I was trying to find the correlation between these ports >and the ports in the bridge MIB itself. Have a look at http://www.nanog.org/mtg-0102/ppt/mibs/sld082.htm In short, dot1dBasePortNum are typically mapped to an ifIndex. Then from ifIndex you can check with either an entity mib or an enterprise mib module to locate the vendor port identifier. >Also, if there is only 32 octets, what goes in this list if more than 256 >ports are on a bridge? PortList TC uses a plain OCTET STRING, it can be larger than 32 octets. See rfc 2578 section 7.1.2.
