5.9. Ethernet Switch - Detailed Requirements
In the virtual matrix architecture a third party switch is used to transfer IP packets. In connection with this
switch, the following criteria must be met:
▪ 10 Gbps non-blocking switch (capable of full bandwidth transmission between all ports)
▪ Supports IEEE Std. 802.3ad-2000 Link Aggregation Control Protocol, with Link Aggregation Groups for each
endpoint.
▪ Supports Internet Group Management Protocol version 2 (RFC 2236) snooping.
▪ IPv4 (or Layer 2) Multicast Forwarding based on IGMP v2 snooping, with at least 16 addresses available for
each endpoint, e.g. 4096 IPv4 multicast addresses for 256 endpoints.
▪ Supports IEEE Std. 802.1Q VLAN tagging: 1 VLAN reserved for UBEX control and media transmission,
other(s) available for user traffic.
Optional Requirements:
▪ Supports IEEE Std. 802.1Q (formerly 802.1p) priority code point (PCP), and implements priority based
queuing for at least 1 prioritized traffic class. This is required to guarantee uninterrupted media
transmission regardless of the user traffic.
▪ Supports Link Layer Discovery Protocol (LLDP), in order to discover network topology.
▪ Supports IEEE Std. 802.1s (merged into IEEE Std. 802.1Q-2005) Multiple Spanning Tree Protocol
(MSTP), in order to detect switching loops in VLAN's.

5.10. Ethernet Switch Configuration

ATTENTION!
5.10.1. Link Aggregation (LAG)

DEFINITION:
multiple network connections in parallel in order to increase throughput beyond what a single connection
could sustain.
Create Link Aggregation Groups (LAG's)/EtherChannels etc. for each port pair that is used for 20 GbE
transmission (LAG is not necessary for the ports which are used for 10 GbE transmission). The bonding
mode is dynamic: 802.3-ad LACP has to be enabled for each group.
5.10.2. VLAN

DEFINITION:
network at the data link layer (OSI layer 2). LAN is the abbreviation for local area network and in this
context, virtual refers to a physical object recreated and altered by additional logic.
The UBEX network uses 802.1Q tagged frames with the VLAN ID of 286. This VLAN has to be available from each
LAG, with tagged frames. The LAG's have to be in trunk mode (multiple VLAN's are available on UBEX devices,
other VLAN's may be used with tagged or untagged frames).
The port where the MMU is connected is also a trunk port.
5.10.3. IGMPv2

DEFINITION:
traffic. The feature allows a network switch to listen in on the IGMP conversation between hosts and
routers.
IGMPv2 snooping has to be enabled for each LAG in this VLAN.
5.10.4. Optional Configuration
Enable Link Layer Discovery Protocol (LLDP) on all ports to access topology information in order to speed
up your installation process.

The UBEX extenders do not support jumbo/giant frames.
The Link Aggregation Group (LAG) applies to various methods of combining (aggregating)
A virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer
IGMP snooping is the process of listening to Internet Group Management Protocol network
