sub-module CNM or backplane.
Verify compatibility between the SFP and the switch, sub-module and software version. You can refer these compatibility matrix documents. Some SPFs need configuration and actions to be able to work in a Catalyst switch mostly when they are manufactured by third-party.

Our switches are in the same rack as the servers so we just use DAC's, some Arista, some Cisco, no issues with Cisco, or Mellanox cards. Thanks for the information. I will post my findings when I receive the switch. Jerry Renwick Active Member. Joined: Aug 7, Messages: Likes Received: Jerry RenwickJun 8, Foray Member. Joined: May 22, Messages: 45 Likes Received: We already covered this in a previous thread, there exists a command "service unsupported-transceiver" to allow unsupported transceivers.
It requires a specific input but its not bound to any serial or hardware, just the nonce and code, which should be able to be found with a simple search.
How can I know that they will work in the Cisco switch I have? I don't have any direct experience with arista SFP and cisco switches but the SFP interface is standardized such that it is supposed to work. Now, if it works or doesn't work, it won't be supported.
It won't void your warranty or anything, but if you have weird problems related to that link, I wouldn't advertise that you're using a non-cisco branded module. On the Cisco device you must enter this command to enable use of 3rd party optics:. Some routers and switches will refuse to use a Non-cisco SFP eeprom checkwhile some others will need the following commands to make it work and some others just work :. Some Finisar's are known to work, while some Zycko's works even without "service unsupported-transceiver".
You can also browse through Cisco-nsp mailing-list archive to find more informations about compatible or not vendors. I keep running into this more and more. Rather than swap out 2 different brands of SFP I would just go for a low cost compatible. Finisar SFP's are usually a generic code to work in 'most' devices.
You need to get SFP's specific to the device to be sure. Please see this document regarding the compatibility of SFP's and also a FAQ I put together in an attempt to straighten out some of the confusion on this topic. Sign up to join this community.

Good answer, I typically keep one legitimate supported SFP on hand I can swap in, in case support has a gripe about the physical link. On the Cisco device you must enter this command to enable use of 3rd party optics: service unsupported-transceiver. HampusLi HampusLi 3, 12 12 silver badges 14 14 bronze badges.

Hi all, Is there a way for unlocking off-brand transceivers usage on Arista switches? I've got an Arista QX switch with 4. Then it has been found out that Arista switches seem to not have possibility to unlock off-brand xcievers usage by some service command or so.
But despite of xceivers are detected correctly, links aren't coming up they are in notconnect state. If anyone possibly have does have a sacred knowledge of bringing off-branded transceivers to life on Arista switches, your help'd be very appreciated. Yes, email support and ask for the unlock code, they will make you agree that you know that 3rd party optics may explode the switch and it's not their fault.
Let me know if you want samples. We can ship today. Hi Tim, Thanks for your expressive answer. Exactly this, get your unlock key that is tied to your company and you are off to the races, bake it into your standard config. Hi all, If somebody is following my epic adventure of getting uqualified SFP to work on Aristas, here is the unhappy end of it.
I've written to Arista support and got the following dialogue: Support guy: Hi, Thank you for contacting Arista Support. Could you please provide the "show version" output from this switch? Unfortunately, we are unable to activate your 3rd party components. To ensure ongoing quality, Arista devices are designed to support only properly qualified transceivers. Please let me know if you have any other questions. Me: I do not understand, But there is a command which allows using non-Arista transceivers.
Why have you implemented it but don't provide an access key to your customers when they ask for it? If it is required to sign some papers which declare that I am aware of all the risks and losing my warranty - I agree with that, lets do it. Any way what are the conditions to receive that access key? Support guy: I'm afraid that there is nothing I'm able to do regarding this situation. If you have any other questions regarding enabling 3rd party options in Arista switches, I suggest to contact your local account team or sales for further discussion on this matter.
I'm writing this post to make somebody who considers buying their switches be aware of what they'd get. Just buy Juniper instead. And I was about to jump on to the Arista train Hello all, At my actual job, some colleagues bought Arista switchs very recently.
They asked the question about 3rd party transceivers and their SE told them exactly what has been said before : "we do accept 3rd party transceivers but we don't support them. If you still want to use them willingly, you'll have to sign a discharge paper and we'll provide you with a key to activate on your equipement". That's Arista's official policy regarding 3rd party transceivers.
Your AM team will gladly unlock this for you. This is probably just a procedural issue with Arista TAC not knowing the secret sauce. Same here, i was considering Arista, because they are quite cost effective,feature rich, interesting hardware for developing some custom solutions.Arista Networks Demonstrating CloudEOS™
