T1/E1 WAN Configuration Guide Physical Interface Configurations (T1, E1, and Ethernet)

Physical Interface Configurations (T1, E1, and Ethernet)

To begin configuring physical interfaces, you must first activate the appropriate interface configuration

mode from the Global configuration prompt. For example, enter the following commands to activate the

interface configuration mode for the first T1 interface on a T1 module inserted in slot 1:

>enable

#config terminal

(config)#interface t1 1/1

(config-t1 1/1)#

All interfaces are disabled by default and must be activated using the no shutdown command. Interfaces

will not be able to pass data until this command is entered.

Configuring Ethernet Interfaces

Ethernet interface configuration can range from assigning an IP address and activating the interface to

activating the DHCP client to poll the network DHCP server to gain an IP address. Standard Ethernet

configurations generally contain an IP address, a speed, and a duplex setting. By default, all NetVanta

Ethernet interfaces are configured to auto-detect the speed (as 10 or 100 Mbps) and are set to full-duplex.

For most cases, these settings should suffice and will not be changed from the default state.

The following example commands configure an IP address of (10.10.0.7/24) and activates the interface for

the eth 0/1 interface:

>enable

#config terminal

(config)#interface eth 0/1

(config-eth 0/1)#ip address 10.10.0.7 255.255.255.0

(config-eth 0/1)#no shutdown

(config-eth 0/1)#exit

(config)#

Configuring T1 Interfaces

There are four main settings to consider when configuring T1 network interfaces. The line coding

(coding), framing format (framing), active channels (tdm-group), and clock source (clock source) must

all be configured to match the circuit supplied by your network provider. By default, all NetVanta T1

interfaces are configured for ESF (framing esf) and B8ZS (coding b8zs), and to recover clocking from the

network circuit (clock source line). Generally, the line coding, framing format, and clock source default

values will be the correct ones for your application and should not be changed.

Each configured T1 interface must have the active channels specified using the tdm-group command

because there are no default TDM groups defined. The active channels are entered as a single number

representing 1 of the 24 T1 channel timeslots or as a contiguous group of channels.

The NetVanta Network Interface Modules (NIMs) use a slot/port notation for interface

identification (e.g., t1 1/1). All non-modular interfaces built into the base unit are

identified using 0 as the slot number (e.g. eth 0/1).
