What is the relationship between the SNMP reported "interfaces" (in MIB-II, I think) and the physical ports on a system? I'm having a hard time finding anything on the web.
On a linux system, I've seen the snmpd agent report back "loopback" "eth0" "vlan" ... etc as interfaces, even if the system in question has only a single physical network port. Also, on a network switch, I see the reverse - only 1 "eth0" (and possibly "loopback") are reported for a 4-port router. What baffles me is how the 'interface' abstraction works (in Linux) and how it relates to the actual physical hardware. Could someone please give me pointers to where I can learn more? The only book I have "SNMP, SNMPv2, SNMPv3, and RMON 1 and 2 (3rd Edition) by William Stallings" doesn't speak much on the matter and I suspect its an environment (Linux) thing.
