VLAN Configuration Rules

VLANs operate according to specific configuration rules. When creating VLANs, consider the following rules that determine how the configured VLAN reacts in any network topology:

•All ports that are involved in port mirroring must have memberships in the same VLANs. If a port is configured for port mirroring, the port’s VLAN membership cannot be changed.

•If a port is a trunk group member, all trunk members are added or deleted from the VLAN.

•All ports involved in trunking and port mirroring must have the same VLAN configuration. If a port is on a trunk with a mirroring port, the VLAN configuration cannot be changed.

•VLANs are not dependent on Rate Limiting settings.

•If a port is an IGMP member on any VLAN, and is removed from a VLAN, the port’s IGMP membership is also removed.

•If a port is added to a different VLAN, and it is already configured as a static router port, the port is configured as an IGMP member on that specific VLAN.

For more information about configuring VLANs, see “VLAN Configuration Menu” on page 3-22.
