Backplane sub-tab

Backplane settings configure the switch interfaces directly exposed to the Nodegrid OS. For the Nodegrid OS to communicate with any existing switch ports, at least one of the backplane interfaces must be part of the specific VLAN. The backplane settings display the current VLAN associations. If the switch backplane port is added as a tagged member of a VLAN, a corresponding VLAN interface needs to be created in Nodegrid OS to receive the packets from the switch. 

The Backplane settings also configure the switch ports connected to the compute expansion card. The compute card has two 10G network interfaces that are connected to the built-in switch in NSR, and to the neighbor slot network expansion card in NSR Lite. The switch ports connected to the compute card appear as slot<X>-0 and slot<X>-1, where X is the slot number where the compute card is inserted.

Edit Backplane Settings

1. Go to Network :: Switch :: Backplane.
2. Make changes, as needed:
   1. Port VLAN ID: VLAN to be assigned to the untagged ingress packets coming from Nodegrid OS
   2. Jumbo Frame: If enabled, the Jumbo Frame configured under Global will be
   3. DHCP Snooping: Trusted means this is a trusted port so DHCP Server Responses will be accepted; Untrusted means the DHCP Server responses will be dropped. This configuration is applicable only if DHCP Snooping is enabled
      under Global, and DHCP Snooping is enabled in the VLANs in the DHCP Snooping
      sub-tab.
