ZyXEL 8埠GS-108S v2開箱

8埠的Switch有什好看的?

的確沒什好提的...不過支援layer3驗證的Switch不多,大多是layer2吧.
不過layer3驗證可用在MOD或VoIP視訊電話,將資料傳到正確的Port,這點就與眾不同.

尤其layer3與layer2的Switch價格相同的情況下,您又會做何選擇?

聽了Edkang大的建議,於是抱了"ZyXEL 8埠 GS-108S v2"回家.




過程店員一直在旁邊洗腦要我改買Buffalo的8埠Switch是怎麼回事?
不過我知道我的需求...layer2的Switch閃邊去吧

ZyXEL GS-108S還有個兄弟是5埠的GS-105S ,差價在$300之間.
不過兩兄弟都不到$1000元的情況下,我選擇了GS-108S

嗯...別開...
阿...來不及了...
GS-108S v2 未上市前資料有寫支援IGMP協定...但實際上市後資料卻消掉支援IGMP協定這句...
被合勤給表了一次...

似乎台灣常見8-PORT GBE無網管型的SWITSH晶片都還沒有支援IGMP...
有支援的都是5-PORT

NETGEAR 8 Port Gigabit Smart Switch (GS108T,GS108Tv2)就有..但台灣瀚錸好像沒代理..

合勤當初的資料



合勤現在的資料

是這樣嗎? 以為買到好東西~

不過沒差啦,自己的ASUS分享器也支援IGMP-Proxy /IGMP-Snooping
看規格 似乎是螃蟹晶片
網路設備 小弟還是偏好 intel 或boardcom
前幾天才買 1299
netgear 8port giga 交換器

GS-108S v2

應該是使用Realtek晶片 RTL8370/RTL8370M
嗯...Realtek 資料上有寫
RTL8370(M) supports IPv4 IGMPv1/v2/v3 and IPv6 MLDv1/v2 snooping.

所以要看ZyXEL有沒有開啟支援...


Layer 2 Managed 10/100/1000 Switch Controllers

General Description
The RTL8370 is an LQFP128 E-PAD, high-performance 8-port Gigabit Ethernet switch, and the RTL8370M is a TQFP176 E-PAD, high-performance 8+2-port Gigabit Ethernet switch.
Both the RTL8370 and RTL8370M feature low-power integrated 8-port Giga-PHYs that support 1000Base-T, 100Base-T, and 10Base-T.

The RTL8370M supports two extra GMII/RGMII/MII ports for specific applications. The RTL8370 and RTL8370M integrate all the functions of a high-speed switch system; including SRAM for packet buffering, non-blocking switch fabric, and internal register management into a single CMOS device. Only a 25MHz crystal is required; an optional EEPROM is offered for internal register configuration.

The embedded packet storage SRAM in the RTL8370(M) features superior memory management technology to efficiently utilize memory space. The RTL8370(M) integrates an 8K-entry look-up table with a 4-way XOR Hashing algorithm for address searching and learning. The table provides read/write access from the EEPROM Serial Management Interface (SMI), and each of the entries can be configured as a static entry. The entry aging time is between 200 and 400 seconds. Eight Filtering Databases are used to provide Independent VLAN Learning and Shared VLAN Learning (IVL/SVL) functions.

Unfinished file and contains much errors. Do not use for anything. The Extension GMAC0 and Extension GMAC1 of the RTL8370M implement dual GMII/RGMII/MII interfaces for connecting with an external PHY or MAC in specific applications. This interface could be connected to an external CPU or RISC as 8-port Gigabit Router applications. In router applications, the RTL8370(M) supports Port VID (PVID) for each port to insert a PVID in the VLAN tag on egress. When using this function, VID information carried in the VLAN tag will be changed to PVID.
Note: The RTL8370M (only) Extra Interface (Extension GMAC0 and Extension GMAC1) supports:

Gigabit Media Independent Interface (GMII)
Reduced Gigabit Media Independent Interface (RGMII)
Media Independent Interface (MII)
The RTL8370(M) supports standard 802.3x flow control frames for full duplex, and optional backpressure for half duplex. It determines when to invoke the flow control mechanism by checking the availability of system resources, including the packet buffers and transmitting queues. The RTL8370(M) supports broadcast/multicast output dropping, and will forward broadcast/multicast packets to non-blocked ports only. For IP multicast applications, the RTL8370(M) supports IPv4 IGMPv1/v2/v3 and IPv6 MLDv1/v2 snooping.

In order to support flexible traffic classification, the RTL8370(M) supports 64-entry ACL rule check and multiple actions options. Each port can optionally enable or disable the ACL rule check function. The ACL rule key can be based on packet physical port, Layer2, Layer3, and Layer4 information. When an ACL rule matches, the action taken is configurable to Drop/Permit/Redirect/Mirror, change priority value in 802.1q/Q tag, and rate policing. The rate policing mechanism supports from 8Kbps to 1Gbps (in 8Kbps steps).

In Bridge operation the RTL8370(M) supports 16 sets of port configurations: disable, block, learning, and forwarding for Spanning Tree Protocol and Multiple Spanning Tree Protocol. To meet security and management application requirements, the RTL8370(M) supports IEEE 802.1x Port-based/MAC-based Access Control. For those ports that do not pass IEEE 802.1x authentication, the RTL8370(M) provides a Port-based/MAC-based Guest VLAN function for them to access limited network resources. A 1-set Port Mirroring function is configured to mirror traffic (RX, TX, or both) appearing on one of the switch’s ports. Support is provided on each port for multiple RFC MIB Counters, for easy debug and diagnostics.

To improve real-time or multimedia networking applications, the RTL8370(M) supports eight priority assignments for each received packet. These are based on (1) Port-based priority; (2) 802.1p/Q VLAN tag priority; (3) DSCP field in IPv4/IPv6 header; and (4) ACL-assigned priority. Each output port supports a weighted ratio of eight priority queues to fit bandwidth requirements in different applications. The input bandwidth control function helps limit per-port traffic utilization. There is one leaky bucket for average packet rate control for each queue of all ports. Queue scheduling algorithm can use Strict Priority (SP) or Weighted Fair Queue (WFQ) or mixed.

The RTL8370(M) provides a 4K-entry VLAN table for 802.1Q port-based, tag-based, and protocol-based VLAN operation to separate logical connectivity from physical connectivity. The RTL8370(M) supports four Protocol-based VLAN configurations that can optionally select EtherType, LLC, and RFC1042 as the search key. Each port may be set to any topology via EEPROM upon reset, or EEPROM SMI Slave after reset.

In router applications, the router may want to know the input port of the incoming packet. The RTL8370(M) supports an option to insert a VLAN tag with VID=Port VID (PVID) on each egress port. The RTL8370(M) also provides an option to admit VLAN tagged packet with a specific PVID only. If this function is enabled, the RTL8370(M) will drop all non-tagged packets and packets with an incorrect PVID.

請教一下有沒有支援IGMP 在使用上的差異是?

MOD與電腦同接在小烏龜,
當MOD播映影片不會讓電腦上網受影響是因為小烏龜內建IGMP-Snooping的功能.

IGMP-Snooping可以讓mod封包只往mod送,而不會往電腦跑.

如果小烏龜沒預先開啟IGMP-Snooping ,
那mod要接在分享器或Switch上就只依靠這些機器支援IGMP,
不然電腦與MOD同接在LAN埠時就會發生封包亂竄的衝突...

導致MOD播放出現馬賽克,電腦網路發生降速的情形.

這...用白話一點的說明好了...

multicast多重傳播數據流範圍為224.0.0.0到239.255.255.255
這是做為減少網路資源消耗,所做的群播協定...如圖本來同一訊號分三次傳變成一次訊號傳..
但是他屬於L2廣播派送...在一般的SWITCH並不會去判別...
收到一個multicast和broadcast封包時做的事是一樣的..
把這個封包拷貝成很多份丟到每一個switch port上...
然後就會傳到沒在使用群播的機器上,造成壅塞...



為了改善產生壅塞問題...所以就搞了一個IGMP協定...
讓路由器能知道如果下層終端機不需要接收multicast,就會丟棄該封包...
就更能節省網路頻寬...



目前應該遇得到的是IGMP V2的應用...
IGMP Snooping
是SWITCH自行建立一張對照表,作用於這一個SWITCH所使用PORT
如果內部網路有IP camera 或NAS做多媒體主機...這功能要優先考慮...
以gfx大大的華碩AC66u就是LAN1-4 port

IGMP proxy
是作用於一個專用PORT,像特殊的多媒體用SWITCH會有一個PORT專門接多媒體主機..
ROUTER的話通常會做在對外的埠...
以gfx大大的華碩AC66u應該就是WAN port
