Viewing Operational Information

number, and the operational status of each interface (up or down). This information can help to determine system problems by identifying those physical interfaces that are not operating as expected. Refer to the following example:

[System Name]> NEIF
id Name		Type	Slot	Port	Status
-- ----		----	----	----	------
1	Ethernet Port 1	Ethernet	3	1	up
2	Ethernet Port 2	Ethernet	3	2	down
3	BRI.LINE.1	BRI D-Channel	1	1	up
4	BRI.LINE.1	BRI D-Channel	1	2	up
5	V.35.LINE	V.35	2	1	down

The definitions of the interface types and the associated status possibilities are as follows:

Ethernet

Each Ethernet port is considered an Ethernet interface. An Ethernet interface is “up” if the Ethernet port is capable of forwarding packets to/from the LAN. An Ethernet interface is “down” if the Ethernet port cannot be used to forward packets to/from the LAN.

Basic Rate (D-Channel)

Each Basic Rate line which contains at least one data link is considered a Basic Rate (D-Channel) interface. A Basic Rate (D-Channel) interface is “up” if at least one data link associated with the interface is “up.” A Basic Rate interface is “down” if none of the data links associated with the interface is “up.”

Basic Rate (Permanent)

Each Basic Rate line which is used by a dedicated access is considered a Basic Rate (Permanent) interface. A Basic Rate (Permanent) interface is “up” if the serial layer 1 is “up” for the line. The dedicated access does not have to be “up” for the interface to be considered “up”. A Basic Rate (Permanent) interface is considered to be down if the serial layer 1 is “down” for the line.

Primary Rate (D-Channel)

Each Primary Rate line which contains at least one data link is considered a Primary Rate (D-Channel) interface. A Primary Rate (D-Channel) interface is “up” if at least one data link associated with the interface is “up.” A Primary Rate interface is “down” if none of the data links associated with the interface is “up.”

Primary Rate (Robbed Bit)

Each Primary Rate line that uses Robbed Bit Signaling is considered a Primary Rate (Robbed Bit) interface. A Primary Rate (Robbed Bit) interface is “up” if the serial layer 1 is “up” for the line. A Primary Rate (Robbed Bit) interface is considered to be down if the serial layer 1 is “down” for the line.

Primary Rate (Permanent)

Each Primary Rate line which is used by a dedicated access is considered a Primary Rate (Permanent) interface. A Primary Rate (Permanent) interface is “up” if the serial layer 1 is “up” for the line. The dedicated access does not have to be “up” for the interface to be considered “up”. A Primary Rate (Permanent) interface is considered to be down if the serial layer 1 is “down” for the line.
