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.
•The following gigabit MDA restriction applies for VLAN configurations: tagging is restricted on secondary VLANS to either all tagged or all untagged.
