Cisco 3700 Series Interface Numbering

Each WAN and LAN interface on a Cisco 3700 series router is identified by a slot number and a unit
number. The Cisco 3700 series includes the Cisco 3725 and Cisco 3745.
Cisco 3725 Router Interface Numbering
The Cisco 3725 router chassis contains the following wide-area network (WAN) and local area network
(LAN) interface types:
