I have a customer that is using the MS900 B/P V4.1.0 and Hubwatch V4.1.2 and the question has come up when viewing several screens such as the security screen where the learned addresses are shown, the IP address is never shown. In the find address screen, MAC address are shown but never the IP address. The entire campus is converting to IP and there enternal databases are all based on the IP addressing. The MAC address is not to usefull and the question has been asked why is there no IP info under the column headings, and how do you make it work? Any idea how the IP mapping is done RGDS Richard Szostak NS VAO

The repeater functions you mentioned apply to MAC addresses, not to IP addresses (same thing with bridge address filters). Doing a mac-to-ip translation isn't guaranteed to work. You've got to look in the arp cache for the MAC address. If it's there, you can read the IP address. If it's not, you can't. Doing ip-to-mac is easier, but takes a lot more time. First, look for the IP address in the arp cache. If it's there, read the MAC. If it's not, then go ping the ip address and wait for a reply. Then read the arp cache for the MAC. This is a very time consuming process. HUBwatch does not maintain any mac-to-ip translation tables. Tom Hood | |||||

< HUBwatch does not maintain any mac-to-ip translation tables.> IF this is the case why do we have the IP column heading in the various windows. This would imply that we are going to do this function at some point, if so when? Thanks in advance Richard Szostak NS VAO | |||||

It's there because we're trying to be nice. When performance won't be impacted, or when it's easy to do the translation, we've often done it. On some of the older windows which use code ported from unix to windows, the IP addresses may not be used because the translation was available under unix but not under windows. | |||||
