GS700TP Smart Switch Software Administration Manual
4-4 Configuring Switching Settings
v1.0, December 2007
•MDI/MDIX – Select the MDI/MDIX status of the port. Hubs and switches are
deliberately wired opposite the way end stations are wired, so that when a hub or switch is
connected to an end station, a straight through Ethernet cable can be used and the pairs
will match up properly. When two hubs or switches are connected to each other or two end
stations are connected to each other, a crossover cable is used to ensure that the correct
pairs are connected. The possible field values are:
– Auto – Provides automatic cable type detection.
– MDI (Media Dependent Interface) – Connects end stations.
– MDIX (Media Dependent Interface with Crossover) – Connects HUBs and switches.
•LAG ID – Select the LAG ID to which the selected port is assigned.
2. Select the interface.
3. Enter or modify the fields in the first row.
4. Click Apply to update the device.
LAG
A Link Aggregated Group (LAG) optimizes port usage by linking a group of ports together to
form a single LAG. Aggregating ports multiplies the bandwidth between the devices, increases
port flexibility, and provides link redundancy. Ports added to a LAG lose their individual port
configuration. When ports are removed from the LAG, the original port configuration is applied to
the ports. Ensure the following, when configuring LAGs:
• All ports within a LAG must be of the same media type.
• A VLAN is not configured on the port.
• The port is not assigned to a different LAG.
• Auto-negotiation mode is not configured on the port.
• The port is in full-duplex mo de.
• All ports in the LAG have the same ingress filtering and tagged modes.
• All ports in the LAG have the same back pressure and flow control modes.
• All ports in the LAG have the same priority.
• All ports in the LAG have the same transceiver type.
• The d evice supports up to eight LAGs with eight ports in each LAG.
