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.
