You are the on-call network technician for Larkmere Outfitters,
a regional retailer. Customers and staff keep plugging personal streaming sticks and casting dongles
into the open Ethernet jacks of the back-office IDF, where the access switch sw-idf-b2 lives.
Management wants those device families kept off that switch at layer 2.
Your task is to build a MAC-based ACL on sw-idf-b2 that denies the
known hardware-address ranges of those devices, bind it to every access port, and persist the change so it
survives a reboot.
Create a named ACL, then add deny entries. In this console a mask byte of
FF means ignore that byte (match any value); a mask byte of
00 means match that byte exactly.
| # | Action | Dest | Source value | Source mask | |
|---|---|---|---|---|---|
| No entries yet. | |||||
Bind an ACL to a single port, or use Copy Settings to apply one port's binding to many ports at once.

Changes you make are in the running configuration. Save them to the startup configuration so they persist across a reboot or power cycle.
