Mobility Point™ Access Points

Distributed MPs and Link Autonegotiation

Description

The Ethernet interfaces on an MP are configured to autonegotiate the link speed (10 Mbps or

100 Mbps) and mode (half duplex or full duplex). The setting cannot be changed. A common setting on

third-party switches is 100 Mbps, with full duplex. If you connect a Distributed MP to a port that is set for

100 Mbps with full duplex, the MP operates at 100 Mbps with half duplex. This results in an unusable link.

Workaround

Configure the port on the other device to autonegotiate.

Distributed MPs and STP

Description

A Distributed MP is a leaf device. You do not need to enable STP on the port that is directly

connected to the MP.

If Spanning Tree Protocol (STP) is enabled on the port that is directly connected to a Distributed MP, you

might need to change the STP configuration on the port, to allow the MP to boot.

MP-620 BNC Connector Is Not Used As part of the boot process, an MP disables and reenables the link on the port over which the MP is attempting to boot. If STP is enabled on the device that is directly connected to the port, the link state change can cause the port on the other device to leave the forwarding state and stop forwarding traffic. The port remains unable to forward traffic for the duration of the STP forwarding delay.

Power Over Ethernet Support Power Over Ethernet Support Trapeze Networks recommends that you budget for a minimum of 9 Watts of power draw per MP, for model MP-372. For an MP-620, budget for a maximum power draw of 30 Watts. For all other models, budget for a maximum power draw of 8 Watts per MP. Table 1 lists the Power over Ethernet (PoE) sources from which MPs can accept power. Table 2 lists the MP models that support 802.3af and the 802.3af classes of these models. Table 1.
