Hello,

 

Management traffic

 

1.1 (out-of-band OOB)

If you are using the management interface (out-of-band) for management traffic, you will have a connection/ cable going out of the management port of the S4112 switch to the router that is the default gateway for mgmt traffic, in this example 192.168.100.1 ip will be located on the router.

 

! Configure the management interface

configure terminal

interface mgmt1/1/1

no shutdown

ip address 192.168.100.10/24

exit

 

! Set the default gateway for management traffic

management route 0.0.0.0/0 192.168.100.1

 

! Save the configuration

exit

write memory

 

 

1.2 (in-band) If you want to manage the switch in-band, then you will have a vlan with an ip address, and use that IP when you SSH to the switch

 

 

2. Data traffic.

If you have an L2 switch, you do not need to configure a default gateway on it for data traffic. You will have to configure the Default Gateway on the hosts/servers, to use the Aruba as Default Gateway. The IP address will be physically located on the Aruba, and it has to be in the same subnet as what is configured on the host. You should be able to see the mac address of the host and mac address of Aruba port learned in the same vlan on the switch. A packet sent from the host will directly go layer2 to Aruba in the same vlan/subnet.
