Paradyne 317x E1 manual Interface Group ± ªifIndexº Object ifEntry

Interface Group ± ªifIndexº Object (ifEntry 1)

This object provides the index into the ifTable and typically into tables in other MIBs also. The values of the ifIndex object do not vary between models even though not all indexes are supported for a particular model. When an unsupported index is accessed, ªnoSuchNameº is returned.

The following are the values of the ifIndexes for all

E1 DSU/CSU models:

•1 ± Net E1

•2 ± DTE E1

•3 ± COM port

•4 ± (not used)

•5 ± Auxiliary RS-232 port

•6 ± DCE port 1

•7 ± DCE port 2

•8 ± DCE port 3

•9 ± DCE port 4

The supported ifIndexes for the 3172 DSU/CSU are:

•Net E1

•DTE E1

•COM port

•Auxiliary RS-232 port

•DCE port 1

•DCE port 2

The supported ifIndexes for the 3174 DSU/CSU are:

•Net E1

•DTE E1

•COM port

•Auxiliary RS-232 port

•DCE port 1

•DCE port 2

•DCE port 3

•DCE port 4

Interface Group ± ªifDescrº Object (ifEntry 2)

This object provides the textual information about the interface. Each interface displays a text string as shown below:

Network E1:	ªNetwork E1. E1 DSU/CSU,
	Hardware Version: [CCA number
	for the CSU board]º.
DTE E1:	ªDTE E1. E1 DSU/CSU,
	Hardware Version: [CCA number
	for the CSU board]º.
COM:	ªCOM port. E1 DSU/CSU,
	Hardware Version: [CCA number
	for the CSU board]º.
AUX:	ªAUX port. E1 DSU/CSU,
	Hardware Version: [CCA number
	for the CSU board]º.
Data Ports:	ªData Port n. E1 DSU/CSU,
	Hardware Version: [CCA number
	for the DSU board]º (where n is 1
	to 4).

Interface Group ± ªifTypeº Object (ifEntry 3)

This object identifies the type of the interface based on the physical/link protocol(s) immediately below the network layer. Only the following values are supported by the E1 DSU/CSU:

•e1(19) ± Used for the network and DTE Drop/Insert interfaces.

•propPointToPointSerial(22) ± Used for the synchronous data ports and for the COM port when the port is not configured as the SNMP management interface.

•ppp(23) ± Used for the AUX or COM port when the port is configured for PPP.

•slip(28) ± Used for the COM port when the port is configured for SLIP.
