Service Manual

Virtual LAN (VLAN) Commands
The following commands configure and monitor virtual LANs (VLANs). VLANs are a virtual interface and use many of the same commands
as physical interfaces.
You can configure an IP address and Layer 3 protocols on a VLAN called Inter-VLAN routing. FTP, TFTP, ACLs and SNMP are not
supported on a VLAN.
Occasionally, while sending broadcast traffic over multiple Layer 3 VLANs, the VRRP state of a VLAN interface may continually switch
between Master and Backup.
NOTE: For more information, refer to VLAN Stacking and VLAN-related commands, such as portmode hybrid in the Interfaces
chapter.
