alias

This command configures alias names for the device's Virtual Routing and Forwarding (VRF) and IP address interfaces. The alias is used to bind a specific management application (i.e. RADIUS, LDAP, SSH, SNMP, Telnet, Web Interfaces, and Syslog) to a source network interface. If the network interface name is not defined for one of these management interfaces, the default VRF named "main-vrf" (IPv4 or IPv6) is used by default. However, for the voice interface, SIP Interfaces and Media Realms must be assigned a network interface (i.e., alias name of VRF or IP address).

The alias configuration is optional and must be done if the VRF or IP address is used by one of the above-mentioned management applications. If the interface is used for other purposes, such as data routing, the alias of the interface does not need to be configured.
