What does New Config. not yet ACTIVE mean?

Unanswered Question
May 8th, 2009

I've noticed several routers with IMA that have "New Config. not yet ACTIVE"

What does this mean?

router>sh atm int atm0/0

Interface ATM0/0:

AAL enabled: AAL5 , Maximum VCs: 255, Current VCCs: 0

Maximum Transmit Channels: 0

VCIs per VPI: 256,

Max. Datagram Size: 4528

PLIM Type: DS1, TX clocking: LINE

Cell-payload scrambling: OFF

0 input, 0 output, 0 IN fast, 0 OUT fast, 0 out drop

Avail bw = 1536

New Config. not yet ACTIVE

I have this problem too.

As I suspected, the message is not significant as it does not show the actual state of the

interface. As a matter of fact, that command is completely irrelevant for monitoring the

status of the interface or of the IMA group. Therefore, it cannot even be consider a

cosmetic bug, but simply another instance of the multiple IOS commands that, even though available, don't have any implication in the correct functionality of a feature (the IMA circuit in our particular case)

In an IMA circuit, the individual interfaces don't record any statistics, as they are no

longer considered independent, but part of a group instead. For that reason, "show atm

int atmx/y" or "show int atmx/y" don't show (and are not supposed to show) any traffic


For troubleshooting or monitoring IMA circuits we can use the commands below:

show int atmx/imay

show ima int atmx/y

show ima int atmx/y detail

show ima int atmx/imay

That line is a bogus message from the IOS. Actually, that command is not used for troubleshooting/monitoring IMA circuits.
