FIGURE 49 – Viewing port security settings on a switch. On port 9, learning is enabled. This port
has 6 stations connected to it with the MAC addresses as shown. Other ports have
learning disabled and the MAC addresses are not configured on those ports ................................68
FIGURE 50 – Enabling learning on a port. Note – after the learning is enabled, the port security
can be queried to find the status of MAC addresses learnt. If there were machines
connected to this port, the MAC address would be shown on port 11 as they are shown on
port 9 .......................................................................................................................................68
FIGURE 51 – Allowing specific MAC address on specific ports. After the MAC address is
specified, the port or specific ports or a range of ports can be queried as shown..............................69

FIGURE 67 – VLAN as two separate collision domains. The top part of the figure shows two
“traditional” Ethernet segments. Up to 32 VLANs can be defined per switch.........................103
FIGURE 68 – Ports can belong to multiple VLANs. In this figure a simplistic view is presented
where some ports belong to VLANs 1, 2 and other ports belong to VLANs 2,3. Ports
can belong to VLANs 1, 2 and 3. This is not shown in the figure. .........................................104
