I’ve spent the last week or so playing with Cacti (after telling myself to do so for quite some time), and one of the goals was to get real graphing of data on my Airport Extreme (Dual-Band, A1301, March 2009). The issue is, there is very little information online as to SNMP mappings on this base station. What interface is the WAN, which are the wireless, etc. After some trial and error (and help of iEyeNet) I have figured that information out.
The following interfaces are in SNMP, and their corresponding real life equivalents.
|gec0||Switch||Switch as a whole. I think only LAN ports, excluding WAN|
|ath0||802.11 5ghz||5ghz Wireless Interface|
|ath1||802.11 2.4ghz||2.4ghz Wireless Interface|
|lo0||Loopback||Loopback adapter. Should show ALL traffic|
|wlan0||802.11 5ghz||5ghz Wireless Interface. Again.|
|wlan1||802.11 2.4ghz||2.4ghz Wireless Interface. Again.|
|vlan1||WAN||WAN port, assuming NAT is enabled|
|bridge0||eth-wlan bridge||Wireless to Ethernet Bridge|
|stf0||Six-to-Four bridge||Bridges IPv6 to IPv4|
Now some of these may change if you turn off NAT, or don’t have 2.4ghz or 5ghz wireless enabled. But this should allow you to see WAN traffic, wireless traffic, and LAN traffic. The big question I’m not sure about is if “gec0” does or does not include the WAN traffic.
