■ hybrid - Configures the port as a hybrid port that accepts and sends both tagged and un-

tagged frames.

The hybrid port works in conjuction with the Acceptable Frame Type:

 If the Acceptable Frame Type is set to All, the hybid port will accept and send both

tagged and untagged frames.

 If the Acceptable Frame Type is set to Tagged, the hybrid port will accept and send on-

ly the tagged frames.

 If the Acceptable Frame Type is set to untaggedAndPriorityTagged, the hybrid port

will accept and send the untagged and priority tagged traffic.

Please be aware of the fact that when the Acceptable Frame Type is set to All or Tagged,

you have to configure the PVID value in conjuction with the Acceptable Frame Type in or-

der for the selected port to carry traffic only for a specific VLAN.

Standards

■ IEEE 802.1Q – defines a system of VLAN tagging for Ethernet frames.

■ 802.1Q is the IEEE standard for tagging frames and supports up to 4096 VLANs. In 802.1Q,

the trunking device inserts a 4-byte tag into the original frame and recomputes the frame

check sequence (FCS) before the device sends the frame over the trunk link. At the receiving

end, the tag is removed and the frame is forwarded to the assigned VLAN.

Scaling Numbers

■ A maximum of 4066 series can be created.

Limitations

■ A maximum of 32 VLANs can be configured in PVRST mode.

Default Values

■ VLAN is enabled by default.

■ VLAN 1 is created by default.

■ All available ports are configured as member ports and untagged ports of the default VLAN

(VLAN 1).

■ The default operation mode for all ports: hybrid.

The static MAC address of a specific VLAN will be removed after deleting the VLAN.

The static ARP will be removed after deleting the VLAN interface.

VLAN 1 cannot be deleted using the no form of the command: no vlan <vlan-id>.
