MAC tracker

Enter a MAC address, hit Find. ShellYard probes every saved switch in your fleet over SSH or SNMP and reports:

• The switch the MAC is seen on
• The port number
• The VLAN
• Last-seen timestamp
• The IP address the device is using, correlated from ARP

Useful for “which port is this device plugged into?” without walking the rack.

IP correlation from ARP

A MAC hit on its own tells you where a device is plugged in, not what it is. The tracker also reads ARP so a result comes back with the address the device is actually using — which is usually the thing you needed in order to do anything with it.

Supported switch platforms

Cisco IOS and NX-OS, Aruba AOS-CX and AOS-S, Juniper Junos, and Brocade. Platforms outside that set can still be queried by hand through a normal SSH session.

Prefix sweep

Instead of one address, give the tracker an OUI or a MAC prefix and it walks the fleet surfacing every device that matches. Useful for “where did all the Axis cameras end up” or auditing one vendor’s hardware across a site.

Host-key pre-flight

Fan-out across a fleet hits the same unknown-host-key problem as Bulk Command. The tracker scans first and offers a bulk-accept modal, with a per-folder auto-accept toggle for a silent path. Changed keys are still refused — that is the MITM signal, and it is not something a convenience toggle should suppress.
