In older IOS versions you had a limited number of Interface Descriptor Blocks, or IDBs. On our 7513 using an RSP4 I believe the limit was 300 or so, which is pretty easy to run up against if you try. :-)
In newer IOS releases--I think after 12.0--the limit was raised to over 1000, if I remember right. Regardless, it's more than we'll ever use here. HTH, John >>> "Maccubbin, Duncan" 12/7/01 12:32:24 PM >>> I have to disagree here. We had a fairly loaded 7200 fail due to having too many sub-interfaces. I dug around on Cisco's site and found a document that broke down the amount of memory each sub-interface used. (no, I can't find it now) We actually got quite a few more than they had it rated for but there are memory concerns all the same. If your 2600 doesn't have a lot of memory it will be limited. How many sub-interfaces you talking about? How much memory does the box have? You may want to consult Cisco if you are going over 50 or so. Just my $0.02.
