What is ctIfPortType?

This read-only object identifier names the specific port media type, such as EPIM or TPIM, from the vendor's ctron-oids tree. An admin uses it to identify exactly which physical media module a port sits on for inventory or troubleshooting. For example, ctIfPortType returning the OID for TPIM tells the admin this port sits on a twisted-pair interface module rather than a fiber EPIM module.

Examples
