Description

Internal Networks

List of assigned internal Ethernet networks that allow server to server communication within the same logical enclosure without a top-of-rack switch. The VLAN ID is also shown for tagged networks.

Internal networks enable you to explicitly designate which logical interconnect and network to use for server-to-sever communication. For example, to have all servers communicating over network net_100, you can designate net_100 as an internal network for a logical interconnect. The server profile ensures that every server connected to net_100 uses the downlinks connected to the interconnect with net_100 on it.

If there are more than 50 networks, a link is displayed to the Networks screen, filtered to the list of networks that are in the set. Internal networks can contain tunnel and untagged networks, so instead of a VLAN ID, it will display tunnel or untagged as a label.

Duplicate VLAN IDs are allowed on internal networks because the external VLAN ID is not used to route traffic within the Virtual Connect stacking domain.

Ethernet networks are automatically moved from uplink sets to internal networks when removed from an uplink set on the logical interconnect to avoid an outage. However, if you remove an Ethernet network from an uplink set in a logical interconnect group, the network does not get moved automatically to the internal networks.
