Features and specifications
The IBM 1/10 Uplink Ethernet Switch Module includes the following standard features
and functions:
򐂰 Internal ports:
– 14 internal full-duplex Gigabit ports, one connected to each of the blade servers.
– Two internal full-duplex 10/100 Mbps ports connected to the management module.
– External ports:
• Three slots for 10 Gb Ethernet SFP+ transceivers (support for 10GBASE-SR or
10GBASE-LR) or SFP+ copper direct-attach cables (DAC); SFP+ modules are
optional
• Six 10/100/1000 1000BASE-T Gigabit Ethernet ports with RJ-45 connectors
• One RS-232 serial port that provides an additional means to install software and
configure the switch module
򐂰 Scalability and performance:
– Fixed-speed external 10 Gb Ethernet ports for maximum uplink bandwidth.
– Autosensing 10/1000/1000 external Gigabit 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 and LACP (IEEE 802.3ad) link aggregation, up to 36 Gb of total bandwidth per
switch, up to 16 trunk groups, 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 filtering to control multicast traffic for hosts that participate in multicast groups.
– Configurable traffic distribution schemes over trunk links based on source/destination
IP or 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 L2 redundancy.
– IEEE 802.1s Multiple STP (MSTP) for topology optimization. Up to 128 STP instances
are supported by single switch.
– IEEE 802.1w Rapid STP (RSTP) provides rapid STP convergence for critical
delay-sensitive traffic like voice or video.
