Time Capsule Interface List

Per my other question on monitoring network throughput , I now have a series of graphs, some of which are distinctly non-obvious as to what they are. Is there documentation on what every interface on a Time Capsule (in this case, current generation, 1TB Wireless N Base Station), pollable via SNMP are? Here is the list that is available: gec0 ath0 ath1 wlan0 wlan1 wlan2 wlan3 vlan1 rxq0
