8.1 VLAN Configuration
VLAN (Virtual Local Area Network) is a logical (virtual) local area network that represents a group of devices,
which communicate on channel level regardless of their physical location. VLAN operation is based on the use
of additional Ethernet header fields according to 802.1q standard. In fact, VLAN isolates the broadcast domain
by limiting the switching of only those Ethernet frames which have the same VLAN-ID in the Ethernet header.
8.1.1 Configuration algorithm
Step Description Command Keys
1 Create VLAN. esr(config)# vlan <VID> <VID> – VLAN identifier, set in the

<vlan-name> – up to 255 characters.
3 Disable monitoring of the status
of interfaces on which processing
of the given VLAN Ethernet
frames is allowed (optional).
esr(config-vlan)# force-up
4 Disable the processing of
incoming untagged Ethernet
frames based on the default
VLAN's switching table (VLAN-ID
– 1) (optional).
