Considerations for creating, editing, and deleting network sets

Creating or editing network sets

  • When you create a network, you can directly add the network to a network set.

  • When you create or modify a network set, you can designate a network for untagged packets. If you do not designate an untagged network, untagged packets are dropped on the profile connection associated with this network set. Untagged server traffic is either directed to the designated untagged network or is dropped.

    NOTE:

    Server traffic must be tagged with the VLAN ID of one of the Ethernet networks in the network set.

  • The server can send tagged traffic or untagged traffic simultaneously to the interconnect. The tagged traffic is sent on the designated network for untagged packets.

  • When you create or modify a network set, you define the maximum bandwidth and the preferred bandwidth for connections to that network set. A server profile can override the preferred bandwidth but not the maximum bandwidth.

  • A maximum number of 1000 Ethernet networks per logical interconnect are supported. A maximum of 162 Ethernet tagged networks per network set are supported.

  • Private VLAN networks can be added or removed only in pairs. Both primary and secondary networks must be added or removed together.

Deleting network sets

  • When a network is deleted, it is automatically deleted from all the network sets to which it belonged, unless the network set is a member of an uplink set.

  • When you delete a network set, the networks that belong to the network set are not affected. However, any server profiles with a connection to that network set are affected because their connections are defined to the network set and not to the individual networks. Because the network set is no longer available, the network traffic to and from that server through that connection is stopped. When you delete a network set, any server profile connection to that specified network set is disconnected.

  • When deleting networks in the network set, if all in-use networks are removed from the network set, all assigned profiles using this network set are in error and the server profile connections lose connectivity. To avoid connectivity loss, either leave at least one network in the network set or disassociate the network set from all server profiles.

  • When deleting networks from a network set, if all the networks are removed from a network set, a removal action requires a confirmation with a warning that traffic will no longer pass. When a network set becomes empty, Virtual Connection modules will not pass traffic for those server profile connections.
