Disable all interface loop-protect
/interface ethernet set [find ] loop-protect=off
/interface vlan set [find ] loop-protect=off
To change all ports on a MikroTik router using the command line interface (CLI), you can use the following steps:
Step-by-step Guide
1. Connect to your Router
Ensure that you’re connected to your MikroTik device via SSH or Winbox.
2. Open Terminal
Open the terminal in Winbox or directly connect through an SSH client like PuTTY if you’re using CLI mode.
3. List Current Interface Settings
Before making changes, it’s good practice to list current settings:
/interface ethernet print
This will show details of each Ethernet port including its name, speed, duplex, etc.
4. Change All Ports at Once
To change multiple interfaces simultaneously, you can apply bulk commands. For example, let’s say we want to set all ports to 1Gbps full-duplex mode with auto-negotiation disabled:
/interface ethernet set numbers=all speed=1000Mbps full-duplex=yes autonegotiation=no
Explanation:
numbers=all
: Applies changes to all available Ethernet ports.speed=1000Mbps
: Sets the speed to Gigabit (1Gbps).full-duplex=yes
: Enables full-duplex communication.autonegotiation=no
: Disables automatic negotiation for manual configuration.
You can adjust these parameters according to your needs such as setting different speeds (100Mbps
, 10Mbps
), enabling/disabling auto-negotiation, changing MTU size, etc.
5. Verify Changes
After applying the new settings, verify them by listing again:
/interface ethernet print
Check that all ports have been updated correctly.
Additional Tips
- If you need more granular control over specific ports rather than applying global changes, specify individual port names instead of ‘all’. E.g.,
/interface ethernet set ether1 speed=1000Mbps
. - Be cautious when disabling auto-negotiation, especially if the devices connected are not configured similarly. This could lead to link failures or reduced performance.
If any issues arise after configuring, remember that you can always reset configurations manually per-port basis until things stabilize.
