WAN Interface with an OperStatus of "TESTING"

can anyone explain how a wan circuit can go from 'up' to a state of 'testing'? i don't think this is done through the ios, such as admindown, is it?

can the carrier/provider place the circuit in this state?

here's some oid/mib info:

Object

ifOperStatus

OID

1.3.6.1.2.1.2.2.1.8

Type

INTEGER

Permission

read-only

Status

current

Values

1 : up

2 : down

3 : testing

4 : unknown

5 : dormant

6 : notPresent

7 : lowerLayerDown

MIB

IF-MIB ; - View Supporting Images

Description

"The current operational state of the interface. The

testing(3) state indicates that no operational packets can

be passed. If ifAdminStatus is down(2) then ifOperStatus

should be down(2). If ifAdminStatus is changed to up(1)

then ifOperStatus should change to up(1) if the interface is

ready to transmit and receive network traffic; it should

change to dormant(5) if the interface is waiting for

external actions (such as a serial line waiting for an

incoming connection); it should remain in the down(2) state

if and only if there is a fault that prevents it from going

to the up(1) state; it should remain in the notPresent(6)

state if the interface has missing (typically, hardware)

components."

thanks,

Re: WAN Interface with an OperStatus of "TESTING"

If the interface is placed in a loopback, then its OperStatus will be testing. The provider or you may have looped the interface for diagnostic purposes.
