•
LLDP
•
Ports
Workflow
To configure ports, perform the following actions:
1
Configure port by using the Ports page
2
Enable/disable the Link Aggregation Control protocol, and configure the
potential member ports to the desired LAGs by using the LAGs page By
default, all LAGs are empty
3
Configure the Ethernet parameters, such as speed and auto-negotiation
for the LAGs by using the LAGs page
4
Configure the LACP parameters for the ports that are members or
candidates of a dynamic LAG by using the LAGs page
5
Configure Green Ethernet and 802 3 Energy Efficient Ethernet by using
the Green Ethernet page
6
Configure Green Ethernet energy mode and 802 3 Energy Efficient
Ethernet per port by using the Green Ethernet page
7
If PoE is supported and enabled for the device, configure the device as
described in PoE
8
Configure LLDP and LLDP-MED Port feature by using Discovery LLDP
Configure Port Settings
To configure port settings:
STEP 1 Click Configuration > Port Management > Ports
STEP 2 Select Enable to support jumbo packets of up to 10 KB in size If
Jumbo Frames is not enabled (default), the system supports packet
size up to 2,000 bytes For Jumbo Frames to take effect, the device
must be rebooted after the feature is enabled
STEP 3 To update the port settings, select the desired port, and click Edit
STEP 4 Modify the following parameters:
Port—Select the port number
•
Port Settings
Operational Status—Displays whether the port is currently up or down
•
If the port is down because of an error, the description of the error is
displayed
Administrative Mode—Select to bring the port up or down
•
Suspended Port—Select to reactivate a port that has been suspended
•
The reactivate operation brings the port up without regard to why the
port was suspended
Protected Port—Select to make this a protected port (A protected port is
•
also referred to as a Private VLAN Edge (PVE) ) The features of a protected
port are as follows:
Protected Ports provide Layer 2 isolation between interfaces (Ethernet
•
ports and LAGs) that share the same VLAN
Packets received from protected ports can be forwarded only to
•
unprotected egress ports Protected port filtering rules are also applied to
packets that are forwarded by software, such as snooping applications
Port protection is not subject to VLAN membership Devices connected to
•
protected ports are not allowed to communicate with each other, even if
they are members of the same VLAN
Both ports and LAGs can be defined as protected or unprotected
•
Protected LAGs are described in the LAGs section
Auto Negotiation—Select to enable auto-negotiation on the port Auto-
•
negotiation enables a port to advertise its transmission speed, duplex
mode, and flow control abilities to the port link partner
