4, 5, 7, 8 NC

The Fast Ethernet ports support 10BASE-T and 100BASE-TX, full- or half-duplex modes. All the Fast Ethernet ports auto­detect the signal from connected devices to negotiate the link speed and duplex mode. Auto MDI/MDIX allows you to connect
another switch, hub, or workstation without changing straight-through or crossover cables. Crossover cables cross-connect the
transmit lines at each end to the received lines at the opposite end.

The Ethernet cables use Pins 1, 2, 3, and 6 of an 8-pin RJ45 connector. The signals of these pins are converted by the automatic
MDIX function, as shown in the following table.

about combo port functionality.

25-28) for information

Connect SFP Transceivers (Combo Ports 25-28)

Optionally, connect SFP transceivers. Comtrol
recommends using Comtrol gigabit SFP transceivers.

The RocketLinx ES7528 equips four gigabit SFP ports
combined with gigabit Ethernet ports. The SFP ports
accept standard mini GBIC SFP transceivers that support
1000BASE-SX/LX/LHX/XD/ZX. To ensure system
reliability, Comtrol recommends using a Comtrol
certified gigabit SFP Transceiver. The certified SFP
transceiver includes 1000BASE-SX/LX single/multi
mode range from 550m to 80km.

1. Plug the SFP transceiver into the SFP fiber

transceiver.

2. Connect the transmit channel to the receive channel at each end.

3. Check the direction/angle of the fiber transceiver and the fiber cable.

Note: This is a Class 1 Laser/LED product. Don’t stare at the Laser/LED Beam.

The SFP port does not function until the fiber cable is linked to another active device. The SFP and corresponding RJ45 ports
work in an exclusive mode. Traffic sent or received through the SFP module has priority thus no traffic is sent or received over
the corresponding RJ45 connection. To use the RJ45 connection, remove the corresponding SFP.

Connect the Digital or Relay Output

If desired, connect the Digital or Relay Output. The relay contacts are energized, (open) for normal operation and close for
fault conditions. The fault conditions include:

• Power failure

• Ethernet port link break

• Other pre-defined events, which you can configure in the RocketLinx ES7528 user interface. See Fault Relay

for detailed information.

Jumbo Frame

Jumbo Frame

The typical Ethernet frame range is from 64 to 1,518 bytes. This is
sufficient for general usages. However, when users want to transmit
large files, the files may be divided into many small size packets.
When the transmission speed becomes slow, long size Jumbo frame
may solve the issue.

The RocketLinx ES7528 allows you configure the size of the
Maximum Transmission Unit (MTU). The default value is 1,518
bytes. You can increase the MTU size to support jumbo frames on
all interfaces by setting the Jumbo Frame MTU. The maximum
Jumbo Frame size is 9,216 bytes. You can freely change the
available packet size.

Jumbo Frame Description

System MTU Change the MTU size for all Fast Ethernet interfaces on the switch stack. The

range is 1500 to 1546 bytes; the default is 1518 bytes.

DHCP Relay Agent

This subsection discusses the DHCP Relay Agent.

DHCP Relay Agent Description

Relay Agent You can select to Enable or Disable DHCP relay agent function,

and then select the modification type of option 82 field.

The DHCP Information option referred to as Option 82 is normally

used in environments of large enterprise or metro networks to
provide additional data on the physical attachment of the client.
Option 82 is suggested for use in distributed DHCP server/relay
environments, where relays insert additional information to
identify the client’s attachment point.

Relay policy drop Drops the option 82 field and does not add any option 82 fields.

Relay policy keep Keeps the original option 82 field and forwards it to the server.

Relay policy replace Replaces the existing option 82 field and adds the new option 82

field. (This is the default setting)

Helper Address There are four fields for the DHCP server’s IP address. You can fill

the field with a preferred IP address of the DHCP Server. All the
DHCP packets from client are modified by the policy and for­warded to the DHCP server through the gateway port.

Apply Click Apply to apply the settings.

Note: You must Save the settings (Page 137), if you want to

Backup and Restore

Backup and Restore

Use the Backup command to save the current configuration file saved in the switch’s
flash to admin PC or TFTP server. This allows you to go to the Restore command

later to restore the configuration file back to the RocketLinx ES7528. Before you
restore the configuration file, you must place the backup configuration file in the PC
or TFTP server. The switch then downloads this file back to the flash.

The RocketLinx ES7528configuration file is a pure text file. You can open the file
with Word or Notepad. You can also modify the file, add/remove the configuration
settings, and then restore back to the RocketLinx ES7528.

There are two modes to backup/restore the configuration file: Local File mode and
TFTP Server mode. Click the Folder icon to select the target file you want to backup/

restore.

Note: Folders of the path to the target file do not allow you to input space key.

Backup and Restore Description

Backup Configuration • Local File: In this mode, the switch acts as the file server. Browse to the target folder and

then type the file name to backup the configuration. You can also browse to the target
folder and select an existing configuration file to restore the configuration back to the
switch. This mode is only provided by the web UI as the backup and restore functions are
not supported by the CLI.

• TFTP Server: In this mode, the switch acts as TFTP client. Confirm that your TFTP

server is ready, then enter the IP address of TFTP Server and Backup configuration file
name. This mode can be used in both the CLI and web interface.

- TFTP Server IP Address: Enter the IP address of your TFTP Server.

- Backup File Name: Enter the name of the backup file.

Note: Pointing to the wrong file causes the entire configuration to be skipped.

Backup The Backup command can only backup the configuration file to your PC or TFTP server.

Restore Configuration You can select local file or TFTP server to restore startup configuration.

• Local File: The file name of startup configuration file to be uploaded.
Restore File Name: You can enter the configuration file name, or use file chooser to select

Technical Tip:

If both ends are not at the same speed, they cannot link with each other. If both ends are not in the
same duplex mode, they are connected by half-duplex mode.

Port Configuration Description

State You can enable or disable the state of this port. Once you click Disable, the

port stops to link to the other end and stops to forward any traffic. The default

setting is Enable which means all the ports are workable when you receive

the RocketLinx ES7528.

selections you can choose:

• Fast Ethernet Port 1~24 (fa1~fa24)

- Auto Negotiation

- 10M full-duplex (10 Full)

- 10M half-duplex (10 Half)

- 100M full-duplex (100 Full)

- 100M half-duplex (100 Half)

- Gigabit Ethernet Port 25~28: (gi25~gi28Auto Negotiation

- 10M full-duplex (10 Full)

- 100M half-duplex (100 Half)

- 1000M full-duplex (1000 Full)

Note: The default mode is Auto Negotiation mode.

Flow Control Symmetric means that you need to activate the flow control function of the

remote network device in order to let the flow control of that corresponding
port on the switch to work.

Disable means that you do not need to activate the flow control function of

the remote network device, as the flow control of that corresponding port on
the switch works.

ing Eject All.

Note: Most of the SFP transceivers provide vendor information which allows the RocketLinx ES7528 to read it. The user

interface can display vendor name, wave length, and distance of all Comtrol SFP transceiver models. If you see
Unknown info, it may mean that the vendor does not provide their information or tha t the information of their
transceiver cannot be read.

If the plugged DDM SFP transceiver is not certified by Comtrol, the DDM function is not supported, but the
communication is not disabled.

Rate Control

Rate limiting is a form of flow control used to enforce a strict bandwidth limit at a port.
You can program separate transmit (Egress Rule) and receive (Ingress Rule) rate limits at
each port, and even apply the limit to certain packet types as described below. You can
increment the volume step by 64Kbps in the blank.

Rate Control Description

Limit Packet
Type

Bandwidth The ports support port ingress and egress rate control. For example,

Ingress Ingress rate in Kbps, the rate range is from 1000 Kbps to 1000000 Kbps

Egress Egress rate in Kbps, the rate range is from 1000 Kbps to 1000000 Kbps

The packet types all types of packets, broadcast/multicast/unknown
unicast packets, broadcast/multicast packets, and broadcast packets
only.The ingress rate supports all types of packets. The egress rate
supports all types of packets.

assume that Port 1 is 10000 Kbps, you can set it's effective egress rate at
2000 Kbps, ingress rate is 1000 Kbps. The switch performs the ingress
rate by packet counter to meet the specified rate.

and zero means no limit. The default value is no-limit.

and zero means no limit. The default value is no-limit. Egress rate limit­ing has an effect on all types of packets, including unicast, multicast, and
broadcast packets.

Rate Control Description

Apply Click Apply to apply the settings.

Note: You must Save the settings (Page 137), if you want to maintain

these settings if the RocketLinx ES7528 is powered off.

Storm Control

The Storm Control is similar to Rate Control. Rate Control filters all the traffic over the threshold you input by the user
interface. Storm Control allows you to define the rate for specific Packet Types.

Storm Control Description

Broadcast To enable or disable broadcast storm control on this port.

Choose Enable/Disable to enable or disable the storm control of
specific port.

DLF To enable or disable destination lookup failure storm control on

this port.

Multicast To enable or disable multicast storm control on this port.

Rate (packet/sec) These columns allow you to manually assign the limit rate of the

port. The unit is packets per second. The limit range is from 1 to
262143 packet/sec, zero means no limit. The maximum available
value of Fast Ethernet interface is 148810, this is the maximum
packet number of the 100M throughput.

Port Trunking

Port Trunking

Port Trunking configuration allows you to group multiple Ethernet ports in parallel to increase link bandwidth. The aggregated
ports can be viewed as one physical port so that the bandwidth is higher than merely one single Ethernet port.The member
ports of the same trunk group can balance the loading and backup for each other. The Port Trunking feature is usually used
when you need higher bandwidth for the network backbone. This is an inexpensive way for you to transfer more data.

There are some different descriptions for the port trunking. Different manufacturers may use different descriptions for their
products, like Link Aggregation Group (LAG), Link Aggregation Control Protocol, Ethernet Trunk, or Ether Channel.

The aggregated ports can interconnect to the other switch, which also supports Port Trunking. Comtrol supports two types of
port trunking:

• Static Trunk

• 802.3ad

When the other end uses 802.3ad LACP, you should assign 802.3ad LACP to the trunk. When the other end uses non-802.3ad,
you can then use Static Trunk.

There are two pages for port trunking, Aggregation Setting and Aggregation Status.

Aggregation Setting

Aggregation Setting Description

Trunk Size The switch can support up to 8 trunk groups. Each trunk group can support up to 8 member

ports. Since the member ports should use the same speed/duplex, maximum groups for 100M
ports would be 7, and 3 for gigabit ports.

Group ID Group ID is the ID for the port trunking group. Ports with same group ID are in the same group.

Trunk Type Static or 802.3ad LACP. Each Trunk Group can only support Static or 802.3ad LACP. Choose

the type you need here. Non-active ports cannot be setup here.

Load Balance Type There are several load balance types based on dst-ip (Destination IP), dst-mac (Destination

MAC), src-dst-ip (Source and Destination IP), src-dst-mac (Source and Destination MAC), src­ip (Source IP), src-mac (Source MAC).

Aggregation Status

This page shows the status of port aggregation. Once the aggregation ports are negotiated, you will see the following status.

Aggregation Status Description

Group ID Displays Trunk 1 to Trunk 8 set up.

Type Static or LACP set up.

Aggregated Ports When LACP links, you can see the member ports in the Aggregated column.

Individual Ports When LACP is enabled, member ports of LACP group that are not connected to

the correct LACP member ports are displayed in the Individual column.

Link Down Ports When LACP is enabled, member ports of LACP group that are not linked up are

displayed in the Link Down column.

Load Balance There are several load balance types based on dst-ip (Destination IP), dst-mac

(Destination MAC), src-dst-ip (Source and Destination IP), src-dst-mac (Source
and Destination MAC), src-ip (Source IP), src-mac (Source MAC).

Power over Ethernet

Power over Ethernet

Power over Ethernet is one of the key features of RocketLinx ES7528. It is fully IEEE802.3af-2003 compliant, and supports
IEEE802.3at, including two-event and LLDP classification. The RocketLinx ES7528 supports up to 24-Port PoE injectors in
Port 1 to Port 24, each port with the ability to deliver 606 mA current.

The following commands are included in this section:

• Emergency Power Management

• PoE Control

• PD Status Detection on Page 60

• PoE Scheduling

• PoE Status

• Command Line for PoE Control

Emergency Power Management

The RocketLinx ES7528 provides dual 48VDC power inputs for providing

true network redundancy. An alarm relay output signals when a power input
fails or other critical events occur. To ensure reliable power delivery, other
advanced PoE power management features include individual port status
monitoring, emergency power management (three power supply indication
inputs for quick shutdown of ports according to pre-defined priority table in
cases where power supply failure occurs) and voltage/current monitoring
and regulation. Power management allows the RocketLinx ES7528 to
determine the exact power draw per port and to balance each port PoE
power output accordingly. This allows the switch to power higher and lower
wattage devices according to user-definable parameters such as maximum available power, port priority (critical, high, low),
and maximum allowable power per port. For the same level priority, the priority order is decided by port number. The port
number sequence is from high priority to low priority is 3-4-1-2-7-8-5-6-11-12-9-10-15-16-13-14-19-20-17-18-23-24-21-22­27-28-25-26.

You can configure the power budget of DC Power 1 and 2 by following the Web UI. The valid range of budget is 1 – 480
Watts. The default power budget of inside AC power supply is 300W.

PoE Control

In WiMax systems, Wireless applications, and high-end PoE applications, there are various types of PDs, for example, IEEE

802.3af, IEEE 802.3at two-event, IEEE 802.3at LLDP, and non-standard type. To be compatible with different PDs, the
RocketLinx ES7528 is designed with four powering modes, including IEEE 802.3af mode, IEEE 802.3at 2-event mode and,
IEEE 802.3at LLDP classification mode as well as forced powering mode to meet all of the PD types in the industry. As a
result, they can be flexibly used to deliver power for different PoE-enabled devices in various applications.

IEEE 802.3at LLDP provides smart power budget control behavior to fulfill the needs of higher end setups requiring exact
high power delivery. By using the ongoing dynamic re-negotiation function of the IEEE802.3at LLDP, the RocketLinx ES7528
can perform more intelligently by dynamically reallocating power to the PDs. The RocketLinx ES7528 implements the 2 event
and Link Layer Discovery Protocol (LLDP) PoE into the system for efficient power budget negotiation between PSE and PD
devices.

58 - RocketLinx ES7528 Industrial Managed PoE Rack Mount User Guide: 2000509 Rev. A Power over Ethernet

The following figure shows the Web UI interface for Power over Ethernet Control.

PoE Control

PoE Control Description

PoE System Use this column to Enable/Disable ports, or set it to scheduling control mode.

DC Power 1

The limitation of output power in watts. The range is 1- 480.
DC Power 2
Budget (W)

PoE Mode You can select Disable, Enable, or Schedule for the PoE mode for each port.

Powering Mode Use this mode to change the Powering Mode to one of the following:

• IEEE 802.3af

• 802.3at(LLDP)

• 802.3at(2-Event)

•Force

When the column is IEEE 802.3af, if and only if the PD follows IEEE

802.3af, then the RocketLinx ES7528 could deliver the power. If the

Powering mode is 802.3at(LLDP) or 802.3at(2-Event), the RocketLinx

ES7528 would deliver power to the PD that supports IEEE 802.3at

LLDP or 2-Event feature. If the Powering Mode changes to Force mode, once the PoE mode is

enabled, the port directly delivers the power even there is no Ethernet cable connected.

Note: Use caution when usi ng Force mode.

Power Budget
(W)

The Power Budget can limit the consumption of PoE and ensure the PoE port can get the pre-

allocated power budget. The range of Power Budget is 0.4 to 32 Watt. The maximum effective

power budget of 802.3af powering mode is 15.4 W even if the power budget is set to 32 W.

Power Priority Power Priority lets the PoE port with higher priority to deploy power under the limit power

budget. There are three priorities (Critical, High and Low).

The following graphic illustrates how to configure IEEE 802.3at LLDP. Assume the PD is ready for the configuration for IEEE

802.3at LLDP, you only need to confirm the RocketLinx ES7528 configuration.

For example, connect the port of the RocketLinx ES7528 to the PD (ex. Port 4), set PoE Mode is Enable and Powering Mode
is 802.3at(LLDP). When the RocketLinx ES7528 and the PD are ready to IEEE802.3at LLDP, IEEE 802.3at LLDP starts
operation. Refer to PoE Status

on Page 61, to see the PoE Status page.

PD Status Detection

The RocketLinx ES7528 delivers a useful function – PD Status Detection. This
provides automatic detection of a remote device powered by the RocketLinx
ES7528. If the remote system crashes or is unstable, the RocketLinx ES7528
performs a system reboot by turning off and on again to trigger the remote
device. The following figure shows the web configuration interface for Power
over Ethernet PD Status Detection.

Network Redundancy

Network Redundancy

It is critical for industrial applications that the network remains running at all times. The RocketLinx ES7528 supports:

• Standard Rapid Spanning Tree Protocol (STP and RSTP)

The RocketLinx ES7528 supports RSTP versions 802.1D-2004, 802.1D-1998 STP, and 802.1w RSTP.

• Redundant Ring

Redundant Ring features 0 ms for restore and about 5 ms for fail over for copper.

• Rapid Dual Homing (RDH)

Advanced RDH technology facilitates the RocketLinx ES7528 to connecting with a core managed switch easily and
conveniently. With RDH technology, you can also couple several Rapid Super Rings or RSTP groups together, which is
also known as Auto Ring Coupling.

The following commands are included in this group:

• RSTP

• Command Lines for RSTP

RSTP

If a switch has more than one path to a destination, it leads to
message loops that can generate broadcast storms and quickly
bog down a network.

The spanning tree was created to combat the negative effects
of message loops in switched networks. A spanning tree uses a
spanning tree algorithm (STA) to automatically sense whether
a switch has more than one way to communicate with a node.
It then selects the best path (primary), and blocks the other
paths. It also keeps track of the blocked paths in case the
primary path fails. Spanning Tree Protocol (STP) introduced a
standard method to accomplish this. It is specified in IEEE

802.1D-1998. Later, Rapid Spanning Tree Protocol (RSTP)
was adopted and represents the evolution of STP, providing
much faster spanning tree convergence after a topology
change. This is specified in IEEE 802.1w. In 2004, 802.1w is
included into the 802.1D-2004 version. This switch supports
both RSTP and STP (all switches that support RSTP are also
backward compatible with switches that support only
STP).This page allows you to enable/disable RSTP, configure
the global setting and port settings.

Network Redundancy RocketLinx ES7528 Industrial Managed PoE Rack Mount User Guide: 2000509 Rev. A - 69

RSTP

Rapid Spanning

Tree Protocol

Description

RSTP You must first Enable STP/RSTP mode, before configuring any related parameters. Parameter settings

required for both STP and RSTP are the same. 802.1d refers to STP mode, while 802.1w refers to faster
RSTP mode.

Bridge Configuration

Priority (0-61440) RSTP uses bridge ID to determine the root bridge, the bridge with the highest bridge ID becomes the

root bridge. The bridge ID is composed of bridge priority and bridge MAC address. The bridge with the
highest priority becomes the highest bridge ID. If all the bridge IDs have the same priority, the bridge
with the lowest MAC address then becomes the root bridge.

Note: The bridge priority value must be in multiples of 4,096. A device with a lower number has a

higher bridge priority. Ex: 4096 is higher than 32,768.

Max Age (6-40) Enter a value from 6 to 40 seconds here. This value represents the time that a bridge waits without

receiving Spanning Tree Protocol configuration messages before attempting to reconfigure.
If the RocketLinx ES7528 is not the root bridge, and if it has not received a hello message from the root
bridge in an amount of time equal to Max Age, then the RocketLinx ES7528 reconfigures itself as a root
bridge. Once two or more devices on the network are recognized as a root bridge, the devices
renegotiate to set up a new spanning tree topology.

Hello Time (1-10) Enter a value from 1 to 10 seconds here. This is a periodic timer that drives the switch to send out Bridge

protocol data unit (BPDU) packet to check current STP status. The root bridge of the spanning tree
topology periodically sends out a “hello” message to other devices on the network to check if the
topology is “healthy”. The “hello time” is the amount of time the root has waited during sending hello
messages.
BPDUs are data messages that are exchanged across the switches within an extended LAN that uses a
spanning tree protocol topology. BPDU packets contain information on ports, addresses, priorities and
costs and ensure that the data ends up where it was intended to go. BPDU messages are exchanged
across bridges to detect loops in a network topology. The loops are then removed by shutting down
selected bridge interfaces and placing redundant switch ports in a backup, or blocked, state.

Forward Delay
Time (4-30)

Enter a value between 4 and 30 seconds. This value is the time that a port waits before changing from
Spanning Tree Protocol learning and listening states to forwarding state. This is the amount of time the
RocketLinx ES7528 waits before checking to see if it should be changed to a different state.

Note: You must observe the following rule to configure Hell o Time, Forwarding Delay, and Max Age parameters.

2 × (Forward Delay Time – 1 sec) ≥ Max Age Time ≥ 2 × (Hello Time value + 1 sec)

Port Configuration

Admin Path Cost Enter a number between 1 and 200,000,000. This value represents the cost of the path to the other bridge

from the transmitting bridge at the specified port.

Priority Enter a value between 0 and 240, using multiples of 16. This is the value that decides which port should

be blocked by priority in a LAN.

Admin P2P Some of the rapid state transitions that are possible within RSTP depend upon whether the port of

concern can only be connected to another bridge (that is, it is served by a point-to-point LAN segment),
or if it can be connected to two or more bridges (i.e, it is served by a shared-medium LAN segment).

This function allows P2P status of the link to be manipulated administratively. Auto means to auto
select P2P or Share mode. P2P means P2P is enabled, while Share means P2P is disabled.

Admin Edge A port directly connected to the end stations cannot create a bridging loop in the network. To configure

this port as an edge port, set the port to the Enable state. When the non-bridge device connects an admin

edge port, this port is in a blocking state and turns to a forwarding state in 4 seconds.

Redundant Ring

RSTP Information Description

Port Priority Decide which port should be blocked by priority in your LAN. Range is 0 through 240 in increments

of 16.

Oper P2P Some of the rapid state transactions that are possible within RSTP are dependent upon whether the

Port in question can be concerned to exactly one other Bridge (ie., it is served by a point-to-point
LAN segment), or can be connected to two or more Bridges (i.e., it is served by a shared medium
LAN segment).

Oper Edge Present in implementations that support the identification of edge ports. All ports directly connected

to end stations cannot create bridging loops in the network and can thus directly transition to for­warding, skipping the listening and learning stages. When the non-bridge device connects an admin
edge port, this port is in blocking state and turn to forwarding state in 4 seconds.

Redundant Ring

The most common industrial network redundancy is to form a ring or loop. Typically, the managed switches are connected in
series and the last switch is connected back to the first one. In such connection, you can implement Redundant Ring
technology.

Redundant Ring Description

New Ring To create a Redundant Ring enter the Ring ID, which has range from 0 to 31. If the name field is left

Redundant Ring Description

Redundant Ring

Device Priority The switch with highest priority (highest value) is automatically selected as the Ring Master. When one

of the ring ports on this switch becomes a forwarding port and the other one becomes a blocking port.
If all of the switches have the same priority, the switch with the highest MAC address is selected as the
Ring Master.

Ring Port1 In a Rapid Super Ring environment, you should have two Ring Ports. Whether this switch is a Ring

Master or not. When configuring Rapid Super Rings, two ports should be selected to be Ring Ports. For
a Ring Master, one of the ring ports becomes the forwarding port and the other one becomes the
blocking port.

Path Cost Change the Path Cost of Ring Port1, if this switch is the Ring Master of a Ring, then it determines the

blocking port. The Port with higher Path Cost in the two ring ports becomes the blocking port, If the
Path Cost is the same, the port with larger port number becomes the blocking port.

Ring Port2 Assign another port for ring connection.

Path Cost Change the Path Cost of Ring Port2.

Rapid Dual Homing Rapid Dual Homing is an important feature of Rapid Super Ring redundancy technology. When you

want to connect multiple RSR or form redundant topology with other vendors, RDH allows you to
have a maximum of seven multiple links for redundancy without any problem.

In Rapid Dual Homing, you do not need to configure a specific port to connect to other protocol. The
Rapid Dual Homing selects the fastest link for the primary link and blocks all the other links to avoid a
loop. If the primary link failed, Rapid Dual Homing automatically forwards the secondary link for a
network redundant. If there are more connections, they are standby links and are recovered if both
primary and secondary links are broken.

Ring status To enable/disable the Ring. Please remember to enable the ring after you add it.

MultiRing This technology allows you to aggregate multiple rings within one switch. Create multiple ring IDs and

assign different ring Port1 and Port2 to each ring. Thus, the switch can have up to 14 rings in one
RocketLinx ES7528.

When implementing MultiRing, remember that the different rings can NOT use the same ring ID. The
other settings are the same as the above description. Technically, the maximum ring volume the
MultiRing support is up to 16 rings. Due to the power volume limitation, RocketLinx ES7528 supports
up to 14 rings.

Trunk Ring The MultiRing technology is part of the Redundant Ring technology which combines Redundant Ring

with the port trunking technology. After multiple ports are aggregated, so-called port trunking, the
Trunk ID can be one of the port IDs of the Redundant Ring technology. Configure the port trunking
first then configure the Trunk Ring in the managed switch.

Apply Click Apply to apply the settings.

Note: You must Save the settings (Page 137), if you want to maintain these settings if the RocketLinx

ES7528 is powered off.

VLAN

VLAN

A Virtual LAN (VLAN) is a logical grouping of nodes for the purpose of limiting a broadcast domain to specific members of a
group without physically grouping the members. The VLAN allows you to isolate network traffic so that only members of the
VLAN could receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is the logical
equivalent of physically reconnecting a group of network devices to another layer 2 switch, without actually disconnecting
these devices from their original switches.

The RocketLinx ES7528 supports 802.1Q VLAN, which is also known as Tag-Based VLAN. This Tag-Based VLAN allows a
VLAN to be created across different switches. IEEE 802.1Q tag-based VLAN makes use of VLAN control information stored
in a VLAN header attached to IEEE 802.3 packet frames. This tag contains a VLAN Identifier (VID) that indicates which
VLAN a frame belongs to. Since each switch only has to check a frame’s tag, without the need to dissect the contents of the
frame, this also saves a lot of computing resources within the switch.

The following figure displays an 802.1Q VLAN.

VLAN Configuration group enables you to Add/Remove a VLAN, configure port Ingress/Egress parameters, and view VLAN

VLAN Port Configuration

VLAN Port Configuration

VLAN Port Configuration allows you to set up VLAN port parameters to a specific port. These parameters include PVID,
Accept Frame Type and Ingress Filtering.

VLAN Port

Configuration

Description

PVID Enter the port VLAN ID (PVID). The PVID allows the switches to identify

which port belongs to which VLAN. To keep things simple, it is
recommended that PVID is equivalent to VLAN IDs. The values of PVIDs
are from 0 to 4,095, but 0 and 4,095 are reserved. 1 is the default value. 2 to
4,094 are valid and available in this column. Type the PVID you want to
configure.

Accept Frame Type This column defines the accepted frame type of the port. There are two

modes you can select, Admit All and Tag Only. Admit All mode means that
the port can accept both tagged and untagged packets. Tag Only mode means
that the port can only accept tagged packets.

Ingress Filtering Ingress filtering instructs the VLAN engine to filter out undesired traffic on a

port. When Ingress Filtering is enabled, the port checks whether the incoming
frames belong to the VLAN they claimed or not. The port then determines if
the frames can be processed or not. For example, if a tagged frame from
Engineer VLAN is received, and Ingress Filtering is enabled, the switch
determines if the port is on the Engineer VLAN’s Egress list. If it is, the
frame can be processed. If it is not, the frame is dropped.

Use this page to assign the Management VLAN, create the static VLAN, and assign the Egress rule for the member ports of the
VLAN.

VLAN Configuration Description

Management VLAN IDThe RocketLinx ES7528 supports management VLAN. The management VLAN ID is the VLAN

ID of the CPU interface so that only member ports of the management VLAN can ping and access
the switch. The default management VLAN ID is 1.

Click Apply after you enter the VLAN ID.

Static VLAN You can assign a VLAN ID and VLAN Name for new VLAN.

• VLAN ID: This is used by the switch to identify different VLANs. A valid VLAN ID is

between 1 and 4,094, 1 is the default VLAN.

• VLAN Name: This is a reference for the network administrator to identify different VLANs.

The VLAN name may up to 12 characters in length. If you do not provide a VLAN name, the
system automatically assigns a VLAN name for this VLAN. The rule is VLAN (VLAN ID).

Click Add to create a new VLAN. The new VLAN displays in the Static VLAN Configuration

table. After creating the VLAN, the status of the VLAN remains Unused, until you add ports to
the VLAN.

Note: Before changing the management VLAN ID by web or Telnet, remember that the port

attached by the administrator should be the member port of the management VLAN;
otherwise the administrator cannot access the switch through the network. The
RocketLinx ES7528 supports a maximum of 64 VLANs.

GVRP Configuration

GVRP Configuration

GVRP allows you to set-up VLANs automatically rather than manual configuration on every port of every switch in the
network. GVRP conforms to the IEEE 802.1Q specification. This defines a method of tagging frames with VLAN
configuration data that allows network devices to dynamically exchange VLAN configuration information with other devices.

GARP (Generic Attribute Registration Protocol), a protocol that defines procedures by which end stations and switches in a
local area network (LAN) can register and de-register attributes, such as identifiers or addresses, with each other. Every end
station and switch thus has a current record of all the other end stations and switches that can be reached. GVRP, like GARP,
eliminates unnecessary network traffic by preventing attempts to transmit information to unregistered users. In addition, it is
necessary to manually configure only one switch and all the other switches will be configured accordingly.

GVRP Configuration Description

GVRP Protocol Allows you to Enable/Disable GVRP globally.
State After enabling GVRP globally, you can still Enable/Disable GVRP by port.

Join Timer Controls the interval of sending the GVRP Join BPDU. An instance of this

timer is required on a per-Port, per-GARP Participant basis.

Leave Timer Controls the time to release the GVRP reservation after having received the

GVRP Leave BPDU. An instance of the timer is required for each state
machine that is in the LV state.

Leave All Timer Controls the period to initiate the garbage collection of registered VLAN.

The timer is required on a per-Port, per-GARP Participant basis.

• -- No VLAN setting.

• T A Trunk Link is a LAN segment used for multiplexing VLANs

between VLAN bridges. All the devices that connect to a Trunk Link
must be 802.1Q VLAN-aware, which sends and receives frames with

802.1Q tags.

• U An Access Link is a LAN segment used to multiplex one or more

802.1Q VLAN-unaware devices into a Port of a VLAN Bridge. Devices
that are connected to an Access Link sends and receives frames without

802.1Q tagging, which is the identification of the VLAN it belongs to.

After creating the VLAN, the status of this VLAN remains in Unused status until you add ports to the VLAN.

Traffic Prioritization

Traffic Prioritization

Quality of Service (QoS) provides a traffic prioritization mechanism which allows you to deliver better service to certain
flows. QoS can also help to alleviate congestion problems and ensure high-priority traffic is delivered first. This section allows
you to configure Traffic Prioritization settings for each port with regard to setting priorities.

RocketLinx ES7528 QOS supports four physical queues, weighted fair queuing (WRR) and Strict Priority scheme, that follows
the 802.1p COS tag and IPv4 TOS/DiffServ information to prioritize the traffic of your industrial network.

The following commands are included in this group:

• QoS Setting

• CoS-Queue Mapping

• DSCP-Queue Mapping

• CLI Commands of the Traffic Prioritization on Page 92

88 - RocketLinx ES7528 Industrial Managed PoE Rack Mount User Guide: 2000509 Rev. A Traffic Prioritization

QoS Setting

Use this subsection to set up QoS settings for the RocketLinx ES7528.

QoS Setting

QoS Setting Description

Queue Scheduling

Use a Round
Robin scheme

Use a strict
priority scheme

Use Weighted
Round Robin
scheme

The Round Robin scheme means all the priority has the same privilege, the traffic is forward cyclic
from highest to lowest.

Packets with higher priority in the queue are always processed first, except that there is no packet with
higher priority.

This scheme allows you to assign new weight ratio for each class. The 10 is the highest ratio. The ratio
of each class is:

Wx / W0 + W1 + W2 + W3 + W4 + W5 + W6 + W7 (Total volume of Queue 0-7)

Port Setting

Priority Indicates the default port priority value for untagged or priority-tagged frames. When the RocketLinx

ES7528 receives the frames, the RocketLinx ES7528 attaches the value to the CoS field of the

incoming VLAN-tagged packets. You can enable 0,1,2,3,4,5,6 or 7 to the port.
Default priority type is COS. The system provides default COS-Queue table to which you can refer for

the next command.

Apply Click Apply to apply the settings.

Note: You must Save the settings (Page 137), if you want to maintain these settings if the RocketLinx

ES7528 is powered off.

QoS Setting RocketLinx ES7528 Industrial Managed PoE Rack Mount User Guide: 2000509 Rev. A - 89

CoS-Queue Mapping

CoS-Queue Mapping

Use this page to change the CoS values into a Physical Queue mapping table. Since the switch fabric of the RocketLinx
ES7528 only supports eight queues, Lowest, Low, Middle and High. You should therefore assign how to map CoS value to the
level of the physical queue.

Class of service (CoS) is a 3 bit field within a layer two Ethernet frame header defined by IEEE 802.1p when using 802.1Q

tagging. The field specifies a priority value of between 0 and 7 inclusive that can be used by Quality of Service (QoS)
disciplines to differentiate traffic.

While CoS operates only on Ethernet at the data link layer, other QoS mechanisms (such as DiffServ) operate at the network
layer and higher. Others operate on other physical layers. Although 802.1Q tagging must be enabled to communicate priority
information from switch to switch, some switches use CoS to internally classify traffic for QoS purposes.

Differentiated Services (DiffServ) is a model where traffic is treated by intermediate systems with relative priorities based on
the type of services (ToS) field. Defined in RFC2474 and RFC2475, the DiffServ standard supersedes the original specification
for defining packet priority described in RFC791. DiffServ increases the number of definable priority levels by reallocating
bits of an IP packet for priority marking. The DiffServ architecture defines the DiffServ field, which supersedes the ToS field
in IPv4 to make per-hop behavior (PHB) decisions about packet classification and traffic conditioning functions, such as;
metering, marking, shaping, and policing.

Multicast Filtering

Multicast Filtering

For multicast filtering, the RocketLinx ES7528 uses IGMP (Internet Group Management Protocol) Snooping technology.
IGMP is an internet protocol that provides a way for internet device to report its multicast group membership to adjacent
routers. Multicasting allows one computer on the internet to send data to a multitude of other computers that have identified
themselves as being interested in receiving the originating computers data.

Multicasting is useful for such applications as updating the address books of mobile computer users in the field, sending out
newsletters to a distribution list, and broadcasting streaming media to an audience that has tuned into the event by setting up
multicast group membership.

In effect, IGMP Snooping manages multicast traffic by making use of switches, routers, and hosts that support IGMP. Enabling
IGMP Snooping allows the ports to detect IGMP queries, report packets, and manage multicast traffic through the switch.
IGMP has three fundamental types of messages, as shown in the following table.

Message Description

Query A message sent from the querier (an IGMP router or a switch) that asks for a

Report A message sent by a host to the querier to indicate that the host wants to be or is

You can enable IGMP Snooping and IGMP Query functions. This section illustrates the information of the IGMP Snooping

function, including different multicast groups’ VID and member ports, and IP multicast addresses that range from 224.0.0.0 to

239.255.255.255.

IGMP Snooping

IGMP Snooping

Use this page to enable the IGMP Snooping feature, assign IGMP Snooping for specific VLANs, and view the IGMP
Snooping table from a dynamic learnt or static that you provide. The RocketLinx ES7528 supports IGMP snooping V1/V2/V3
automatically and IGMP query V1/V2.

IGMP Snooping Description

IGMP Snooping You can select Enable or Disable. After enabling IGMP Snooping, you can

then enable IGMP Snooping for specific VLAN.

You can Enable IGMP Snooping for some VLANs so that some of the

VLANs support IGMP Snooping and others will not.
To assign IGMP Snooping to VLAN, click the check box of the VLAN ID or

click the Select All check box for all VLANs and then click Enable. You can
also Disable IGMP Snooping for certain VLANs using the same method.

IGMP Snooping Table This table displays the multicast group IP address, VLAN ID it belongs to,

and member ports of the multicast group. The RocketLinx ES7528 supports

256 multicast groups. Click Reload to refresh the table.

IGMP has three fundamental types of messages as follows:

Message Description

Query A message sent from the querier (IGMP router or switch) asking for a

response from each host belonging to the multicast group.

Report A message sent by a host to the querier to indicate that the host wants to be or

is a member of a given group indicated in the report message.

Leave Group A message sent by a host to the querier to indicate that the host has quit being

a member of a specific multicast group.

IGMP Query

Use this page to configure the IGMP Query feature. Since the
RocketLinx ES7528 can only be configured by member ports of the
management VLAN, the IGMP Query can only be enabled on the
management VLAN. If you want to run IGMP Snooping feature in
several VLANs, first check to see whether each VLAN has its own
IGMP Querier.

The IGMP querier periodically sends query packets to all end-stations
on the LANs or VLANs that are connected to it. For networks with more
than one IGMP querier, a switch with the lowest IP address becomes the
IGMP querier.

IGMP Query Description

Version Select Version 1, Version 2 or Disable. Version 1 means IGMP V1 General

Query and Version 2 means IGMP V2 General Query. The query is
forwarded to all multicast groups in the VLAN. Disable allows you to disable
IGMP Query.

Query Interval(s) The period of query (seconds) sent by querier. Enter a number between 1 and

65,535.

Query Maximum
Response Time

Apply Click Apply to apply the settings.

The span querier detect (seconds) to confirm there are no more directly
connected group members on a LAN. Enter a number between 1 and 25.

IGMP Query

Note: You must Save the settings (Page 137), if you want to maintain these

settings if the RocketLinx ES7528 is powered off.

Unknown Multicast

This page allows you to decide how to forward the unknown multicast traffic. After enabling
IGMP Snooping, the known multicast can be filtered by IGMP Snooping mechanism and
forwarded to the member ports of known multicast groups. The other multicast streams that are
not learnt is a so-called unknown multicast, the switch decides how to forward them based on the
setting of this page.

UnKnown Multicast Description

Send to Query Ports The unknown multicast is sent to the Query ports. The Query port

means the port received the IGMP Query packets. It is usually the
uplink port of the switch.

Send to All Ports The unknown multicast is flooded on all ports even if they are not

member ports of the groups.

Discard The unknown multicast is discarded. Non-member ports will not

receive the unknown multicast streams.

Apply Click Apply to apply the settings.

GMRP Configuration

GMRP Configuration

GARP Multicast Registration Protocol (GMRP) is a Generic Registration Protocol
(GARP) application that provides a multicast traffic management facility at layer 2
similar to what IGMP provides at layer 3. GMRP and GARP are industry-standard
protocols first introduced as part of IEEE 802.1D.

GMRP

Description

GMRP Protocol Enable/Disable GMRP protocol.

Port The port number.

State The state of the GMRP operation on this port. The value

enabled indicates that the GMRP is enabled on this port as
long as the GMRP protocol is also enabled for this device.
When disabled, but the GMRP protocol is still enable for the
device, GMRP is disabled on this port.
