Dear Cisco - some suggestions

Unlike Webex, which has a dedicated site where users can make suggestions to improve the product, ACI has NO such public facility (that I know of - happy to be corrected - and yes I've already submitted these via the Feedback option in ACI, but I have no idea if they are even ever read). So let me make some suggestions here.

Suggestion 1: Feedback Site

A site where users could make suggestions and vote on proposed suggestions would be useful

Suggestion 2: L3Outs and FEXs

There is no support for L3Out on a FEX.

BUT if you have a FEX, and you are configuring an L3Out, and choosing an interface from the drop-down list, all the FEX interfaces are listed - AND EVEN MORE ANNOYING - they are listed first.

SUGGESTION: Don't list the FEX interfaces in the interface drop-down when configuring L3Outs

Suggestion 3: BGP L3Outs and MTU

When creating an L3Out for BGP, at the interface configuration, there is an option to specify the MTU.

This has no meaning in relation to BGP. BGP uses TCP.  And setting it (I believe) has no effect on anything.

SUGGESTION: Remove the MTU configuration from the interface configuration stage of the L3Out wizard wen configuring BGP

Hi Chris,

 

I'll be playing the devil's advocate for a moment here

The suggestion 2 and 3 sounds like cosmetic bugs, which I agree, can confuse the users, especially the s2, but still it remains as cosmetic bugs. Now these are usually filtered through TAC, to avoid dumping all the not-super-important defects on developers, so they could focus on higher priority bugs. For example, S2 will be a good candidate for a P4 bug, s3 - I can live with it, it doesn't bother me.

However, a feedback website it's definitely a GREAT IDEA, where suggestions can be submitted and users can vote and Cisco ACI BU/TME team to monitor that website. I believe you can do it in the CCP section of cisco community, however it doesn't look to be monitored by someone from a technical team - I suggested a dark theme for the GUI, which let's be honest - will be a great add-on for day-to-day operations.

Thanks for the input Chris.  I'll pass the feedback along through the team here.  Some comments.  The Feedback that is submitted via the UI directly is reviewed regularly.  We've used this facility very well on DNAC and other platform solutions to great impact.  As with any feedback its a balancing act of priorities.  There are limited dev resources and cosmetic enhancements are at the bottom of the food chain.  I do like the public ranking of enhancement requests though, let me see what I can come up with for this - stay tuned.

The UI filter of FEX interfaces appearing in an L3Out selection, is simply the same interface-lookup call used everywhere else in the system.  They'd have to branch and customize that piece of code just to appease the few customers a) deploying FEXs and b) bothered by it.  Certainly not impossible, but I haven't heard or seen any other customer request this either. Even with the weight of your feedback, its a tough solo-sell

Same applies to BGP L3Outs.  It's just re-using common UI panels.  They'd rather include an used-non-mandatory field in the panel, rather than customize it for each protocol.

@Sergiu.Daniluk and @Robert Burns ,

Thanks for contributing. I agree the FEX thing is only cosmetic, and given that the number of people that this bothers is small it is probably low priority.

The Interface List

But I can't accept that it would require customised code to at least SORT the list so that the FEX interfaces appear AFTER the regular interfaces, because selecting an interface from the dropdown when deploying a static port has the FEX interfaces listed AFTER the regular interfaces. Clearly someone actually customised the code for the L3Outs to put FEX interfaces first, or passed different parameters to have it sorted the way it is.

The MTU Field

The MTU field appearing when it is not required is more serious. ACI is confusing enough, especially L3Outs. I have long believed that not NEARLY enough though went into the user interface for the APIC UI, almost as if the designers set out to confuse users with MANY instances of inconsistent naming*.

So the point being that there is NO excuse to have a field showing that, if filled in, is NOT applied to the configuration.  At the VERY LEAST, if a standard template MUST be used, the template could show a message such as Not used in BGP L3Outs appearing below the field, much the same as the Leave empty to not configure any loopback message appears on the same dialogue.

I'll leave it there, and hope SOME changes are made.

* RedNectar's Rant

Don't get me started on talking about inconsistent naming, this was the cause of many wasted hours for me when I first started and it still smarts to see a list of associated "Interface Selector Profiles" showing for a Leaf Profile, when no such object called "Interface Selector Profile" exists. There are "Leaf Interface Profiles" (which is what is ACTUALLY listed) and "Interface Selectors". But NO SUCH OBJECT as an "Interface Selector Profile".  But you'd have to pay me to actually go and find all of the inconsistencies in ACI! (If you know where to look, I've already documented many of them publicly)

+1 for inconsistent naming

@RedNectar @Sergiu.Daniluk 

I had a chat with our UI Dev team.  We should be able to fix both the MTU & FEX Interface issues for L3 Outs - I'll provide the CDET IDs so you can track these on your end once finalized.

For the naming inconsistencies, can you guys do me a favor and start a new thread to track/list all inconsistencies you can think of/find?  I'll take this back and see what can be done to clean it up. 

Your feedback doesn't fall on deaf ears.  We'll continue to improve as you continue to provide feedback!

Thanks,

Robert
