find a Switchport with an IP Address
example:
- login to coreswitch
- get the Mac addr
show arp | include 172.23.133.11 Internet 172.23.133.11 56 00d0.c971.2821 ARPA Vlan633
- show the port on witch the mac is located
sh mac address-table | include 00d0.c971.2821 633 00d0.c971.2821 DYNAMIC Te1/0/6
- have a look on witch accessswitch Te1/0/6 is

(just for info) if you want to know more about the neighbor
cdp weis26b241ogost2960-10.itsroot.net
- So, you know now the accessswitch. Now login in to the accessswitch you found on the neighbour table (weis26b241ogost2960-10) and serch it in the mac adress-table
weis26b241ogost2960-10#sh mac address-table | include 00d0.c971.2821 633 00d0.c971.2821 DYNAMIC Gi3/0/14 weis26b241ogost2960-10#
Eh voila, the port is Gi3/0/14 on weis26b241ogost2960-10
