VLANs on the ELS10-27MDU
9033276
5
The ELS10-27MDU supports some 802.1Q VLAN capabilities. Static
capabilities are provided. GVRP is not supported at this time.
The ELS10-27MDU operates in 802.1Q mode only. All ports are configured
as access ports. When a packet is received, an 802.1Q tag is inserted into
the packet. This tag and the MAC address are used to forward the packet.
Only ports that are members of this VLAN may receive the packet.
Each of the 10Mbps ports is a separate VLAN with only the CPU and the
100Mbps uplink port as members of this VLAN. When packets are
received on the 10Mbps ports, they can only be forwarded to the CPU
and/or the 100Mbps uplink. The 100Mbps downlinks are configured the
in the same manner. This restricts traffic between the uplink and
downlinks.
The 100Mbps uplink is a member of all the 10Mbps ports VLANs, and also
has its own VLAN, with all the 10Mbps ports as members. The default
VLAN id for a port is its port number plus one as shown in Table 1. The
VLAN id of one is reserved.
