看了中國那邊拆 UDM 的文,下面回文說 UDM 會有過熱的問題,不曉得實際用這台的人有無相同感覺?


之前較少聽到有過熱的問題, 平均溫度在 60度C 似乎蠻常見的.

把 UniFi USP-Plug 玩掛了

上週將 beta firmware 上傳至 UniFi Smart Power Plug, 結果 Controller 一直顯示更新中, 就這樣擺了一天, 始終無法完成更新, 索性 plug 拔掉重新插電, 結果 Controller 中就再也看不到它了, us$19 算是沒了.

這是 wifi device, 心想更新 firmware 掛了, 可能也要送回工廠才能修吧, 今天隨手 google 了一下 "unifi usp-plug recovery", 結果真的有最後一招急救法.

照著做真的救回來了.

IGMP snooping enable/disable

今天試著用 VLC 測試了一下 LAN 內的 multicast 功能, UniFi Network 預設是 IGMP snooping 這功能 disable, 這樣如果區網內有 multicast 封包時, 所有的 switch port 都會收到 broadcast 封包.

利用 VLC 做為 multicast sender, 在任一 switch port 上面用 wireshark sniffer captuer 封包, 確實都有 broadcast packets, 於 UniFi Controller 啟用 IGMP snooping 後就無此現象了.

想請問一下

如果只有一條網路線跟孔

想要在天花板上同時安裝 AP AC LR跟G3 Web Cam 兩個設備

在天花板處利用1轉2 RJ45分接器,然後讓這條透過POE Adapter 同時供電這2個設備嗎?

因為天花板上沒有電源插頭,又懶得拉線上去....

另外之前看到UNIFI打算停止Web Cam的功能,現在買會不會之後不能用呢?

USW-Flex Switch 可以用 PoE 供電, 然後再分接給 AC-LR & UVC-G3, 你可以查一下

至於 UniFi 是停掉 UniFi Video software 版本, 以後會主推 UniFi Protect & UNVR.

最近買了unifi產品, 但利用NAS安裝控制器後,在裝置那邊都看不到產品,完全空的
變成switch無法接管,因為偵測不到,但用APP卻有出現switch ,
目前只能用手機APP設定.
*UniFi控制器版本為: 5.14.22




使用裝置如下:
Mikrotik路由器
USW-Lite-8-PoE
U6-Lite


不知道有沒有人遇過此情況,還是說要搭配Unifi路由器才能呢?
