Add New Uplink

Go to Devices and select an OLT, click VLAN/UPLINK and UPLINK Management on the Menu Bar, to access the uplink procedures.

Note: To find out whether traffic needs to be load-balanced, check each port’s 15-Minute Utilization on the Traffic Analysis tab (refer to Viewing GbE Port Statistics). If the percentages are significantly uneven, change the hashing algorithm.

Click on the Add New Button.
Select an available Interface AID from the drop-down list.
Enter a User Label of up to 32 printable characters.
If the Speed of the port(s) to be added to this uplink interface is not Auto-1000 (1G) (the default), select the Module Type=XFP, and the correct Speed from the drop-down list box. (All the uplinks in an interface must be at the same speed.) For 1G ports, accept the default value, Auto-1000 (1G), which enables communication of near-end faults to the far end.
Change the Hashing Algorithm. The purpose of the hashing algorithm is, when an uplink interface is a LAG, to randomly distribute (load balance) traffic across multiple ports. (If an uplink interface consists of a single port, the switch doesn’t use the hashing algorithm.) The default is Source and Destination MAC, which means that the switch extracts source and destination MAC address information from the Ethernet packets and uses this information to calculate which port carries the traffic. Because the results of the hashing algorithm are always the same, traffic from a particular source and/or destination (depending on the option specified) always uses the same port. For example, using Source and Destination MAC means that all traffic from a specific piece of equipment on the network to another specific piece of equipment in the network always travels on the same port. Traffic from adjacent equipment likely travels on a different port. Set either the default or Source and Destination IP for best results.
If necessary, change the DSCP Profile to mark traffic with the correct pbit based on the in-coming DSCP marking from the core network. Select a DSCP Profile directly from the drop-down list. The user can view or change the DSCP Profile, selecting Property directly from the Uplink Interface table.
If necessary, change Pause Frames’ value to match the setting of other equipment, such as the switch (default is checked ).
If necessary, change the Default VLAN value to the VLAN configured as the uplink interface from the dropdown list.
In the Available Links, if available, select the port(s) to include in this interface.

LACP Configuration

Note: LACP cannot be configured between the nodes of a ring.

Note: The configuration of the Link Aggregation Control Protocol (LACP) is an IEEE protocol that, as long as both ends of a connection support it, detects and removes non-functioning links from LAGs.

Check the Configure LACP box.
Click on the Mode: dropdown box to select an LACP Mode.

Passive (the default) means that this uplink interface waits for the other end to initiate an LACP connection. This setting is compatible with all equipment, regardless of whether it supports LACP or not.
Active means that this uplink initiates LACP connections. One or both ends of the connection must be Active in order for LACP to work. This setting requires that the equipment on the other end (such as a switch) support LACP. If it does not, LACP determines that the link is non-functioning and removes it.

Select a Timer value of Short (the default) or Long. This determines how long a link must be non-functioning before LACP removes it. The Short timeout is three seconds, while the Long timeout is 90 seconds.
Click the Apply button to add this configuration to the database.
To view the new uplink configuration, click Refresh () button.
