Abstract
Example methods, apparatuses, and systems are presented for determining a physical (real) topology of an Ethernet type network, including mapping physical switches arranged in a multi-chassis link aggregation group (MC-LAG). Spanning tree protocol (STP) data is obtained via a combination of SNMP queries or SSH/telnet connectors. The STP data and MAC addresses are collected initially for all the switches in the mapping criteria. After collecting this data, pairs of switches are formed (e.g., randomly) and the collected data is correlated and stored according to the set of rules described in embodiments of the present disclosure in order to find switch to switch links.
