![]() I decided to use v1 for everything and monitor at 1 minute intervals to prevent counter wrap. ![]() It only supports SNMPv2c for mgi0 and mgi1! If you want to monitor the other ports you have to use SNMPv1.Manually setting the config to GigE makes for pretty graphs. This makes tools like the MRTG cfg maker generate bad configs. In SNMP it reports all the GigE interfaces are 10Mbps.I have a separate thread in another forum where I am trying to track that down. I don't yet know if this is the fault of the Time Capsule or the result of HE's tunnel config. It only applies to Active FTP, passive mode is your friend. The built in NAT handles FTP in a way that generates a warning, but will probably work for most people.It has no trouble with other large DNS records, which is odd. For some reason the DNS server in the box won't pass TXT records over 1500 bytes.I ran the ICSI Netalyzer ( ) against it (with an HE tunnel configured for IPv6 connectivity) and it basically passed with flying colors. Lastly, there's a SATA port to the disk in a Time Capsule. Lo0 is the loopback, not shown in the diagram. Again, this would be traffic with no overhead, then as the packets go out mgi0 they would count there with the tunnel overhead. Gif0 is 6in4 tunneling, if you have for instance a tunnel broker tunnel. Pppoe0 is for tunneling PPP over Ethernet, if you use that on the WAN port, basically in that case mgi0 would be with PPPoE overhead, and pppoe0 would be without. Traffic between any two of these three will pass the bridge interface. Traffic on these interfaces increases as traffic increases on the wlan0/wlan1 interfaces, but at a much lower rate.īridge0 is a software bridge that sits between wlan0, wlan1, and mgi1 briding the WiFi's and LAN ports together. They report outbound traffic only, never inbound. Wlan0/wlan1 are the data connections for the 2.4Ghz and 5Ghz radios, respectively.īwl0/bwl1 appear to be some sort of managmenet interface for the radios. The other three ports are exposed on the back of the unit as the LAN ports. Mgi1 is connected to an internal 4 port GigE switch that appears to not have any individual pollable ports via SNMP. Attached to this post is a block diagram of the architecture of one of these boxes. I did some trial and error, and figuring it out. The issue I found was with monitoring, no one had documented how the various interfaces were set up. Instructions to set them up for IPv6 are readily available (TunnelBroker will tell you how!), so no need to rehash that set of steps. The unit I set up is a 4th Gen, and is likely the same (with the addition of a hard drive) as the Apple Extreme Base Station. I set up an Apple Time Capsule recently and I'm very pleased with the results.
