        server      => 'https://fmcrestapisandbox.cisco.com',
        user        => 'admin',
        passwd      => '$password',
        clientattrs => { timeout => 30 },

        'Net::Cisco::FMC::v1::Role::FixAccessruleLiterals');

DESCRIPTION

Cisco FMC 6.3.0 introduced support for FQDN objects which broke literal IPv4 host and network objects via the accessrules REST API. Even worse not only are the types of the replies incorrect but updating an existing rule or creating a new one based on a reply silently swallows literal host and network objects which have their type set to FQDN.

This role works around this bug by modifying the reply of "Net::Cisco::FMC::v1/get_accessrule" and "list_accessrules" in Net::Cisco::FMC::v1 and replacing 'FQDN' with 'Network'.

This is how an accessrule API response looks like in 6.2.3.7:
