24-Port Managed Fast Ethemet Switch with2GBIC Gigabit Dual Media Ports

Model : AAMS226

AAMS226 is a Managed Fast Ethernet switch that supports SNMP,
Web UI and CLI management interface and with 24 10/100Base-TX
(RJ-45 connectors) and 2 Gigabit dual media (RJ-45/GBIC) ports.
It is a standard switch that meets all IEEE 802.3/u/x/z Gigabit,Fast Ethernet specifications.
In addition, the switch implements the QoS (Quality of Service), VLAN, Mac Filtering Policy, Port Mirror, VLAN and full L2 protocols.
It has a rich feature set suitable for multimedia applications.
In this switch, Port 25,26 supports two types of media TP and GBIC Fiber
(LC,BiDi-SC); both ports support 10/100/1000Mbps TP
or 1000Mbps GBIC Fiber with auto-detected function.
1000Mbps GBIC Fiber transceiver is used for high-speed connection expansion.

QoS with four priority queues
The QoS feature provides four internal queues to support four different classifications of traffic
High priority packet streams experience less delay inside the switch,
The AMS226 can classify the packet as one of the four priorities according to 802.
1p priority tag, DiffServ and/or I TOS, The QoS operate at full wire speed.
The actual scheduling at each egress port can be based upon a strict priority, weighted round robin or a mix of both

Port Mirroring
This mechanism helps track network errors or abnormal packet transmission without interrupting the flow of data.
Allow ingress traffic to be monitored by a single port that is defined as mirror capture port. The mirror capture port can be any 10/100 port, 10/100/1000 port.
Mirroring multiple ports is possible but can create congestion at the mirror capture port.

Q-in-Q VLAN for performance & security
The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance.
Q-in-Q, the use of double VLAN tags is an efficient method for enabling Subscriber
Aggregation. This is very useful in the MAN.

Isolated Group provides protection for certain ports
The isolated group feature allows certain ports to be designated as protected.
All other ports are non-isolated. Traffic between isolated group members are blocked. Traffic can only be sent from isolated group to non-isolated group.

Mac-based 802.ad LACP with automatic link fail-over
Dynamic fail-over means packets will not get assigned to any trunk member port that has failed.
If one of the ports were to fail, traffic will automatically get distributed
to the remaining active ports.

802.1x Access Control improves network security
802.1x features enable user authentication for each network access attempt. Port security features allow you to limit the number of MAC addresses per port in order to control the
number of stations for each port. Static MAC addresses can be defined for each port to ensure only registered machines are allowed to access. By enabling both of these features, you can establish an access mechanism based on user and machine identities, as well as control the number of access stations.

802.1d Compatible & 802.1w Rapid Spanning Tree
For mission critical environments with multiple switches supporting STP, you can configure the switches with a redundant backup bridge path, so transmission and reception of packets can
be guaranteed in event of any failover switch in the network.

2 Dual Media ports for flexible fiber connection
Ports 25,26 dual media ports are provided for flexible fiber connection. You can select to install optional transceiver modules in these slots for short, medium or long distance fiber backbone attachment. Use of the GBIC will disable their corresponding
built-in 10/100/1000Base-T connections.

Broadcast/Multicast/unknown-unicast Storm Control
To Limit too many broadcast/multicast/unknown-unicast flooding in the network, broadcast/multicast storm control is used to restrict excess traffic. Threshold values are
available to control the rate limit for each port. Packets are discarded if the count exceeds the configured upper threshold.
