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
