Segmented VRF scaling a bit misleading

[Yoann_Jonard]

Hello,

The release notes for FE9.4 are a bit misleading, and I have already received the same question twice from my customers.

The RN takes as an example a switch with 2 manually configured VRF, one being segmented, and displays the output of the show ip vrf command which shows 4 VRF (GRT, mgmt + the 2 created above).

Then it compares this display with the result of a show khi resource-scaling, which displays the number of L3VSN resources consumed, which is 4 (3 for the segmented VRF, 1 for the non-segmented VRF).

You see where the confusion is for the customers : show ip vrf = 4, show khi resource-scaling = 4...

I would suggest as an example, configuring 3 VRF, 2 being segmented. This would lead to :

1. "show ip vrf" = 5
2. "show khi resource-scaling" = 7

The result numbers would be different, eliminating the confusion.

Output below so you just have to copy paste :

I understand they do not show the same thing, it's just that for customers (maybe not entirely familiars with Extreme's concepts) they got confused because of this very example (4 being displayed in both commands).

It does not require a lot of work to lift any ambiguity by providing another example IMHO.

Hi Yoann

Yes but, those two commands are not showing the same thing. The khi command show the number of hardware resources used to make VRF happen. In the first show ip vrf command, the MgmtRouter is fictitious these days, and the GlobalRouter (GRT) does not consume those resources (at least the khi command does not count it).
Maybe you should try the new "show ip vrf detail" command; that should make things clearer.
