Figure 21 — Add/Modify VLAN Group for 24-port Models
(The 16-port model webpage is similar except that ports 17–24 are not present.)
4.4.4.7 Management Port
Below the group settings is the “Management Port” checkbox (appearing repeatedly
below each row in Figure 20 or singly atop Figure 21). For a VLAN group to extend
management functionality to any of its ports, the Management Port must be included as
a member. This port does works solely within the Ethernet controller chip — it has no
physical port. A VLAN group that excludes this port can add security to its ports — but
such a group cannot support IGMP Snooping, the web server or SNMP.
For 8-port models, modify a VLAN group via the individual groups in Figure 20. For
16- and 24-port switches (using the features shown in Figure 21), enter the Group
number you wish to modify then click the Modify Group No button. This populates the
top portion of the screen with current settings for the selected Group No. You can then
make changes and click Apply. The modified settings can be confirmed by checking the
read-only text box in the lower section of the webpage as shown in Figure 21.
