You are looking for SNMP. It's probably the only way to get unified
interface for heterogeneous devices, in particular to ARP tables.
Unfortunately that's only the protocol, I cannot recommend you any
piece of software which uses it, although probably every piece of
monitoring software offers you that functionality. I've not used it,
but the one that I know that closer resemebles a network-only
management one is opennms (http://www.opennms.org/).
