Server-Port Configuration

A blade server is assigned a specific port on the blade switch. This assignment is predetermined by the physical slot the blade server occupies in the enclosure. Table 1 correlates the server and switch ports.

The server ports on the blade switch support a single VLAN access and trunk configuration mode. The operational mode chosen should support the server NIC configuration (that is, a trunking NIC is attached to a trunking switch port). Enable PortFast for the edge devices.

The BPDU Guard feature disables a port that receives a BPDU. This feature protects the Spanning Tree Protocol topology by preventing the blade server from receiving BPDUs. An administrator must manually recover a port disabled with the BPDU Guard feature. Enable the BPDU Guard feature on all server ports that should not be receiving BPDUs.

Port Security limits the number of MAC addresses permitted to access the blade-switch port. Configure the maximum number of MAC addresses expected on the port.

Note: The NIC teaming driver configuration (that is, the use of a virtual MAC address) must be considered when configuring Port Security.
