The IBM BladeCenter Layer 2/3 Copper and Fiber Gigabit Ethernet
Switch Modules for standard mode of operation includes the
following features and functions:
- Internal ports
- 14 internal full-duplex Gigabit ports, one connected to each of
the blade servers in the BladeCenter unit
- Two internal full-duplex 10/100 Mbps ports connected to the
management module
- External ports
- Copper switch: Six 1000BASE-T copper RJ-45 connections for
making 10/100/1000 Mbps connections
- Fiber switch: Six 1000BASE-SX SFP transceiver-based LC fiber
connections for making 1000 Mbps connections
- An RS-232 serial port that provides an additional means to
install software and configure the switch module
- Scalability and performance
- Autosensing 10/1000/1000 Mbps external Ethernet ports for
bandwidth optimization
- Non-blocking architecture with wire-speed forwarding of
traffic
- Media access control (MAC) address learning: automatic update,
supports up to 16 K MAC addresses
- Up to 128 IP interfaces per switch
- Static, EtherChannel, and LACP (IEEE 802.3ad) link aggregation,
up to 6 Gb of total bandwidth per switch, up to three trunk groups,
and up to six ports per group
- Support for jumbo frames (up to 9216 bytes)
- Broadcast/multicast storm control
- IGMP snooping for limit flooding of IP multicast traffic (IGMP
V1, V2, and V3)

participating in multicast groups (IGMP V1, V2, and V3)
- Configurable traffic distribution schemes over trunk links
based on source/destination IP addresses, MAC addresses, or
both
- Fast port forwarding and fast uplink convergence for rapid STP
convergence
- Availability and redundancy
- VRRP for Layer 3 router redundancy
- IEEE 802.1D STP for providing Layer 2 redundancy with
PVRST+
- IEEE 802.1s Multiple STP (MSTP) for topology optimization, up
to 128 STP instances are supported by single switch

of network adapter teaming on blades
- Interchassis redundancy (Layer 2 and Layer 3)
- VLAN support
- Up to 1024 VLANs supported per switch; VLAN numbers ranging
from 1 to 4095 (4095 is used for the management module’s connection
only)

source and destination addresses, VLANs) traffic classification and
processing
- Traffic shaping and re-marking based on defined policies
- Eight Weighted Round Robin (WRR) priority queues per port for
processing qualified traffic
- Layer 3 functions

indication
- Port mirroring for analyzing network traffic passing through
switch
- Change tracking and remote logging with syslog feature
- POST diagnostics
