Dynamic Auto Fabric

[narayanan]

What is Dynamic Auto Fabric creation ?

how it works ?

I think it is explained in the network guide, so read that if you want a definate answer.
(In the NT Guide chapter 14)

Short: it is a Alcatel way to configure a bunch of detected features on 6900, including spb, lacp, mvrp aso.

In my experiences (before 7.3.4) it was useless for every scenario i installed 6900s, as my customers did not use mvrp or spb.
So the only thing i did was:

auto-fabric admin-state disable remove-global-config
mvrp disable
spb isis admin-state disable
no spb bvlan 4000-4015
spantree mode per-vlan

and afterwards configure as i like.

in 7.3.4 the you have a new feature auto-configuration. More infos in RN for it.
after start you will see at a switch without boot.cfg/vcboot.cfg/vcsetup.cfg the following question at the console:

Code: Select all

Do you want to disable auto-configurations on this switch [Y/N]?

if you do nothing than it will take "No". Now the switch creates a demo license advanced routing for 45 days and the switch starts in VC mode. If you have connected (or do it later) one or more of the last 5 ports (in auto-vfl) with an other chasssis in this this mode (also last 5 ports in auto-vfl), than it will create a vfl to this other chassis....

I have tested this and it works fine.
You have to deside by yourself if you would like to use the other features (see post from devnull). You can disable this like described.

How to configure IP. and check whether IP is formed to autofabric.
Autofabric send message to IP.. but IP configurations are not found.
do we need to configure any additional configuration for IP like route, VRF, VRRP, ip load isis

please help

[devnull]

IP is not chossen in autofabric but RCL should be active (Remote configuration load) -> have a dhcp server with correct options can make the switch to download a specific config.

-> I have no pratical experiences as my setups are too small, so that i have no use in creating a overhead of dhcp/tftp server for that things.
If you are pushing out loads of 6900 you may experiment with this.

autofabric makes some setup for you but not all. So ip interfaces (if not dhcp) static routes must be provided by you (either cli or by a preconfigured configuration.

Thank you,

I also have a small setup of 2 or 3 DUT.

Can you share any sample configurations using VLAN

[devnull]

Please read the manual. This basic configuration must be maintained by you hence you should get familar with this.

vlan X name
ip interface NAME address X/y vlan y
ip static-route
vlan x members port X/Y (un)tagged
