Product Description
The AT-3726XL and AT-3716XL are standalone, managed Ethernet
switches that provides 24 or 14 10Base-T ports and one built-in
10/100Base-TX port. All ports capable of full- or half-duplex with
auto-negotiation or manual configuration on all ports.
The AT-3714FXL provides 12 10Base-FL ports with one built-in
100Base-FX (SC). All ports manually configurable for half- or fullduplex.
All switches include a 100Base slot that can be configured with an
optional Media Dependent Adapter (MDA) for 10/100Base-TX,
100Base-FX (SC), 100Base-FX (MT-RJ) or 100Base-FX (VF-45). Figure
1-1 shows the switches with the optional AT-A10, AT-A11, AT-A20
and AT-A21 MDAs.
The switches are intended for connections to the desktop as well as
workgroup applications and implement direct high-speed server
and backbone connections. Full-duplex capability on all ports
eliminates collisions and provides up to 20 Mbps on the 10Base ports
and up to 200 Mbps of bandwidth on the 100Base ports to servers,
routers, and other switches. With built-in management, these
switches provide seamless SNMP-based management capability.

MAC Addressing
Store-and-
Forward Mode
Transmit Pacing
The switch has hardware base support with Internal Address Lookup
Engine (IALE) for static entries and self-learning of active MAC
addresses. The switch supports 2K MAC addresses in CAM.
With store-and-forward switching mode, network administrators can
optimize performance and enable full-error checking.
The store-and-forward mode works in the following way. First, as the
packet is being received, it is placed in a buffer and held there until
the entire packet is received. The packet is also being checked for
errors and is not forwarded unless the entire packet is error-free. This
mode is automatic when data is exchanged between 10Base and
100Base ports.
Transmit pacing is enabled on a per port basis. When transmit pacing
is enabled, the switch alters its transmission routine during heavy
network activity. When the switch senses heavy traffic, it alters its
transmission routing by intentionally inserting additional delay
between transmission attempts. This added delay reduces collision
rates, thus reducing the number of transmission attempts, which
helps reduce CPU utilization, lightens overall network traffic, and
allows the network time to normalize before attempting
transmission.
1-5
Product Description
If this additional delay is not applied, the switch attempts to transmit
on an overloaded network, increasing the number of unsuccessful
transmission attempts.
For detailed information concerning software and management
features, refer to the
AT- S20 User’s Guide
.
Mirror Port
Media Dependent
Adapters (MDAs)
The switch has a dedicated Mirror port. Administrators can use the
Omega software to configure the Mirror port and modes. The Mirror
port can monitor traffic on any port, one port at a time. A protocol
analyzer or an RMON probe can be connected to the port mirroring
connector using a standard Category 5 UTP cable.
In full-duplex mode the user needs to determine if they want to
monitor TX or only RX data, but in only one direction at a time. In
half-duplex mode, both RX/TX can be monitored simultaneously.
The MDAs come in four versions, the AT-A10 which is the
10/100Base-TX adapter, the AT-A11 which is the 100Base-FX/SC
version, the AT-A20 which is the 100Base-FX/MT version and the
AT-A21 which is the 100Base-FX/VF version. The adapter LEDs, one
for Activity and the other for Link status, are located on the switch’s
front panel under Port Activity.
