PortFinder

A wall jack, a cable that disappears into the wall… and no idea which port it comes out on. PortFinder polls your switches and answers within seconds: “Floor 2, port 14”. WHERE AM I PLUGGED IN? Plug your Mac (or your iPad with an Ethernet adapter) into the jack and tap the button: PortFinder finds your address in the tables of every switch and shows the switch and port in large type. SEARCH An IP address, a MAC address or simply “Floor 2 port 14”: PortFinder cross-references ARP and forwarding tables, rules out inter-switch links and points to the probable location. LINK MONITORING You are in the wiring closet while a colleague plugs a cable in at the other end of the building? The port that just went “Up” appears immediately, along with the detected device. PORT DETAILS Link state, speed, duplex, VLAN, STP, LLDP neighbor, PoE power and the list of connected devices with their addresses. MULTI-VENDOR PortFinder reads the standard MIBs over SNMP v2c (IF-MIB, Q-BRIDGE-MIB, IP-MIB, POWER-ETHERNET-MIB, LLDP-MIB): Cisco, Aruba / HPE, Juniper, Extreme, Brocade / Ruckus, Dell, Netgear, Ubiquiti, MikroTik… A read-only community is all it needs, no “enable” password. Brocade / Ruckus ICX switches can also be polled over Telnet (FastIron CLI). MAC AND IPAD, IN SYNC Buy once, use on Mac and iPad. Your switches, their passwords and SNMP communities follow you on both devices through end-to-end encrypted sync: everything is encrypted on the device with a passphrase only you know. The server cannot read any of it. Sync is optional: without an account, PortFinder works entirely offline. DEMO MODE No switch at hand? Three simulated switches answer inside the app, so you can try every feature before connecting the real ones. Built by a network technician for network technicians: nothing to install on the switches, nothing to write, read-only.
