ifAdminStatus shows 5 (dormant)

[fred.goetz]

Hello Everybody,

on a Cisco1760 with an Serial Leased Line and a ISDN Backup (bri1/0 configured as backup interface for Serial0/0) i got the following result for a mibbrowse:

ifIndex ifDescr ifAdminStatus ifOperStatus

11 BRI1/0-Physical 5 down

12 BRI1/0-Signaling 5 down

From the IF-MIB definitions there is no state 5 for ifAdminStatus and all other Routers with the like Backup Conf show ifAdminStatus as up and ifOperStatus as dormant (5).

Is this a bug??

If the dialer interface is in spoofing mode, then ifOperStatus should be dormant, and it's correct behavior

[fred.goetz]

Yes, it would be the correct behavior if the ifOperStatus would be dormant, but the ifAdminStatus is dormant (or 5, which is undefined for ifAdminStatus)

Hello, 

What if the port keep changing between 'dormant' -> 'up';.

Is the expected behaviour? Thank you
