MTU issue on VLAN

Hello,

I need to change VLAN MTU on CCR 1036.

The MTU should be 9000.

I tried both ways: command line and Winbox but it was showing an error.

"failure: could not set mtu"

How can I do it?

Regards,
Shafi

Re: Unexpected Local IPv6 Packet

/ipv6 neighbour print Doesn't really look like broadcast though as the destination is not a broadcast address. Perhaps include the port so you get an idea what the traffic is. Actually IPv6 package is not enabled in my MikroTik. So, pointed command line may not executed. Please note that, I have en...

Re: Random Port Attack

You should inspect your devices. If you watch ether2 (where they are connected to) and see zero tx rate (send) and non-zero rx rate (receive), it's traffic from your devices to internet, not the other way around. You can block it, but it's no solution. You should be more interested in why your devi...

Re: Random Port Attack

What interface is "ether2"? LAN or WAN? Because if it's LAN and that's where your 103.239.5.32/27 subnet is, then first reply was correct. No one is attacking you, it's your devices trying to connect outside. Yes. ether1 is WAN and I have pointed it with a local IP (172.20.104.62) and the...

Re: Want to Block Packets from Outside IPs

/ip firewall filter add chain=input src-address-list=Block_IP action=drop It is normal to see the packets in torch - this is showing the raw data coming in before it is processed by your router. -Chris /ip firewall filter add chain=input src-address-list=Block_IP action=drop is not capturing packet...

Re: Random Port Attack

Are you running my BlackList? It will help protect you from many attacks. If this is a DDoS attack, and you have a dynamic IP, the simple solution is to change your MAC address on the WAN port and reboot the modem to get a new IP address. https://forum.mikrotik.com/viewtopic.php?f=9&t=98804 My ...
