[SOHO交换机研究]

2015年6月6日 星期六
想买一个小交换机SOHO.
研究网络,公司太烂申请太麻烦,IT也不一定配合.
一般买1000M交换机的个人都是买NAS,网路存储盘,提高网络速度,进一步来说提供聚合网络,2个网卡合并一个IP,提供服务.
目的:
研究网卡绑定技术.
研究MTU 巨幅帧 
VLAN 路由.
VPN ? 
key point : 
0.1000M 网络.
1.8口交换机
2.支持vlan
3.支持Qos
4.支持端口聚合.
5.POE 通过网线供电给USB CAM 功能.
taobao美国旧货.
新货.
最后的选择范围: 
Cisco SG200-08   taobao 全新 580 
Netgear Prosafe Gs108Tv2 2手480  800~1000
端口聚合协议
 Link Aggregation Control Protocol (LACP) (802.3ad) 
行业标准的链路聚合,符合IEEE 802.3ad标准(仅静态支持,不支持LACP)
支持4个链路聚合组,每组多达4个端口
Cisco SG200-08 8-port Gigabit Smart Switch (SLM2008T-NA)
http://www.amazon.com/Cisco-SG200-08-8-port-Gigabit-SLM2008T-NA/dp/B004OA721C/ref=sr_1_3?s=pc&ie=UTF8&qid=1433523097&sr=1-3&keywords=LACP
Background: I was needing 802.3ad/LACP to aggregate ethernet ports from my main server and alleviate that bottleneck. After trying different load balancing options (TLB/ALB) on my old Dlink, I decided it wasn't worth the headache and started looking for something that properly did Link Aggregation.
I was looking at a similar Trendnet when I found this one from Cisco, looked at the reviews of both, and got the SG200-26. Had a couple of issues with LACP initially, but flashed the firmware to the latest and everything just works like a charm now. I'm very happy with it, and my main server has a 4Gb link now. I then bought a SG200-8 for an area that didn't get enough network drops, and setup a 2Gb link to it and fixed that bandwidth issue as well. I haven't gotten around to any QoS and VLAN settings yet, as that wasn't what I needed the switch for, but I'll probably use that in the future.
与 SG200-08P 区别  
POE Power Over Ethernet)指的是在现有的以太网Cat.5布线基础架构不作任何改动的情况下,在为一些基于IP的终端(如IP电话机、无线局域网接入点AP、网络摄像机等)传输数据信号的同时,还能为此类设备提供直流供电的技术。 POE也被称为基于局域网的供电系统(POL, Power over LAN )或有源以太网( Active Ethernet),有时也被简称为以太网供电,这是利用现存标准以太网传输电缆的同时传送数据和电功率的最新标准规范,并保持了与现存以太网系统和用户的兼容性。

Netgear Prosafe Gs108Tv2 8-Port Gigabit Smart Switch - Switch - Managed - 8 X 10/100/1000 - Desktop
PROSAFE 8PT GBIT SMART SWCH With 8 10/100/1000 Mbps ports, each capable of powering 2000 Mbps of data throughput in full-duplex mode per port, the GS108T is an ideal solution for extending network connections into conference room, labs, lobbies and department workgroups. It enables SMB networks to support Voice over IP (VoIP), streaming media, multicasting, security, and many other bandwidth-intensive applications like ERP and large file transfers. The GS108T comes with a comprehensive set of features, such as access control lists (ACL), 802.1x port authentication, enhanced QoS, rate limiting and IGMP snooping among others to provide a small or medium-sized business with a network that is geared for growth while ensuring performance and reliability. In addition, the GS108T supports IEEE 802.3af standard for Power over Ethernet (PoE). It can obtain its power from either a PoE source or from an external AC power adapter. This gives an SMB flexibility when installing the switch in places where a power outlet is not present. The GS108T comes with an intuitive, Web-browser interface which offer simple Smart Switch management, making it a snap to monitor switch performance, configure ports, even set up port trunks, VLANs, and traffic prioritization. Alternatively, you can use SNMP-based software to manage your Smart Switch. NETGEAR ProSafe Smart Switches are ideal for adding basic management to your unmanaged networks or extending your managed networks.
