TP-LINK 24-Port 10/100Mbps + 4-Port Gigabit L2 Managed Switch TL-SL5428 Manual De Usuario

Discription：

Designed  for  workgroups  and  departments,  TL-SL5428  from  TP-Link 

provides  wire-speed  performance  and  full  set  of  layer  2  management 

features.  It  delivers  maximum  throughput  where  you  need  it  —  to 

high-performance workgroups at the edge of the network, or as a backbone 

for  Fast  Ethernet  switches  and  high-speed  servers  in  demanding  small 

networks.

IP  Clustering  allows  up  to  32  TL-SG5426  &  TL-SL5428  switches  to  be 

managed by a single IP, regardless of geographical locations. With all units 

identified by a single IP address, the stack could be configured, monitored, 

maintained as a single object.

Traffic running across units in this virtual stack utilizes full-duplex interfaces 

and network wires, eliminating costly and cumbersome cables, minimizing 

the impact of any single point of failure.

To integrate voice, data and video service on one network, TL-SL5428 applies 

rich  QoS  policies  and  voice-based  VLAN.  Administrator  can  designate 

priorities  to  the  traffi-c  based  on  a  variety  of  means  including  IP  or  MAC 

address, TCP or UDP port number, etc, and separate all voice traffic in one 

dedicated VLAN for easy administration and troubleshooting, so voice and 

video are clear, smooth and jitter free.

For  other  multimedia-on-demand  application  such  as  IPTV,  TL-SL5428 

provides  advanced  features  for  easy  stream  management.  For  example, 

IGMP snooping ensures the switch intelligently forward the multicast stream 

only to the appropriate subscribers; IGMP throttling & filtering restrict each 

subscriber on a port level to prevent unauthorized multicast access.

The  TP-Link  fully  managed  L2  switch  TL-SL5428  provides  non-blocking 

switching  solution  for  a  10/100  fast  Ethernet  connection.  It  supports  24 

10/100Mbps  ports  and  4  gigabit  10/100/1000BASE-T  ports. These  gigabit 

copper ports will be disabled if the four 1000BASE-X SFP are used - known as 

dual personality or combo ports. As to the switching capacity, TL-SL5428 has 

a non-blocking aggregated bandwidth of 12.8Gbps.

Access Control Lists (L2/L3/L4) restrict access to sensitive network resources 

by  denying  packets  based  on  source  and  destination  MAC  addresses,  IP 

addresses,  TCP/UDP  ports.  This  is  done  by  hardware,  so  switching 

performance would not be compromised.

Moreover,  Dynamic  ARP  Inspection  which  protects  the  network  from 

"man-in-the-middle"  attacks,  IP  Source  Guard  which  prevents  IP  spoofing 

attacks  such  as  DoS,  together  with  802.1x  port-based  authentication 

provide robust security to the network.

TL-SL5428  caters  to  the  enterprise  management  needs  with  SNMP 

v1/v2c/v3,  RMON,  intuitive  web-based  GUI,  industrial  standard  Command 

Line Interface (CLI), sFlow and advanced features such as 802.1Q tunneling 

(Q-in-Q),  which  enables  service  providers  to  provide  Layer  2 VPN  service, 

often called Layer 2 transparent LAN services (TLS) or Ethernet LAN services, 

by using a VLAN-in-VLAN hierarchy and tagging the tagged packets.

Besides, link aggregation, multiple spanning tree protocol and virtual stack 

will  work  together  to  fulfill  the  enterprise’s  requirements  for  a  highly 

intelligent and scalable network.

Manageability
+ Voice VLAN simplifies telephony installations by keeping voice traffic on a 
separate VLAN for easier administration and troubleshooting
+ IP Clustering provides high scalability and easy Single-IP-Management.
+ Supports Telnet, Cisco Like CLI, SNMP v1/v2c/v3, RMON and web access, 
which are all secured by SSHv2.
+ 802.1ab LLDP automated device discovery protocol facilitates network 
mapping by NMS

Security
+ IP Source Guard prevents IP spoofing attacks such as DoS.
+ Dynamic ARP Inspection blocks ARP broadcasts from unauthorized hosts, 
preventing "man-in-the-middle" attacks.
+ Supports multiple industry standard user authentication methods such as 
802.1x, RADIUS and TACACS+ Authentication
+ L2/L3/L4 Access Control Lists restrict untrusted access to the protected 
resource.

Layer 2 Switching 
+ 802.1Q and 802.1Q tunneling (Q-in-Q) provide point-to-point and multi-
point Ethernet services
+ GVRP (GARP VLAN Registration Protocol) allows automatic learning and 
dynamic assignment of VLANs.

Resiliency and Availability
+ Link aggregation(LACP) increases aggregated bandwidth, optimizing the 
transport of business critical data.
+ IEEE 802.1s Multiple Spanning Tree provides high link availability in mul-
tiple VLAN environments.
+ IGMP snooping automatically prevents flooding of IP multicast traffic.
+ Root Guard protects root bridge from malicious attack or configuration mistakes

Quality of Service
+ Supports L2/L3/L4 granular CoS with 4 priority queues per port.
+ Rate limiting confines the traffic flow accurately according to the preset value.
