The is-name command enables the capability of identifying the host name in an LSP and configures the dynamic host name for the IS-IS system of the local switch. The dynamic hostname is advertised in an LSP packet.
The undo is-name command deletes the dynamic host name configured for the IS-IS system of the local switch.
By default, the IS-IS system of the local switch has no dynamic host name.
| Parameter | Description | Value |
|---|---|---|
symbolic-name |
Specifies a dynamic host name. |
The value is a string of 1 to 64 case-sensitive characters without spaces. When double quotation marks are used around the string, spaces are allowed in the string. |
In most cases, to check information about IS-IS neighbors and LSDBs on an IS-IS switch, you need to use a system ID of a 12-digit hexadecimal number, for example, aaaa.eeee.1234. This representation, however, is complicated and not easy to use. The dynamic host name mapping mechanism is introduced to facilitate maintenance and management of IS-IS networks. The is-name command is used to configure a simple host name for a local switch and enables the switch to advertise it in an LSP.
After the configuration is completed, you can run the display isis name-table command to check the configured hostname.
