IP address

[cmchong]

Can we get info from cisco switch port. Info include which port connected to workstations/equipment are having what ip address?

You can get the MAC address using sh cam

http://cio.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_6_3/cmd_ref/sh_a_c.htm#xtocid8

Then using this MAC address, go to an upstream router and "sh ip arp ".

If you already know the IP address and want to know which port it's on, ping the IP address and do a sh arp on the switch

I have the ip address i want to know which port it's on. when i type "sh arp xx.xxx.70.60", it only shows,

ARP Aging time = 1200 sec

+ - Permanent Arp Entries

* - Static Arp Entries

It doesn't shows the port it's on! BTW the workstation to configure the switch is in difference subnet eg. xx.xxx.90.14, does it method?

Do a "sh mac-address address". That will show you the port the mac address was seen on. This is the switches mac address table, which is fifferent to the ARP table.
