query [7:44904]
Hi, Is it possible to get the IP addresses of all the boxes attached to a port in the switch. If there are 2 boxes attached to a hub and that hub is attached is attached to a switch. Now is it possible to get the IP addresses of those 2 boxes by just looking at the switch... thru SNMP or some other means.. Please pardon me if my questions seem illogical :-) Thanks, Ashish Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=44904t=44904 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Hi, You may want to download a trial version of fluke software, Network Inspector, from http://www.flukenetworks.com/us/LAN/Monitoring+Analysis+Diagramming/Network+Inspector/_software.htm, which will tell all the ip address connected a port in the switch. I don't know there is a built-in command used to show all the ip connected to a single port. If you find one, please tell me.

I always go to the switch and look through the CAM table. I pull out the MAC Addresses associated with a port, then I take those MAC addresses to a host that has an ARP database, arp -a | grep in unix, or show ip arp on IOS. Basically, you could have your host ping all known IP addresses so it ARP's them, then query the CAM database on your switch for those particular MAC addresses. Of course, if someone else knows a better way, feel free to add. :) -- Jeff Harris - Cisco/Unix Engineer CCNA, CCNP Routing, Remote Access Passed On Thu, May 23, 2002 at 07:21:24PM -0400, ashish wrote: Hi, Is it possible to get the IP addresses of all the boxes attached to a port in the switch.

Yeah.. in the switch, get the MACs of all of the devices attached to that port, then go to the router that acts as the gateway for that subnet that those devices are in, and do a 'show arp' then (hopefull you have a good terminal program to) search through and find the IPs that go with the MACs. I don't quite know what you're saying about have your host ping all known IPs so it's ARPs them... If you're not on the same IP subnet, all your ARP is going to get you is the MAC of your gateway router, and either way, unless you're on the same switch with the target devices, pinging or ARPing or whatever isn't going to pull the target MACs into the CAM on your switch Mike W.
