Understanding Interface Numbering Chapter 1 Understanding Interface Numbering and Cisco IOS Software Basics - If physical slot W0 is empty and physical slot W1 contains a 1-port serial WIC, the interface number in the WIC is numbered Serial 0/0. - If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1 is numbered Serial 0/2. - If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1 is numbered BRI 0/0. Voice Interface Numbering in Cisco 2600 Series Routers Voice interfaces are numbered differently from the WAN interfaces described in the previous section. Voice interfaces are numbered as follows: chassis slot/voice module slot/voice interface If a 4-channel voice network module is installed in chassis slot 1, the voice interfaces are: • 1/0/0-Chassis slot 1/Voice module slot 0/Voice interface 0 • 1/0/1-Chassis slot 1/Voice module slot 0/Voice interface 1 • 1/1/0-Chassis slot 1/Voice module slot 1/Voice interface 0 • 1/1/1-Chassis slot 1/Voice module slot 1/Voice interface 1 Cisco 3600 Series Interface Numbering Each individual network interface on a Cisco 3600 series router is identified by a slot number and a unit number. Cisco 3600 Series Router Slot Numbering A Cisco 3600 series router chassis includes up to six slots in which you can install modules. The Cisco 3600 series includes the Cisco 3660 (see Figure 1-3), Cisco 3640 (see Figure 1-4) and Cisco 3620 routers (see Figure 1-5). The Cisco 3660 has six network module slots, the Cisco 3640 has four slots, the Cisco 3620 has two slots, and the Cisco 3631 (see Figure 1-6) has four slots. You can install any module into any available slot in the chassis. Software Configuration Guide For Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers 1-4 OL-1957-04

Understanding Interface Numbering
–
If physical slot W0 is empty and physical slot W1 contains a 1-port serial WIC, the interface
number in the WIC is numbered Serial 0/0.
–
If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the interfaces
in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1
is numbered Serial 0/2.
–
If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the interfaces
in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1
is numbered BRI 0/0.
Voice Interface Numbering in Cisco 2600 Series Routers
Voice interfaces are numbered differently from the WAN interfaces described in the previous section.
Voice interfaces are numbered as follows:
chassis slot/voice module slot/voice interface
If a 4-channel voice network module is installed in chassis slot 1, the voice interfaces are:
•
1/0/0—Chassis slot 1/Voice module slot 0/Voice interface 0
•
1/0/1—Chassis slot 1/Voice module slot 0/Voice interface 1
•
1/1/0—Chassis slot 1/Voice module slot 1/Voice interface 0
•
1/1/1—Chassis slot 1/Voice module slot 1/Voice interface 1
Cisco 3600 Series Interface Numbering
Each individual network interface on a Cisco 3600 series router is identified by a slot number and a unit
number.
Cisco 3600 Series Router Slot Numbering
A Cisco 3600 series router chassis includes up to six slots in which you can install modules. The
Cisco 3600 series includes the Cisco 3660 (see
Figure 1-3
), Cisco 3640 (see
Figure 1-4
) and Cisco 3620
routers (see
Figure 1-5
). The Cisco 3660 has six network module slots, the Cisco 3640 has four slots,
the Cisco 3620 has two slots, and the Cisco 3631 (see
Figure 1-6
) has four slots. You can install any
module into any available slot in the chassis.
