A Virtual Local Area Network (VLAN) is an L2 segment of the network which defines a broad-
cast domain and is identified by a tag added to all Ethernet frames running within the domain.
This tag is called a VLAN ID (VID) and
can take a value of 1-4094.
Each port can have a switch mode of either:
• Access – Access port is a port connected to a
host. It can accept only untagged frames,
and assigns them a default configured VLAN (Port VLAN ID). On egress, traffic sent
from the access port is untagged.
• Access-dcb – This mode is Mellanox specific that
receives ingress untagged traffic but
sends egress priority tag (VLAN ID = 0)
• Hybrid – Hybrid port is a port connected to either switches or hosts. It can receive both
tagg
ed and untagged frames and assigns untagged frames a default configured VLAN
(Port VLAN ID). It receives tagged frames with VLANs of which the port is a member
(these VLANs’ names are allowed). On egress, traffic of allowed VLANs sent from the
Hybrid port is sent tagged, while traffic sent with PVID is untagged.
• Trunk – Trunk port is a port connecting 2 switches. It accepts only tagged
frames with
VLANs of which the port is a member. On egress, traffic sent from the Trunk port is
tagged. By default, a Trunk port is, automatically, a member on all current VLANs.
5.3.1 Configuring Access Mode and Assigning Port VLAN ID (PVID)
 To configure Access mode and assign PVID to interfaces:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Create a VLAN. Run:
Step 4. Change back to config mode. Run:
Step 5. Enter the interface context. Run:
Step 6. From within the interface context, configure the interface mode to Access. Run:
Step 7. From within the interface context, configure the Access VLAN membership. Run:
Step 8. Change back to config mode. Run:
switch > enable
switch # configure terminal
switch (config) # vlan 6
switch (config vlan 6) #
switch (config vlan 6) # exit
switch (config) #
switch (config) # interface ethernet 1/36
switch (config interface ethernet 1/36) #
switch (config interface ethernet 1/36) # switchport mode access
switch (config interface ethernet 1/36) #
switch (config interface ethernet 1/36) # switchport access vlan 6
switch (config interface ethernet 1/36) #
