Cisco MWR 1941-DC-A Router Interface Numbering
Cisco MWR 1941-DC-A Router Interface Numbering
Each network interface on a Cisco MWR 1941-DC-A router is identified by a slot number and a port
number.
Figure 1-6
shows an example of the interface numbering on a Cisco MWR 1941-DC-A router.
Slot and Port Numbering
The Cisco MWR 1941-DC-A router chassis contains the following LAN and WAN interface types:
•
Two built-in Fast Ethernet LAN interfaces (labeled FE0 and FE1)
•
Three slots for installing 2-port T1/E1-RANs (labeled W0, W1, and W2)
•
One slot for installing a network module
The logical slot numbers are as follows:
•
0 for all built-in interfaces
•
0 for all built-in 2-port T1/E1-RAN slots
•
1 for the network module slot
