This text field, 1 to 15 characters, holds the case-sensitive name assigned to a virtualization context on the H3C device, and the description specifically notes the name can't be changed once the context has been created. An administrator sets this name at context creation time to something meaningful, since renaming later isn't supported and the context would need to be deleted and recreated to change its name. For example, a service provider might name a context "CustomerA-VS" to make clear which customer's isolated configuration domain it represents.
