Folks,

When I was playing with arp command a nd parameters , I configured my switch
with three vlans (1,2,3) and put a router ethernet interface in f0/18 on my
switch and execute the command sh ip arp and it gave me the
output:

UP#sh ip arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  3.1.1.1                 -   000c.301f.2780  ARPA   Vlan1
Internet  5.1.1.1                 -   000c.301f.2780  ARPA   Vlan2
Internet  100.1.1.1               -   000c.301f.2780  ARPA   Vlan100
Internet  3.1.1.200               4   0000.0c3d.c70b  ARPA   Vlan1

Is there a way to know which mac-address and/or what is the IP of the device
connected  to certain Ethernet port on the switch!!?

thanx
