We have an issue with the current usage of the F5 MIB: the indexes for the interfaces are not an interger but a string (incompatible with the schema of Netdisco). So, I have updated the F5 module with: - usage of the IF-MIB entry anytime where is it possible - creation of a function to map the F5 ID for interfaces with the IF-MIB ID It could solve this issue on Netdisco: https://github.com/netdisco/netdisco/issues/1029
