VLAN Topologies and Design Considerations

Multiple VLANs with Tagging Adapters

© Copyright IBM Corp. 2011
Note the following when working with VLAN topologies:
• By default, the G8000 software is configured so that tagging is disabled on all
ports.
• By default, the G8000 software is configured so that all data ports are members
of VLAN 1.
• When using Spanning Tree, STG 2-128 may contain only one VLAN unless
Multiple Spanning-Tree Protocol (MSTP) mode is used. With MSTP mode, STG
1 to 32 can include multiple VLANs.
• All ports involved in both 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. For more information trunk groups, see
on page 107 and "Port Mirroring" on page
