In a 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C, an interface is a logical named entity. An interface is created by specifying an interface name under the configure>router context. This is the global router configuration context where objects like static routes are defined. An IP interface name can be up to 32 alphanumeric characters long, must start with a letter, and is case-sensitive; for example, the interface name ‟1.1.1.1” is not allowed, but ‟int-1.1.1.1” is allowed.
To create an interface on a 7210 SAS router, the basic configuration tasks that must be performed are as follows:
Assign a name to the interface.
Associate an IP address with the interface.
Associate the interface with a network interface or the system interface.
Associate the interface with a system or a loop-back interface.
Configure appropriate routing protocols.
A system interface and network interface should be configured.
