7.Port Priority: This is used to force any non prioritised packets to either High, Low, or Disabled states.

8.Port Security: Setting a ports security mode to on (by ticking the check box) will lock it to all unauthorized MAC addresses. This disables the address learning functionality on the port and then only incoming packets with a known source MAC addresses will be forwarded by the port. Administrators can disable the port from learning any new MAC addresses, and then use the static MAC addresses table entry screen to define a list of MAC addresses that can be used by the secure port.

2.4.5 Trunking

The Link Aggregation Control Protocol (LACP) provides a standardised means for exchanging information between Partner Systems that require high-speed redundant links. Link aggregation lets you group up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode, more detail information refers to the IEEE 802.3ad standard.

2.4.5.1 Aggregator setting

Link aggregation lets you group up to 4 consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network, such as another switch or a server, and also provide redundancy features.

1.System Priority: A value used to identify the active LACP. The switch with the lowest value has the highest priority and is selected as the active LACP.

2.Group ID: There are seven trunk groups provided. Choose the "group id" and click "Get" to display the group settings.

3.LACP: If enabled, the group defined in the ‘Work Ports’ is a LACP static trunking group. If disabled, the group is a LOCAL static trunking group (not LACP aware). By default all ports support LACP dynamic trunking. If the switch is connecting to a device that also supports LACP, then the LACP dynamic trunking group will be created automatically.
