VLANs and Port Vlan ID Numbers

Alteon OS Application Guide

VLAN Numbers

Alteon OS supports up to 1024 VLANs per switch. Even though the maximum number of VLANs supported at any given time is 1024, each can be identified with any number between 1 and 4095. VLAN 1 is the default VLAN for the external ports and the internal blade ports. VLAN 4095 is reserved for use by the internal management ports (MGT1 and MGT2). VLAN 4094 is reserved for use by the external management port (EXT7).

PVID Numbers

Each port in the switch has a configurable default VLAN number, known as its PVID. By default, the PVID for all non-management ports is set to 1, which correlates to the default VLAN ID. The PVID for each port can be configured to any VLAN number between 1 and 4094.
