23 Preface
This chapter introduces and shows you how to access the EMS (Element Management
System).
1.1 EMS Overview
The Element Management System (EMS) retrieves management information from switches
using the SNMP protocol.
An EMS is composed of Network Elements (NE) that represent resources in a Network
Management System (NMS). The network elements can represent a physical piece of
equipment on the network, the components of a device on the network, or parts of the network
itself. The EMS is designed to manage the ES-3124 series, ES-2024A and GS-2024 switches
in the NMS. The ES-3124 series covers the ES-3124 and the ES-3124PWR.

5.2 Spanning Tree Protocol (STP)
STP detects and breaks network loops and provides backup links between switches, bridges or
routers. It allows a switch to interact with other STP-compliant switches in your network to
ensure that only one route exists between any two stations on the network.
5.2.1 STP Terminology
The root bridge is the base of the spanning tree; it is the bridge with the lowest identifier value
(MAC address).
Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned
according to the speed of the link to which a port is attached. The slower the media, the higher
the cost - see the next table.
Table 17 STP Path Costs
LINK SPEED RECOMMENDED VALUE RECOMMENDED RANGE ALLOWED RANGE
4Mbps 250 100 to 1000 1 to 65535
10Mbps 100 50 to 600 1 to 65535
16Mbps 62 40 to 400 1 to 65535
100Mbps 19 10 to 60 1 to 65535
1Gbps 4 3 to 10 1 to 65535
10Gbps 2 1 to 5 1to 65535
On each bridge, the root port is the port through which this bridge communicates with the root.
It is the port on this switch with the lowest path cost to the root (the root path cost). If there is
no root port, then this switch has been accepted as the root bridge of the spanning tree
network.
For each LAN segment, a designated bridge is selected. This bridge has the lowest cost to the
root among the bridges connected to the LAN.
5.2.2 How STP Works
After a bridge determines the lowest cost-spanning tree with STP, it enables the root port and
the ports that are the designated ports for connected LANs, and disables all other ports that
participate in STP. Network packets are therefore only forwarded between enabled ports,
eliminating any possible network loops.
STP-aware switches exchange Bridge Protocol Data Units (BPDUs) periodically. When the
bridged LAN topology changes, a new spanning tree is constructed.
Chapter 5 View 50
NetAtlas Enterprise Ethernet Switch Manager User’s Guide
Once a stable network topology has been established, all bridges listen for Hello BPDUs
(Bridge Protocol Data Units) transmitted from the root bridge. If a bridge does not get a Hello
BPDU after a predefined interval (Max Age), the bridge assumes that the link to the root
bridge is down. This bridge then initiates negotiations with other bridges to reconfigure the
network to re-establish a valid network topology.
5.2.3 STP Port States
STP assigns five port states (see next table) to eliminate packet looping. A bridge port is not
allowed to go directly from blocking state to forwarding state so as to eliminate transient
loops.

Disabled STP is disabled (default).

5.5 802.1D
Use the following screens to view a table of MAC address entries or to view a table of IP
address mappings.
5.5.1 802.1D: MAC Table
The MAC table shows how frames are forwarded or filtered across the switch’s ports. It shows
what device MAC address, belonging to what VLAN group (if any) is forwarded to which
port(s) and whether the MAC address is dynamic (learned by the switch) or static (manually
entered in Static MAC Forwarding).
The switch uses the Filtering Database to determine how to forward frames. See the following
figure.
1 The switch examines a received frame and learns the port on which this source MAC
address came.
2 The switch checks to see if the frame's destination MAC address matches a source MAC
address already learned in the Filtering Database.
• If the switch has already learned the port for this MAC address, then it forwards
the frame to that port.
• If the switch has not already learned the port for this MAC address, then the frame
is flooded to all ports. Too much port flooding leads to network congestion.
• If the switch has already learned the port for this MAC address, but the destination
port is the same as the port it came in on, then it filters the frame.

5.5.3 802.1D: ARP Table
Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP
address) to a physical machine address, also known as a Media Access Control or MAC
address, on the local area network.
An IP (version 4) address is 32 bits long. In an Ethernet LAN, MAC addresses are 48 bits
long. The ARP Table maintains an association between each MAC address and its
corresponding IP address.
5.5.4 How ARP Works
When an incoming packet destined for a host device on a local area network arrives at the
switch, the switch's ARP program looks in the ARP table and, if it finds the address, sends it to
the device.
If no entry is found for the IP address, ARP broadcasts the request to all the devices on the
LAN. The switch fills in its own MAC and IP address in the sender address fields, and puts the
known IP address of the target in the target IP address field. In addition, the switch puts all
ones in the target MAC field (FF.FF.FF.FF.FF.FF is the Ethernet broadcast address). The
replying device (which is either the IP address of the device being sought or the router that
knows the way) replaces the broadcast address with the target's MAC address, swaps the
sender and target pairs, and unicasts the answer directly back to the requesting machine. ARP
updates the ARP Table for future reference and then sends the packet to the MAC address that
replied.

6.3 IGMP Filter Template
Templates (also know as profiles) allow you to configure device IGMP filter settings
efficiently. The template can then be uploaded to one or more devices thus removing the need
to configure the IGMP filter settings for each device.
With the IGMP filter feature, you can limit the number of IGMP groups a subscriber on a port
can join. This allows you to control the distribution of multicast services (such as content
information distribution) based on service plans and types of subscription.
You can set the device to filter the multicast group join reports on a per-port basis by
configuring an IGMP filtering template and associating the profile to a port.
61 Chapter 6 Template
NetAtlas Enterprise Ethernet Switch Manager User’s Guide
IGMP filter templates allow you to control access to IGMP multicast groups. This allows you
to have a service available to a specific IGMP multicast group. You can configure an IGMP
filter template for an IGMP multicast group that has access to a service (like a SIP server for
example).
6.3.1 IP Multicast Addresses
In IPv4, a multicast address allows a device to send packets to a specific group of hosts
(multicast group) in a different subnetwork. A multicast IP address represents a traffic
receiving group, not individual receiving devices. IP addresses in the Class D range (224.0.0.0
to 239.255.255.255) are used for IP multicasting. Certain IP multicast numbers are reserved by
IANA for special purposes (see the IANA web site for more information).

6.4 Static Multicast Group Template
Use the static multicast filter to allow incoming frames based on multicast MAC address(es)
that you specify. This feature can be used in conjunction with IGMP snooping to allow
multicast MAC address(es) that are not learned by IGMP snooping. Use the static multicast
filter to pass routing protocols, such as RIP and OSPF.
A static multicast group template allows you to configure multicast filters efficiently. The
template can then be uploaded to one or more devices thus removing the need to configure the
static multicast filter settings for each device.
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1
recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets
to just a group of hosts on the network.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish
membership in a multicast group - it is not used to carry user data. Refer to RFC 1112 and RFC
2236 for information on IGMP versions 1 and 2 respectively.
You can set the switch to forward multicast data to specific port(s). This is essential for
sending multicast traffic to hosts that cannot report their membership with IGMP.
Chapter 6 Template 64
NetAtlas Enterprise Ethernet Switch Manager User’s Guide
6.4.1 Multicast MAC Address
All Ethernet devices must have a unique MAC address to communicate with one another.
Device such as routers and switches on the LAN keeps a table of MAC-IP address mappings.
When a packet is received, the destination IP address is looked up in the address mapping table
and the packet is forwarded to the intended Ethernet device. IP multicast packets are in the
Class D group addresses, thus an IP multicast address does not correspond to a unique
Ethernet device.
The IANA has reserved a range of address (01:00:5e:00:00:00 to 01:00:5e:7f:ff:ff in
hexadecimal notation) for multicasting. This range gives 23 usable bits. The IP-MAC
multicast address mapping is done by copying the lower-order 23-bit of a Class D address to
the lower-order 23-bit of the MAC multicast address.
The following figure shows an example.
Figure 32 Multicast MAC-IP Address Mapping Example
Since 32 Class D addresses are mapped to the same multicast MAC address, filtering (by
checking the destination IP address) is recommended on the Ethernet devices to reduce
excessive multicast packets.
