GE-DS-82 and 82-PoE Ethernet Managed Switch User Manual 155
show lacp port
Description:
Show LACP information by port.
Syntax:
show lacp port <port-id>
Parameters:
<port-id> specifies the port to be shown.
NOTE: If VLAN group exists, all of the members of static trunk group must be in same
VLAN group.
VLAN Configuration
Virtual LANs
A Virtual LAN (VLAN) is a logical network group that limits the broadcast domain. It
allows you to isolate network traffic so only members of the VLAN receive traffic from
the same VLAN members. Basically, creating a VLAN within a switch is logically
equivalent of reconnecting a group of network devices to another Layer 2 switch.
However, all the network devices are still plugged into the same switch physically. A
station can belong to more than one VLAN group. VLAN prevents users from
accessing network resources of another on the same LAN, thus the users can not see
the hard disks and printers of another user in the same building. VLAN can also
increase the network performance by reducing the broadcast traffic and enhance the
security of the network by isolating groups.
The GE-DS-82-PoEsupports two types of VLANs:
• Port-based
• IEEE 802.1Q (tag) -based
Only one of the two VLAN types can be enabled at one time.
Port-based VLANs are VLANs where the packet forwarding decision is made based on
the destination MAC address and its associated port. You must define the outgoing
ports allowed for each port when you use port-based VLANs. In port-based VLANs,
the packets received from one port can only be sent to the ports which are
configured to the same VLAN. As shown in the following figure, the switch
administrator configured port 1-2 as VLAN 1 and port 3-4 as VLAN 2. The packets
received from port 1 can only be forwarded to port 2. The packets received from port
