VLAN 1 Communication down between SW5900 and 5930

[augoudi]

Hi!

I first activated interface Vlan 1 with ip adress so I can have a web management interface in both 5900 and 5930 switches - Great i finally succeded having web interface on 192.168.1.1 and 192.168.1.2 respectively to the switches.

I suddenly don't know what happen, I am not able to ping 5900 from 5930 neither 5930 from 5900 though it was working very well using vlan1. Both switches are connected though:

- 5900 : FGE1/0/53 & FGE1/0/53 with another BAGG port

- 5930 : FGE1/0/1 & FGE2/0/1 with another BAGG port

Note 5930 is in reality 2 x 5930 binded. 

Could someone help me please to identify where the issue is ?

Start with providing us outputs of

display link-aggregation verbose

CLI command, executed on your HPE 5930 IRF (your 5930 pair) and on the HPE 5900 Switch.

Also details about their respective ip assignments on VLAN 1 (default VLAN) would help.
