Overview
Virtual LANs (VLANs) provide greater flexibility in the configuration and use of contexts and services.
They are configured as ―tags‖ on a per-port basis and allow more complex configurations to be implemented. The
VLAN tag allows a single physical port to be bound to multiple logical interfaces that can be configured in different
contexts. Therefore, each Ethernet port can be viewed as containing many logical ports when VLAN tags are employed.

Important:
VLANs are supported in conjunction with ports on the Ethernet 10/100 and 1000 line cards. (VLAN
tagging is not supported for SPIO ports.) The system supports the configuration of VLANs as follows:
Ethernet 1000 Line Card: 1024 VLANs per port.
Ethernet 10/100 Line Card: Maximum of 256 VLANs per port and a maximum of 1017 tagged VLANs and 8 untagged
VLANs per Line Card. (VLANs including tagged and/or untagged across all the ports of a single 10/100 Line Card can
not be more than 1025.)
