Configuring IP Subnet VLANs
– 198 –
The interface must be configured as a member of the subnet VLAN.
The IP address and subnet mask of the inbound packet must fall within
specified subnet VLAN
The above conditions mean that any ARP requests will not be forwarded within
the subnet VLAN because they are EtherType 0x0806 and do not meet the
requirements for an IP subnet VLAN. For example, ping requests must pass
through and IP subnet VLAN.
Also, note that TCP/UDP port numbers are not considered when checking
whether or not packets are forwarded within the subnet VLAN
The IP subnet cannot be a broadcast or multicast IP address.
When MAC-based, IP subnet-based, or protocol-based VLANs are supported
concurrently, priority is applied in this sequence, and then port-based VLANs
last.
Parameters
These parameters are displayed:
IP Address – The IP address for a subnet. Valid IP addresses consist of four
decimal numbers, 0 to 255, separated by periods.
Subnet Mask – This mask identifies the host address bits of the IP subnet.
VLAN VLAN to which matching IP subnet traffic is forwarded.
(Range: 1-4094)
Priority – The priority assigned to untagged ingress traffic.
(Range: 0-7, where 7 is the highest priority; Default: 0)
