i'm new to this SNMP stuff and i'm not sure if this is the correct list.
i'd like to determine the hardware address for given a host IP address and
the appropriate router IP address.
i could see a script calling snmpget, but i don't know the correct parameters.
% getmac router_ip host_ip
maybe???
#!/bin/sh
# NAME - getmac
MAC=`snmpget $1 public at.something.something...$2`
echo $MAC
on my cisco, the SNMP value i think i'm interested in is:
at.atTable.atEntry.atPhysAddress.3.1.192.168.1.1 = Hex: 00 00 C0 AF 34 32
3 is the physical interface number
1 is the virtual network number (i think)
192.168.1.1 is the IP address
i can't seem to figure out how to determine the MAC address without knowing
both interface numbers. i'd like to assume that i don't know the number of
interfaces for a given router.
any clues?
thanks,
