What does the Type value in OpenAPI output for Interface Items represent?

Environment

All supported CA Performance Management releases

Resolution

These are the values the interfaces are providing from queries to the ifType MIB OID.

We see type values 6, 18, and 32 listed here. These are defined as:

• ethernet-csmacd(6), 
• ds1(18), 
• frame-relay(32) 

Additional Information

For ifType we see per this sample page that shows us the possible values that can be seen in the ifType MIB OID for interfaces.
 

The following are the first 32 common types in use. There are more than 32 possible types that can be seen. Review the sample page here for more type definitions.
