Virtual LAN (VLAN) Commands
The following commands configure and monitor virtual local area networks (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 virtual router
redundancy protocol (VRRP) state of a VLAN interface may continually switch between Master and
Backup.
