When set to on, the port will generate pause frames to the upstream device to temporarily stop the packet transmission. Tx-flow-control ( on | off | auto Default: off) Default value is 'yes' because older NICs do not support it. If this value is set to 'no', the router automatically detects whether the NIC is connected with a device in the network or not. When copper mode is selected, the interface will only work through RJ45 Ethernet port.ĭisable-running-check ( yes | no Default: yes)ĭisable running check. When sfp mode is selected, the interface will only work through SFP/SFP+ cage. after reboot), the priority will be the SFP/SFP+ port. If both ports are connected at the same time (e.g. In case this link fails, the other port will try to establish a new link. When auto mode is selected, the port that was first connected will establish the link. RX limit is supported only on Atheros8327/QCA8337 switch-chip ports.Ĭable-setting ( default | short | standard Default: default)Ĭhanges the cable length setting (only applicable to NS DP83815/6 cards)Ĭombo-mode ( auto | copper | sfp Default: auto) TX limit is supported on all Atheros switch-chip ports. Sets max rx/tx bandwidth in kbps that will be handled by an interface. Note2: Gigabit Ethernet and NBASE-T Ethernet links cannot work with auto-negotiation disabled.īandwidth ( integer/integer Default: unlimited/unlimited).Note1: Auto-negotiation should not be disabled on one end only, otherwise Ethernet Interfaces may not work properly.When enabled, the interface "advertises" its maximum capabilities to achieve the best connection possible. Therefore for communications to be successful, a valid static entry must already exist.Īuto-negotiation ( yes | no Default: yes) No dynamic entries will be automatically stored in the ARP table. reply-only - the interface will only reply to requests originated from matching IP address/MAC address combinations which are entered as static entries in the ARP table.proxy-arp - the router performs proxy ARP on the interface and sends replies to other interfaces.local-proxy-arp - the router performs proxy ARP on the interface and sends replies to the same interface.disabled - the interface will not use ARP.Advertising higher speeds than the actual interface supported speed will have no effect, multiple options are allowed.Īrp ( disabled | enabled | local-proxy-arp | proxy-arp | reply-only Default: enabled) Through RouterOS, it is possible to control different Ethernet related properties like link speed, auto-negotiation, duplex mode, etc, monitor a transceiver diagnostic information and see a wide range of Ethernet related statistics.Īdvertise ( 10M-full | 10M-half | 100M-full | 100M-half | 1000M-full | 1000M-half | 2500M-full | 5000M-full | 10000M-full Default: )Īdvertised speed and duplex modes for Ethernet interfaces over twisted pair, only applies when auto-negotiation is enabled. 1Gbps Ethernet over twisted pair and SFP interface) allowing to select the most suitable option or creating a physical link failover. Certain RouterBoard devices are equipped with a combo interface that simultaneously contains two interface types (e.g. MikroTik RouterOS supports various types of Ethernet interfaces - ranging from 10Mbps to 10Gbps Ethernet over copper twisted pair, 1Gbps and 10Gbps SFP/SFP+ interfaces and 40Gbps QSFP interface.
