This problems comes up every so often on IRC and MRTG-like forums, so it deserves further attention. There's a submitted patch for doing it by default: http://sourceforge.net/tracker/index.php?func=detail&aid=1513191&group_id=12694&atid=312694 However, I agree it should rather be a config option instead. Are there any runtime Linux kernel tunables that affect how [transient] interfaces are reported? BTW, please note that Cisco offers a config option for "ifIndex persistence" like this: http://www.cisco.com/en/US/products/hw/routers/ps368/products_configuration_guide_chapter09186a008020b28c.html (This is not exactly the same issue, I know, but may be interesting to some in this context anyway.) +Thomas -- Thomas Anders (thomas.anders at blue-cable.de) ------------------------------------------------------------------------- Using Tomcat but need to do more?
