Alteon OS Application Guide

VLAN Topologies and Design Considerations

„By default, the Alteon OS software is configured so that tagging is disabled on all external ports and all internal ports.

„By default, the Alteon OS software is configured so that all internal ports are members of VLAN 1.

„By default, the Alteon OS software is configured so that the management ports (MGT1 and MGT2) are members of the management VLAN 4095.

„By default, the Alteon OS software is configured so that the external management port (EXT7) is a member of VLAN 4094.

„If configuring Spanning Tree Groups (STG), note that Spanning Tree Groups 2-128 may contain only one VLAN.

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 involved in trunking and port mirroring must have the same VLAN configura- tion. If a port is on a trunk with a mirroring port, the VLAN configuration cannot be changed. For more information trunk groups, see “Port Trunking Example” on page 97.

„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 more information on configuring port mirroring, see “Monitoring Ports” on page 246.
