Cisco and Windows Commands in Linux

You know the command on IOS or Windows. This is the one that does the same thing on Linux — with example output, the conceptual difference explained, and a lab to try it in.

Cisco IOS

show ip route ip route show show ip interface brief ip -brief addr show show arp ip neigh show show ip ospf neighbor birdc show ospf neighbors show running-config ip addr show; ip route show; iptables-save show mac address-table bridge fdb show show ip bgp summary birdc show protocols show access-lists iptables -L FORWARD -n -v --line-numbers show ip nat translations conntrack -L

Legacy Linux (net-tools)

ifconfig ip addr show netstat ss route -n ip route show

Windows / legacy Unix

nslookup dig

Windows

tracert traceroute ipconfig ip addr show

Run any of them for real

Every translation links to a lab you can run live on real Linux networking in your browser — namespaces, BIRD2, iptables. Not a vendor emulator, and nothing to install.
