Thank you I tried now but it seems it's more like for package capturing instead showing actual bandwith, or I can't found the proper command flag in help?

No idea what you mean by "via dnf install I can't found any"...what, exactly, are you looking for, and what are you trying to do???

If you're talking about a monitoring solution there are many, including Nagios, Zabbix, and other similar packages. But you don't define what you're trying to do or how often...if this is a one-time thing, you can use something like netstat, tcpdump, or wireshark and capture data for a period and display it in whatever manner you want.

Perhaps iptraf-ng is what you want.

IPTraf-ng is a console-based network monitoring utility. IPTraf gathers data like TCP connection packet and byte counts, interface statistics and activity indicators, TCP/UDP traffic breakdowns, and LAN station packet and byte counts. IPTraf-ng features include an IP traffic monitor which shows TCP flag information, packet and byte counts, ICMP details, OSPF packet types, and oversized IP packet warnings; interface statistics showing IP, TCP, UDP, ICMP, non-IP and other IP packet counts, IP checksum errors, interface activity and packet size counts; a TCP and UDP service monitor showing counts of incoming and outgoing packets for common TCP and UDP application ports, a LAN statistics module that discovers active hosts and displays statistics about their activity; TCP, UDP and other protocol display filters so you can view just the traffic you want; logging; support for Ethernet, FDDI, ISDN, SLIP, PPP, and loopback interfaces; and utilization of the built-in raw socket interface of the Linux kernel, so it can be used on a wide variety of supported network cards.
