VLAN Topologies and Design Considerations
By default, the G8124 software is configured so that tagging is disabled on all ports.
By default, the G8124 software is configured so that all data ports are members of VLAN 1.
By default, the BLADEOS software is configured so that the management ports (MGTA and
MGTB) are members of VLAN 4095 (the management VLAN).
MGTB) are members of VLAN 4095 (the management VLAN).
STG 128 is reserved for switch management.
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.

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:
following rules that determine how the configured VLAN reacts in any network topology:
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. For

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. For
