Port Management Link Aggregation 2 • Neighbor Advertisement - The neighbor port (the port to which the selected interface is connected) advertises its capabilities to the port to start the negotiation process. • Back Pressure - Enables Back Pressure mode on the port. Back Pressure mode is used with Half Duplex mode to allow ports to prevent the link partner from sending traffic. The Back Pressure mode is configured for ports currently in the Half Duplex mode. • Current Back Pressure - Displays the Back Pressure mode on the port. • Flow Control - Enables or disables flow control or enables the auto negotiation of flow control on the port. • Current Flow Control - Displays the current Flow Control setting. • MDI / MDIX - Defines the Media Dependent Interface (MDI) / Media Dependent Interface with Crossover (MDIX) mode on 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 are matched 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: - MDIX - Use for hubs and switches. - Auto - Use to automatically detect the cable type. - MDI - Use for end stations. • Current MDI / MDIX - Displays the current MDI / MDIX setting. • LAG - Indicates the LAG number of which this port is a member, if relevant. STEP 2 Define the relevant fields. STEP 3 Click Save Settings. The settings are modified, and the device is updated. Link Aggregation Link Aggregated Groups optimize port usage by linking a group of ports together to form a single aggregated group. Link aggregated groups multiply the bandwidth between the devices, increase port flexibility, and provide link redundancy. Cisco Small Business SLM Series Smart Switches Administration Guide 17
