Update Mikrotik Routeros Versi 6.41 Stable (Master-Port Hilang?)

Halo teman - teman pengguna Mikrotik RouterOS. Kali ini ada kabar lagi perihal update Mikrotik RouterOS Versi 6.41 Stable. Versi ini yaitu versi yang stabil. Update tersebut dirilis pada tanggal 22 Desember 2017. Bagi teman - teman yang memakai Mikrotik RouterOS dapat melaksanakan update ke Mikrotik RouterOS versi 6.41.

Pada Mikrotik RouterOS versi 6.41 kalau ingin mengupdate, harus dilakukan backup terlebih dahulu. Sebenarnya kalau ingin melaksanakan upgrade ataupun update baiknya harus di backup terlebih dahulu. Hal tersebut untuk mengantisipasi kalau ada kegagalan dalam update tersebut. Kalau sudah dibackup, maka kalau ada persoalan dapat eksklusif di restore. Nampaknya dalah update kali ini perlu lebih hati - hati sebab ada banyak hal gres di Mikrotik RouterOS versi 6.41.

Ada implementasi bridge yang gres di Mikrotik RouterOS versi 6.41 yang mana telah mendukung hadware offload (hw-offload). Pada update Mikrotik RouterOS versi 6.41 akan merubah semua interface pada konfigurasi master port menjadi bridge. Maka opsi master-port akan hilang. Jika teman - teman melaksanakan downgrade, maka konfigurasi master-port tersebut tetap akan hilang dan tidak otomatis restore. Makara perlu dilakukan backup sebelum update ke Mikrotik RouterOS versi 6.41.

Ada banyak pembaharuan pada Bridge di Mikrotik RouterOS versi 6.41. Pembaharuan tersebut menambah beberapa proteksi fitur yang cukup penting.  Pada bridge tersebut ada proteksi vlan, perbaikan pada fast-forward, perbaikan setting arp, implementasi MSTP, dan lain masih banyak lagi. Untuk konfigurasi master-port di Mikrotik RouterOS versi 6.41 tidak ada dan dipindah ke bridge.

Pembaharuan juga ada pada wireless. Ada proteksi driver gres yang mendukung 80+80 MHz. ada perbaikan juga pada btest, bgp, arp, dan lain masih banyak lagi. Berikud dibawah ini yaitu changelog Mikrotik RouterOS versi 6.41.

What's new in 6.41 (2017-Dec-22 11:55):
Important note!!! Backup before upgrade!
RouterOS (v6.40rc36-rc40 and) v6.41rc1+ contains new bridge implementation that supports hardware offloading (hw-offload).
This update will convert all interface "master-port" configuration into new bridge configuration, and eliminate "master-port" option as such.
Bridge will handle all Layer2 forwarding and the use of switch-chip (hw-offload) will be automatically turned on based on appropriate conditions.
The rest of RouterOS Switch specific configuration remains untouched in usual menus for now.
Please, note that downgrading to previous RouterOS versions will not restore "master-port" configuration, so use backups to restore configuration on downgrade.
