Linux – snmpd configuration to enable BRIDGE-MIB or Q-BRIDGE-MIB

bridgelinuxsnmpswitchvlan

All the Ethernet switches and access points on my network provide snmp access to the bridge learn table except for my linux-based bridge.

Does net-snmp support exporting the bridge forwarding database via snmp? This is BRIDGE-MIB defined in RFC 1493 (or even better, Q-BRIDGE-MIB defined in RFC2674). What snmpd configuration options are needed to make this work? Do I need to build and deploy some of the optional agents?

Is there a better way to remotely gather the information displayed by brctl showmacs br0 (specifically, the list of learned MAC addresses and the port number via which each is reachable)?

I also found this man page: http://linux.die.net/man/1/snmp-bridge-mib

It might be another implementation that might even work.

It seems OpenVSwitch does better in that aspect.

Your alg looks good to me. I wish it didn't have to be so complicated. Have you tried, e.g., just checking ipRouteTable?

As for DHCP that is either ipNetToMediaType or ipNetToPhysicalType with a value: INTEGER: dynamic(3).

There is no standard MIB that contains the name servers.

Since you are connecting with the public commit you are limited to only the mibs define by systemonly. You may want to remove the -V systemonly bit.
