Port Configuration
By default, all ports are in access mode for VLAN 1. If you are not utilizing VLANs in your environment, you will not
need to configure the VLAN settings for the switch ports further. We recommend isolating backplane ports for Scale
Computing equipment to a VLAN other than 1 using access mode.
Switchport Access Mode
Access mode allows only one VLAN to be configured for a switch port. Use this mode when connecting an end
device that is unaware of VLANs, such as the Scale Computing node backplane ports.
(config)# interface ethernet 1/1
(config interface ethernet 1/1)# switchport mode access
(config interface ethernet 1/1)# switchport access vlan 10
Switchport Hybrid Mode
Hybrid mode is used when an interface needs to carry multiple VLANs, such as the Scale Computing LAN ports. If
your VMs need access to specific VLANs other than what the Scale Computing node itself resides upon, you will
need to tag those VLANs. In this example, the Scale Computing appliance is being managed on VLAN 5. The
management interface is unaware of VLANs and thus needs to be untagged traffic. Any additional VLANs need to be
added to the list of allowed-vlan.
(config)# interface ethernet 1/1
(config interface ethernet 1/1)# switchport mode hybrid
(config interface ethernet 1/1)# switchport access vlan 5
(config interface ethernet 1/1)# switchport hybrid allowed-vlan add 10
Configure Spanning Tree
Ensure spanning tree is enabled:
(config)# spanning-tree
(config)# spanning-tree mode rpvst
NOTE
The number of VLANs supported by RPVST is 128.
Set ports connected to Scale Computing equipment to edge mode:
(config)# interface ethernet 1/1
(config interface ethernet 1/1)# spanning-tree port type edge
