Chapter 30. vMAN (PBN) 8800 Chassis Switch
1. If you are configuring a NETGEAR 8800, enable jumbo frames on the switch.
Note: Because the NETGEAR 8800 switch enables jumbo frames
switch-wide, you must enable jumbo frames before configuring vMANs on
NETGEAR systems.
2. Create a vMAN by entering the following command:
create vman <vman-name> {vr <vr_name>}
3. Assign a tag value to the vMAN by entering the following command:
configure vman <vman-name> tag <tag>
4. Add ports to the vMAN by entering the following command:
configure vman <vman-name> add ports [ all | <port_list> ] {untagged | tagged
| svid <svid>}
Specify tagged for network (switch-to-switch) vMAN ports, and specify untagged for
access (ingress and egress) vMAN ports.
Note: You must configure the vMAN egress port as untagged so that the
S-tag is stripped from the frame.
5. Configure additional vMAN options as described in Configuring vMAN Options on page 786..
6. To configure a VLAN to use a vMAN, configure the VLAN on the switch port at the other end
of the line leading to the vMAN access port.
Configuring vMAN Options
• Configuring the Ethertype for vMAN Ports on page 786
• Configuring IGMP Snooping on a vMAN on page 787
• Selecting the Tag Used for Egress Queue Selection on page 787
Note: You can use ACLs to configure some vMAN options. For more
information, see ACL Support on page 783.
Configuring the Ethertype for vMAN Ports
The ethertype is a component of VLAN and vMAN frames and is introduced in Secondary
Ethertype Support on page 783.
To configure the ethertype for vMAN (PBN) ports, do the following:
1. Configure the primary and secondary (if needed) vMAN ethertype values for the switch
using the following command:
