Chapter 1 Operation of Web-based Management

Initial
Configuration

This chapter instructs you how to configure and manage the GTP-2880
through the web user interface. With this facility, you can easily access
and monitor through any one port of the switch all the status of the switch,
including MIBs status, each port activity, Spanning tree status, port
aggregation status, multicast traffic, VLAN and priority status, even illegal
access record and so on.

The default values of the GTP-2880 are listed in the table below:

After the GTP-2880 has been finished configuration the it interface, you
can browse it. For instance, type http://192.168.1.1 in the address row
in a browser, it will show the following screen and ask you inputting
username and password in order to login and access authentication.

The default username is “admin” and password is empty. For the first
time to use, please enter the default username and password, and then
click the <Login> button. The login process now is completed. In this
login menu, you have to input the complete username and password
respectively, the switch will not give you a shortcut to username

automatically. This looks inconvenient, but safer.

In the switch, it supports a simple user management function allowing
only one administrator to configure the system at the same time. If there
are two or more users using administrator’s identity, it will allow the only
one who logins first to configure the system. The rest of users, even with

administrator’s identity, can only monitor the system. For those who have
no administrator’s identity, can only monitor the system. There are only a

maximum of three users able to login simultaneously in the switch.

CONNECTING
NETWORK

DEVICES

The switch is designed to be connected to 10, 100 or
1000Mbps network cards in PCs and servers, as well
as to other switches and hubs. It may also be
connected to remote devices using optional SFP

transceivers.

TWISTED-PAIR
DEVICES

Each device requires an unshielded twisted-pair (UTP)
cable with RJ-45 connectors at both ends. Use
Category 5, 5e or 6 cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX
connections

CABLING
GUIDELINES

The RJ-45 ports on the switch that support automatic
MDI/MDI-X pin-out configuration, so you can use
standard straight-through twisted-pair cables to
connect to any other network device (PCs, servers,
switches, routers, or hubs).

C

AUTION

:

Do not plug a phone jack connector into an RJ-45 port.
This will damage the switch. Use only twisted-pair cables with
RJ-45 connectors that conform to FCC standards.

See Appendix B for further information on cabling.

CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES

Step1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

Figure 16: Making Twisted-Pair Connections

5

NOTE: Avoid using flow control on a port connected to a hub

unless it is actually required to solve a problem. Otherwise
back pressure jamming signals may degrade overall
performance for the segment attached to the hub.

Wall

Step2. If the device is a network card and the switch is in the wiring closet, attach the

other end of the cable segment to a modular wall outlet that is connected to

the wiring closet. (See the section “Network Wiring Connections.”) Otherwise,

attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

Step3. As each connection is made, the Link LED (on the switch) corresponding to

each port will light green (1000 Mbps) or amber (100 Mbps) to indicate that
the connection is valid.

NETWORK WIRING CONNECTIONS

Today, the punch-down block is an integral part of many of the newer equipment racks.
It is actually part of the patch panel. Instructions for making connections in the wiring
closet with this type of equipment follows.

Step1. Attach one end of a patch cable to an available port on the switch, and the

other end to the patch panel.

Step2. If not already in place, attach one end of a cable segment to the back of the

patch panel where the punch-down block is located, and the other end to a
modular wall outlet.

Step3. Label the cables to simplify future troubleshooting. See “Cable Labeling and

Connection Records” on page 29

2-4 IP

IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an
internet network.

IP is a "best effort" system, which means that no packet of information sent over is assured to
reach its destination in the same condition it was sent. Each device connected to a Local Area
Network (LAN) or Wide Area Network (WAN) is given an Internet Protocol address, and this
IP address is used to identify the device uniquely among all other devices connected to the
extended network.

The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol
addresses allowing for in excess of four billion unique addresses. This number is reduced
drastically by the practice of webmasters taking addresses in large blocks, the bulk of which
remain unused. There is a rather substantial movement to adopt a new version of the Internet
Protocol, IPv6, which would have 128-bits Internet Protocol addresses. This number can be
represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the
protocol of choice for most of the Internet.

2-4.1 IPV4

The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually
configure an address, you need to change the switch's default settings to values that are
compatible with your network. You may also need to establish a default gateway between the
switch and management stations that exist on another network segment.

2-6 SNMP

Any Network Management System (NMS) running the Simple Network Management Protocol
(SNMP) can manage the Managed devices equipped with SNMP agent, provided that the
Management Information Base (MIB) is installed correctly on the managed devices. The
SNMP is a protocol that is used to govern the transfer of information between SNMP manager
and agent and traverses the Object Identity (OID) of the management Information Base (MIB),
described in the form of SMI syntax. SNMP agent is running on the switch to response the
request issued by SNMP manager.

Basically, it is passive except issuing the trap information. The switch supports a switch to turn
on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will be started up.
All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager. If the
field SNMP is set “Disable”, SNMP agent will be de-activated, the related Community Name,
Trap Host IP Address, Trap and all MIB counters will be ignored.

2-6.1 System

This section describes how to configure SNMP System on the switch. This function is used
to configure SNMP settings, community name, trap host and public traps as well as the
throttle of SNMP. A SNMP manager must pass the authentication by identifying both
community names, then it can access the MIB information of the target device. So, both
parties must have the same community name. Once completing the setting, click <Apply>
button, the setting takes effect.

3-2 ACL

The GTP-2880 switch access control list (ACL) is probably the most commonly used object in
the IOS. It is used for packet filtering but also for selecting types of traffic to be analyzed,
forwarded, or influenced in some way.The ACLs are divided into EtherTypes. IPv4, ARP
protocol, MAC and VLAN parameters etc. Here we will just go over the standard and
extended access lists for TCP/IP. As you create ACEs for ingress classification, you can
assign a policy for each port, the policy number is 1-8, however, each policy can be applied to
any port. This makes it very easy to determine what type of ACL policy you will be working
with.

The section describes how to configure Access Control List rule. An Access Control List (ACL)
is a sequential list of permit or deny conditions that apply to IP addresses, MAC addresses, or
other more specific criteria. This switch tests ingress packets against the conditions in an ACL
one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as
soon as it matches a deny rule. If no rules match, the frame is accepted. Other actions can
also be invoked when a matching packet is found, including rate limiting, copying matching
packets to another port or to the system log, or shutting down a port.

3-3 Aggregation

The Aggregation is used to configure the settings of Link Aggregation. You can bundle more
than one port with the same speed, full duplex and the same MAC to be a single logical port,
thus the logical port aggregates the bandwidth of these ports. This means you can apply your

current Ethernet equipment’s to build the bandwidth aggregation. For example, if there are

three Fast Ethernet ports aggregated in a logical port, then this logical port has bandwidth
three times as high as a single Fast Ethernet port has.

3-3.1 Static Trunk

The Aggregation Configuration is used to configure the settings of Link Aggregation. You can
bundle more than one port with the same speed, full duplex and the same MAC to be a single
logical port, thus the logical port aggregates the bandwidth of these ports. This means you
can apply your current Ethernet equipment’s to build the bandwidth aggregation.

3-3.1.1 Static Trunk

Ports using Static Trunk as their trunk method can choose their unique Static GroupID to form
a logic “trunked port”. The benefit of using Static Trunk method is that a port can immediately
become a member of a trunk group without any handshaking with its peer port. This is also a
disadvantage because the peer ports of your static trunk group may not know that they should
be aggregate together to form a “logic trunked port”. Using Static Trunk on both end of a link
is strongly recommended. Please also note that low speed links will stay in “not ready” state
when using static trunk to aggregate with high speed links.

Web Interface

3-3.2 LACP

Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad specification) as their
trunking method can choose their unique LACP GroupID to form a logic “trunked port”. The
benefit of using LACP is that a port makes an agreement with its peer port before it becomes a
ready member of a “trunk group” (also called aggregator). LACP is safer than the other trunking
method - static trunk.

3-3.2.1 Configuration

This page allows the user to inspect the current LACP port configurations, and possibly
change them as well An LACP trunk group with more than one ready member-ports is a “real
trunked” group. An LACP trunk group with only one or less than one ready member-ports is
not a “real trunked” group.

3-4 Spanning Tree

The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to
provide backup links between switches, bridges or routers. This allows the switch to interact
with other bridging devices (that is, an STP-compliant switch, bridge or router) in your network
to ensure that only one route exists between any two stations on the network, and provide
backup links which automatically take over when a primary link goes down.

STP - STP uses a distributed algorithm to select a bridging device (STP- compliant switch,
bridge or router) that serves as the root of the spanning tree network. It selects a root port on
each bridging device (except for the root device) which incurs the lowest path cost when
forwarding a packet from that device to the root device. Then it selects a designated bridging
device from each LAN which incurs the lowest path cost when forwarding a packet from that
LAN to the root device. All ports connected to designated bridging devices are assigned as
designated ports. After determining the lowest cost spanning tree, it enables all root ports and
designated ports, and disables all other ports. Network packets are therefore only forwarded
between root ports and designated ports, eliminating any possible network loops.

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 (Maximum Age), the bridge assumes that the link to the Root
Bridge is down. This bridge will then initiate negotiations with other bridges to reconfigure the
network to reestablish a valid network topology.

Parameter description:

Basic Settings

 Protocol Version :

The STP protocol version setting. Valid values are STP, RSTP and MSTP.

 Bridge Priority :

Controls the bridge priority. Lower numeric values have better priority. The
bridge priority plus the MSTI instance number, concatenated with the 6-byte
MAC address of the switch forms a Bridge Identifier. For MSTP operation, this is
the priority of the CIST. Otherwise, this is the priority of the STP/RSTP bridge.

 Forward Delay :

The delay used by STP Bridges to transit Root and Designated Ports to
Forwarding (used in STP compatible mode). Valid values are in the range 4 to
30 seconds.

 Max Age :

The maximum age of the information transmitted by the Bridge when it is the
Root Bridge. Valid values are in the range 6 to 40 seconds, and MaxAge must
be <= (FwdDelay-1)*2.

 Maximum Hop Count :

This defines the initial value of remaining Hops for MSTI information generated
at the boundary of an MSTI region. It defines how many bridges a root bridge
can distribute its BPDU information to. Valid values are in the range 6 to 40
hops.

 Transmit Hold Count :

The number of BPDU's a bridge port can send per second. When exceeded,
transmission of the next BPDU will be delayed. Valid values are in the range 1
to 10 BPDU's per second.

Advanced Settings

 Edge Port BPDU Filtering :

Control whether a port explicitly configured as Edge will transmit and receive
BPDUs.

61

 Edge Port BPDU Guard :

reception of a BPDU. The port will enter the error-disabled state, and will be
removed from the active topology.

 Port Error Recovery :

Control whether a port in the error-disabled state automatically will be enabled
after a certain time. If recovery is not enabled, ports have to be disabled and
re-enabled for normal STP operation. The condition is also cleared by a system
reboot.

 Port Error Recovery Timeout :

The time to pass before a port in the error-disabled state can be enabled. Valid
values are between 30 and 86400 seconds (24 hours).

 STP Enabled :

Controls whether STP is enabled on this switch port.

 Path Cost :

Controls the path cost incurred by the port. The Auto setting will set the path
cost as appropriate by the physical link speed, using the 802.1D recommended
values. Using the Specific setting, a user-defined value can be entered. The
path cost is used when establishing the active topology of the network. Lower

66

path cost ports are chosen as forwarding ports in favour of higher path cost
ports. Valid values are in the range 1 to 200000000.

 Priority :

Controls the port priority. This can be used to control priority of ports having
identical port cost. (See above).

 operEdge (state flag) :

Operational flag describing whether the port is connecting directly to edge
devices. (No Bridges attached). Transition to the forwarding state is faster for
edge ports (having operEdge true) than for other ports.The value of this flag is
based on AdminEdge and AutoEdge fields. This flag is displayed as Edge in
Monitor->Spanning Tree -> STP Detailed Bridge Status.

 AdminEdge :

Controls whether the operEdge flag should start as set or cleared. (The initial
operEdge state when a port is initialized).

 AutoEdge :

Controls whether the bridge should enable automatic edge detection on the
bridge port. This allows operEdge to be derived from whether BPDU's are
received on the port or not.

 Restricted Role :

If enabled, causes the port not to be selected as Root Port for the CIST or any
MSTI, even if it has the best spanning tree priority vector. Such a port will be
selected as an Alternate Port after the Root Port has been selected. If set, it
can cause lack of spanning tree connectivity. It can be set by a network
administrator to prevent bridges external to a core region of the network
influence the spanning tree active topology, possibly because those bridges are
not under the full control of the administrator. This feature is also known as
Root Guard.

 Restricted TCN :

If enabled, causes the port not to propagate received topology change
notifications and topology changes to other ports. If set it can cause temporary
loss of connectivity after changes in a spanning tree's active topology as a
result of persistently incorrect learned station location information. It is set by
a network administrator to prevent bridges external to a core region of the
network, causing address flushing in that region, possibly because those
bridges are not under the full control of the administrator or the physical link
state of the attached LANs transits frequently.

 BPDU Guard :

If enabled, causes the port to disable itself upon receiving valid BPDU's.
Contrary to the similar bridge setting, the port Edge status does not affect this
setting. A port entering error-disabled state due to this setting is subject to the
bridge Port Error Recovery setting as well.

 Point to Point

Controls whether the port connects to a point-to-point LAN rather than to a
shared medium. This can be automatically determined, or forced either true or
false. Transition to the forwarding state is faster for point-to-point LANs than
for shared media.

3-5 IGMP Snooping

The function, is used to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoids wasting the bandwidth while IP multicast packets are
running over the network. This is because a switch that does not support IGMP or IGMP
Snooping can not tell the multicast packet from the broadcast packet, so it can only treat them
all as the broadcast packet. Without IGMP Snooping, the multicast packet forwarding function
is plain and nothing is different from broadcast packet.

A switch supported IGMP Snooping with the functions of query, report and leave, a type of
packet exchanged between IP Multicast Router/Switch and IP Multicast Host, can update the
information of the Multicast table when a member (port) joins or leaves an IP Multicast
Destination Address. With this function, once a switch receives an IP multicast packet, it will
forward the packet to the members who joined in a specified IP multicast group before.

The packets will be discarded by the IGMP Snooping if the user transmits multicast packets to
the multicast group that had not been built up in advance. IGMP mode enables the switch to
issue IGMP function that you enable IGMP proxy or snooping on the switch, which connects
to a router closer to the root of the tree. This interface is the upstream interface. The router on
the upstream interface should be running IGMP.

3-5.3 Port Group Filtering

The section describes how to set the IGMP Port Group Filtering? With the IGMP filtering
feature, an user can exert this type of control. In some network Application environments, as
like the metropolitan or multiple-dwelling unit (MDU) installations, an user might want to
control the multicast groups to which a user on a switch port can belong. It allows the user to
control the distribution of multicast services, such as IP/TV, based on some type of
subscription or service plan.

With this feature, you can filter multicast joins on a per-port basis by configuring IP multicast
profiles and associating them with individual switch ports. An IGMP profile can contain one or
more multicast groups and specifies whether access to the group is permitted or denied. If an
IGMP profile denying access to a multicast group is applied to a switch port, the IGMP join
report requesting the stream of IP multicast traffic is dropped, and the port is not allowed to
receive IP multicast traffic from that group. If the filtering action permits access to the
multicast group, the IGMP report from the port is forwarded for normal processing.

IGMP filtering controls only IGMP membership join reports and has no relationship to the
function that directs the forwarding of IP multicast traffic.

3-5.6 IPv4 SSM information

Source Specific Multicast (SSM) is a datagram delivery model that best supports one-to-many
applications, also known as broadcast applications. SSM is a core network technology of IP
multicast targeted for audio and video broadcast application environments.

For the SSM delivery mode, an IP multicast receiver host must use IGMP Version 3 (IGMPv3)
to subscribe to channel (S, G). By subscribing to this channel, the receiver host is indicating
that it wants to receive IP multicast traffic sent by source host S to group G. The network will
deliver IP multicast packets from source host S to group G to all hosts in the network that
have subscribed to the channel (S, G).

SSM does not require group address allocation within the network, only within each source
host. Different applications running on the same source host must use different SSM groups.
Different applications running on different source hosts can arbitrarily reuse SSM group
addresses without causing any excess traffic on the network.

Addresses in the range 232.0.0.0/8 (232.0.0.0 to 232.255.255.255) are reserved for SSM by
IANA. In the switch, you can configure SSM for arbitrary IP multicast addresses also.

3-6 MLD Snooping

Curiously enough, a network node that acts as a source of IPv6 multicast traffic is only an
indirect participant in MLD snooping—it just provides multicast traffic, and MLD doesn’t
interact with it. (Note, however, that in an application like desktop conferencing a network
node may act as both a source and an MLD host; but MLD interacts with that node only in its
role as an MLD host.)

A source node creates multicast traffic by sending packets to a multicast address. In IPv6,

addresses with the first eight bits set (that is, “FF” as the first two characters of the address)

are multicast addresses, and any node that listens to such an address will receive the traffic
sent to that address. Application software running on the source and destination systems
cooperates to determine what multicast address to use. (Note that this is a function of the
application software, not of MLD.)

When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary
multicast traffic. If the switch receives multicast traffic destined for a given multicast address, it
forwards that traffic only to ports on the VLAN that have MLD hosts for that address. It drops
that traffic for ports on the VLAN that have no MLD hosts
