INFINET-BRIDGE-MIB Table View

A table that contains information related to
bridge ports sorted by switch groups they
participate in. Any physical interface can
participate in multiple switch groups and then
it will have multiple port instances (one per
group).

iwBrPortEntry row .1.3.6.1.4.1.3942.1.1.8.1.3.1.1

Information about a specific bridge port.
