Wiring Closet Configuration

In a wiring closet configuration, routing might not be enabled on the switch. In this configuration, the
switch can still support a VLAN map and a QoS classification ACL. In
and Host Y are in different VLANs and are connected to wiring closet switches A and C. Traffic from
Host X to Host Y is eventually being routed by Switch B, a Layer 3 switch with routing enabled. Traffic
from Host X to Host Y can be access-controlled at the traffic entry point, Switch A.

of VLAN IDs (12, 22, 30). Spaces around the comma and hyphen are
optional.
Display the access list configuration.
(Optional) Save your entries in the configuration file.
