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-if)#
switchport mode access
(config-if)#
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. Note that VLAN 5 is omitted from
the list of e gress-tagged VLANs.
(config)#
interface ethernet 1/1
(config-if)#
switchport mode hybrid
(config-if)#
switchport hybrid native vlan 5
(config-if)#
switchport hybrid allowed vlan 1-10
(config-if)#
switchport hybrid egress-tagged vlan 1,2,3,4,6,7,8,9,10
(config-if)#
show interface eth1/1 switchport
(config-if)#
show running-config interface ethernet1/1
Switchport Trunk Mode
Trunk mode is also used when an interface needs to carry multiple VLANs. Trunk mode configuration is less explicit
than Hybrid mode. In the following configuration example, the Scale Computing appliance is being managed on
VLAN 5.
(config)#
interface ethernet 1/1
(config-if)#
switchport mode trunk
(config-if)#
switchport trunk allowed vlan all
(config-if)#
switchport trunk native vlan 5
(config-if)#
show interface eth1/1 switchport
(config-if)#
show running-config interface ethernet1/1
