The terminal connection to the device is provided through the MMB board only. For debugging and
management purposes, a UART bus of the Ethernet Connection Blade Module is connected to the MMB
board. The MMB board can select for management only one connection blade at a time. The Ethernet
Connection Blade Module also provides a in-band management interface for MMB management
purpose.

2.1 Features of the Ethernet Connection Blade
The Ethernet Connection Blade provides a wide range of advanced performance-enhancing features.
Multicast filtering provides support for real-time network applications. Port-based and tagged VLANs,
plus support for automatic GVRP VLAN registration provide traffic security and efficient use of network
bandwidth. QoS priority queuing ensures the minimum delay for moving real-time multi-media data
across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port
saturation. And broadcast storm suppression prevents broadcast traffic storms from engulfing the
network. Some of the management features are briefly described below.
Head of Line Blocking
Head of Line (HOL) blocking results in traffic delays and frame loss caused by traffic competing for the
same egress port resources. HOL blocking queues packets, and the packets at the head of the queue
are forwarded before packets at the end of the queue.
Flow Control Support (IEEE 802.3X)
Flow control enables lower speed devices to communicate with higher speed devices, by requesting that
the higher speed device refrains from sending packets. Transmissions are temporarily halted to prevent
buffer overflows.
Back Pressure Support
On half-duplex links, the receiving port prevents buffer overflows by occupying the link so that it is
unavailable for additional traffic.
Jumbo Frames Support
Jumbo frames are frames with an MTU size of up to 9K bytes, and better utilize the network by
transporting the same data using fewer frames. The main benefits of this facility are reduced
transmission overhead, and reduced host processing overhead. Less frames leads to less I/O interrupts.
This facility is typically used for server-to-server transfers.
MDI/MDIX Support
The Ethernet Connection Blade Module automatically detects whether the cable connected to an RJ-45
port is crossed or straight through. Standard wiring for end stations is Media-Dependent Interface (MDI)
and the standard wiring for hubs and switches is known as Media-Dependent Interface with Crossover
(MDIX).
Auto Negotiation
Auto negotiation allows an Ethernet Connection Blade Module to advertise modes of operation. The auto
negotiation function provides the means to exchange information between two devices that share a
point-to-point link segment, and to automatically configure both devices to take maximum advantage of
their transmission capabilities.

2.1.1 MAC Address Supported Features
MAC Address Capacity Support
The Ethernet Connection Blade Module supports up to 8K/32K MAC addresses for SB11a/SB11. The
Ethernet Connection Blade Module reserves specific MAC addresses for system use.
Static MAC Entries
MAC entries can be manually entered in the Bridging Table, as an alternative to learning them from
incoming frames. These user-defined entries are not subject to aging, and are preserved across resets
and reboots.
Self-Learning MAC Addresses
The Ethernet Connection Blade Module enables automatic MAC address learning from incoming
packets. The MAC addresses are stored in the Bridging Table
Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period are aged out. This prevents the
Bridging Table from overflowing.
Port Security
Port security prevents unauthorized users from accessing your network. It allows each port to learn, or
be assigned, a list of MAC addresses for devices authorized to access the network through that port.
Any packet received on the port must have a source address that appears in the authorized list,
otherwise it will be dropped. Port security is disabled on all ports by default, but can be enabled on a
per-port basis.
Address Filtering
This Ethernet Connection Blade provides a packet filter for all traffic entering the CPU port and hence
potentially forwarded or routed to the management network. The packet filter is rule/pattern based and
constitutes a set of patterns which when matched will DROP the packet, and a further set of patterns
which when matched will ACCEPT the packet.
MAC Multicast Support
Multicast service is a limited broadcast service, which allows one-to-many and many-to-many
connections for information distribution. Layer 2 Multicast services is where a single frame is addressed
to a specific Multicast address, from where copies of the frame are transmitted to the relevant ports.

2.1.2 Layer 2+ Features
IGMP Snooping/MLD Snooping
IGMP Snooping examines IGMP frame contents, when they are forwarded by the Ethernet Connection
Blade Module from work stations to an upstream Multicast router. From the frame, the Ethernet
Connection Blade Module identifies work stations configured for Multicast sessions, and which Multicast
routers are sending Multicast frames.
Port Mirroring
The mirror port mirrors both transmitted and received packets of the probe ports. In Ethernet Connection
Blade Module, it supports multiple probe ports and one mirror port. The mirror port mirrors packets of all
probe ports no matter whether these packets will eventually be dropped or not. User could set the probe
ports and mirror port by using the switch management function. On setting the probe port and mirror
port, users have to make sure both ports are configured to the same speed so that all packets could be
successfully mirrored. Physical ports and port-channel ports can be the probe ports.
Broadcast Storm Control
Storm control enables limiting the amount of switching IP packets. Since high rates and continuous
traffic can cause flooding on the network. The Storm control mechanism is to prevent the packets from
flooding into other parts of the network. Broadcast, multicast, and uni-cast forwarding rates are
supported. It provides users four different forwarding rates, 64, 128, 256, 512 pps (packets per second),
for broadcast, multicast, and uni-cast frames. Any traffic exceeding the configured forwarding rate will be
discarded in Ethernet Connection Blade. This function is disabled in default configuration.
VLAN Supported Features
The Ethernet Connection Blade supports up to 1000 VLANs and up to 4094 VLAN IDs. A Virtual LAN is
a collection of network nodes that share the same collision domain regardless of their physical location
or connection point in the network. The Ethernet Connection Blade supports tagged VLANs based on
the IEEE 802.1Q standard. Members of VLAN groups can be dynamically learned via GVRP, or ports
can be manually assigned to a specific set of VLANs. This allows the Ethernet Connection Blade to
restrict traffic to the VLAN groups to which a user has been assigned. By segmenting your network into
VLANs, user can:
a) Eliminate broadcast storms which severely degrade performance in a flat network.
b) Simplify network management for node changes/moves by remotely configuring VLAN membership
for any port rather than having to manually change the network connection.
c) Provide data security by restricting all traffic to the originating VLAN, except where a connection has
been configured between separate VLANs using a router or Layer 3 switch.
VLAN Support
VLANs are collections of switching ports that comprise a single broadcast domain. Packets are classified
as belonging to a VLAN based on either the VLAN tag or based on a combination of the ingress port and
packet contents. Packets sharing common attributes can be grouped in the same VLAN.
