Multicasting; Port Mirroring - IBM 8677 - BladeCenter Rack-mountable - Power Supply Planning And Installation Manual

Figure 43 shows an example of VLANs that span multiple BladeCenter units. In this
example layer 2 VLANs span the BladeCenter units within each rack. Layer 3
subnets separate the VLANs into segments.

Multicasting

To configure multicasting, determine the settings to be used for IGMP snooping and
the entries to be included in the multicast forwarding table.

Port mirroring

The switch module provides the capability of copying frames that were transmitted
and received on a source port and redirecting the copies to another target port. The
source port can be one of the four 10/100/1000 Mbps external ports. The target port
is where you will connect a monitoring/troubleshooting device, such as a sniffer or
an RMON probe. The target port must be one of the four 10/100/1000 Mbps
external ports.
