alias <“text”>
Use the alias command to populate the ifAlias OID (Interface Table MIB of RFC 2863) for all physical
interfaces and Frame Relay virtual interfaces when using SNMP management stations.
Syntax Description
<input> Alphanumeric character string (no more than 64 characters) describing the
interface (for SNMP) — must be encased in quotation marks
Default Values
No defaults required for this command.
Command Modes
(config-interface)# Interface Configuration Mode
Functional Notes
The ifAlias OID is a member of the ifXEntry object-type (defined in RFC 2863) used to provide a
non-volatile, unique name for various interfaces. This name is preserved through power cycles. Enter a
string (using the alias command) which clearly identifies the interface.
Usage Examples
The following example defines a unique character string for the T1 interface:
(config)#interface t1 1/1
(config-t1 1/1)#alias “CIRCUIT_ID_23-908-8887-401”
Technology Review
Please refer to RFC 2863 for more detailed information on the ifAlias display string.
