We see the same issue with ifconfig with 1000 DLCIs with no IP addresses assigned at all. Its something in the way that ifconfig gets the info...ifconfig on other OSs with similar setups return with no additional delay. I could understand if you did a -a, but there is really no good explanation of why an ifconfig on a specific interface would take so long to get the info. I reported it a while back without much interest. DB - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
