VLANS
A VLAN (802.1Q Virtual Local Area Network) is used to separate broadcast domains via software instead of via
hardware (physical layout of network devices and cabling). Software on network nodes (like the T850) abstracts this
into virtual network interfaces, so each interface can have its own virtual interface configuration (static address, subnet
mask, router). The unit operates with virtual interfaces the same as it would with real interfaces.
Configuration
Each Ethernet interface can have up to 6 VLANs bound to it. Access configration items via any of the following:
Menu: Setup -> Network Settings -> Ethernet Settings -> Ethernet x -> VLAN Settings
Web: Networking -> Ethernet Settings -> Ethernet x Settings -> scroll down to VLANx Settings
Keys:
net.eth[].vlan[].id
net.eth[].vlan[].priority
net.eth[].vlan[].ip
net.eth[].vlan[].mask
net.eth[].vlan[].router
net.eth[].mode
VLAN ID
0 to 4094; this is what identifies the VLAN.
VLAN priority
0 to 7; this is the priority assigned to egress frames.
IP, mask, router
Configured like any other interface. This router setting is included in the set of candidate default routers which
the unit can use. The unit does not yet support configuration of individual host and network routes. Select the
default router with the
net.default.router
setting, if the unit has not already selected an appropriate one
for you. Note that the unit does not heed changes to network configuration while you are connected to a
command processor via Telnet or SSH. Changes, including population of the candidate default router set, are
pended until all network-based command processor sessions have ended.
Network mode
Set this to VLAN to engage the interface in VLAN mode. While the interaface operates in VLAN mode, its
normally configured settings (IP, mask, router) are still configured but the interface does not use them. The
interface heeds those settings only when it's in STATIC mode.
Example
Put the unit on three VLANs bound to the cable attached to the first Ethernet adapter, 10.20.20.0/24, 10.30.30.0/24,
and 10.40.40.0/24, with VLAN ids 20, 30, and 40, respectively. The unit will route off its local nets via the 10.30.30.1
router.
Configure:
net.eth[1].vlan[1].id =20
net.eth[1].vlan[1].ip =10.20.20.2
net.eth[1].vlan[1].mask =255.255.255.0
net.eth[1].vlan[2].id =30
net.eth[1].vlan[2].ip =10.30.30.2
net.eth[1].vlan[2].mask =255.255.255.0
net.eth[1].vlan[2].router =10.30.30.1
net.eth[1].vlan[3].id =40
net.eth[1].vlan[3].ip =10.40.40.2
net.eth[1].vlan[3].mask =255.255.255.0
net.eth[1].mode =vlan
If no other interfaces are active then the unit will select 10.30.30.1 as the default router (gateway); if other routers are
configured for other interfaces then you can override this by configuring
net.default.router
.
