Note: This is an RHCE 7 exam objective.
There are two ways to configure aggregated network links between two RHEL systems:
- network bonding: this mode already existed in RHEL 6,
- network teaming: this mode is new to RHEL 7 and offers more options.
Red Hat provides a page comparing the two network links aggregation methods.
Connecting two RHEL systems directly by Ethernet cables is not supported. All connections have to be done through switches.
Concerning the tutorials, all configurations are made between virtual machines. It is also the case in the RHCE 7 exam.
Venkat Nagappan‘s got an interesting video explaining how to Set up Network Teaming & Bonding in CentOS 7 (20min/2015).
