We integrated 2 24-port Ex2200 into a 48-port EX3400. IN the new EX3400 with the 4 ports (4,5,22,45) connected to VXRail, we cannot access some servers whose IP belongs to LAN, but under the old 2 ex2200, with ports 4,5,22 in one and port 21 in the other connected to VXRail, we were able to access those servers.
I matched all the port configs, but found that there is no vlan LAN, which is our default vlan, trunked through the old and new switches to the RXrails. I trunked LAN through 1 of the 5 ports in the new switch. Our whole network crashed after that point.
I rolled back my config to the one without LAN being trunked.
We still cannot access some servers on the VX Rails whose IP belongs to the LAN vlan. The firewall settings in our SRX340 remain the same.
Any ideas and suggestions?
