P130 Features

The standard P130 features of the switch are described below.

Auto-Negotiation

Every 10/100 port on the P130 supports Auto-Negotiation which automatically detects and supports the duplex mode and speed of a connected device. Auto- negotiation is also supported on the Gigabit Ethernet ports for flow control mode only.

This means that you can simply connect the P130 to Ethernet or Fast Ethernet equipment at full or half duplex without configuration.

Link Aggregation Group (LAG)

LAG provides increased bandwidth and redundancy for critical high-bandwidth applications such as inter-switch links and connections to servers. You can aggregate the bandwidth of up to eight 10/100Base-Tx or two 1000Base-X ports.

Load sharing ensures that if one of the port connections fails, the other connections will assume the load seamlessly. Load balancing guarantees that the traffic load at any level will be divided among all the LAG links (see also the LAG documentation module).

LAGs can be created in the switch in order to increase bandwidth and resiliency in switch-to-switch and server-to-switch connections. P133T supports up to 3 LAGs, P133G2, P133GT2 and P133F2 support up to 4 LAGs, P134G2 supports up to 6 LAGs.

Each LAG is considered a single switch interface. Packets are not forwarded between its ports, and non-unicast packets are transmitted only through one port - the "Flood"(or "Base") port. In addition, packet order is maintained within each session.
