VLAN Configuration
VLANs are commonly used to split up groups of network users into manageable broadcast domains to create logical segmentation of work groups, and to enforce security policies among logical segments. This menu is used to configure VLAN attributes, change the status of the VLAN, delete the VLAN, and change the port membership of the VLAN.
By default, the VLAN menu option is disabled except VLAN 1, which is always enabled.

VLAN Configuration Menu Options (/cfg/l2/vlan) 
Command Syntax and Usage
name
 
Assigns a name to the VLAN or changes the existing name.
Default: The first VLAN name
ip6nd
 
Displays the IPv6 Neighbor Discovery menu This menu is used to enable or disable sending IPv6 Router Advertisement packets from this interface. To view this menu, see /cfg/l2/vlan/ip6nd IPv6 Neighbor Discovery Menu.
stg <Spanning Tree Group index (1-16)>
 
Assigns a VLAN to a spanning tree group.
cont <BW Contract number, (1-1024)>
 
Sets the Bandwidth Management contract for this VLAN.
Default: 1024
nonip <BW Contract number, 1-1024>
 
Sets the Bandwidth Management contract for non-IP traffic for this VLAN.
Default: 1024
lla d|e
 
Specifies whether to enable automatic static IPv6 link-local address generation.
*enable — A static IPv6 link-local address is generated automatically.
*disable — A static IPv6 link-local address is not generated automatically. To manually configure a static IPv6 link-local address for the VLAN, use the lladdr command.
Default: disable
lladdr <IP6 address (eg, FE80:0:0:0:0:0:abcd:12 or FE80::abcd:12 or any).
 
Specifies a static IPv6 link-local address for the VLAN. To use this command, automatic generation of a link-local address must be disabled (see the lla command).
add <port number>
 
Adds ports or trunk groups to the VLAN membership.
rem <port number>
 
Removes ports or trunk groups from this VLAN.
def <list of port numbers>
 
Defines which ports are members of this VLAN. Every port must be a member of at least one VLAN.
Default: 1 – 28 for VLAN 1
jumbo disable|enable
 
Enables or disables jumbo frame support on this VLAN. You need to reset Alteon using the /boot/reset command to enable jumbo frames.
Jumbo Frames are not supported in this version.
learn disable|enable
 
Enables or disables source MAC address learning on this VLAN. This is not relevant for vADC Administrator.
shared disable|enable
 
Specifies whether to enable Alteon to share this VLAN between vADCs. This command only appears in the vADC Administrator environment in ADC-VX mode.
When sharing is enabled, Alteon does not participate in Layer 2 switching. When a port is shared among vADCs, Alteon drops packets with a destination MAC address that does not match the MAC address of any of the vADCs, otherwise Alteon looks for a matching VLAN and/or port.
Default: disable
For more information, see vADC Creation Dialog.
ena
 
Enables this VLAN.
dis
 
Disables this VLAN without removing it from the configuration.
del
 
Deletes this VLAN.
cur
 
Displays the current VLAN configuration.
Note: All ports must belong to at least one VLAN. Any port which is removed from a VLAN and which is not a member of any other VLAN is automatically added to default VLAN 1. You cannot remove a port from VLAN 1 if the port has no membership in any other VLAN. Also, you cannot add a port to more than one VLAN unless the port has VLAN tagging turned on (see the tag command in /cfg/port <port number> Port Configuration Menu).
