Routing between vlans on EX4200 [ Edited ]

[xxxmen]

Hi everyone, I face a strange issue on my EX4200, I have 3 vlans + vlan 20 (server): 172.16.20.1/24 + vlan 100 (mgmt) 172.16.100.1/24 + vlan 30 (wireless) 172.16.30.1/24 When I am in vlan 20 or vlan 100, I can only ping the vlan interface (i.e. 172.16.20.1 or 172.16.100.1) not the devices inside the other vlans. For example: I am in vlan 20, I can ping 172.16.20.1, 172.16.100.1 but i can not ping 172.16.100.2 (server inside vlan 100). This 172.16.100.2 can be pinged if I am in vlan 100. I have attached my configuration file. Can anyone help me out with this? Thanks.

Hi,

your vlan 100's subnet seems to overlap with with the out of band management network. Try to remove the patchcable from the the management port and see if this is the problem.

Hi Screenie,

Problem solved, that is the cable from the managemnet port.

Thanks for your help.
