This command configuration takes effect only on the local IS-IS device. The value of
symbolic-name will not be added to LSP packets.
If dynamic host name mappings is configured on an IS-IS network, the mappings on
the network overwrite the mappings configured on the local switch.
l (Optional) Enable the output of the IS-IS adjacency status.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
An IS-IS process is created, and the IS-IS view is displayed.
3. Run:
log-peer-change
The output of the adjacency status is enabled.

6.11.3 Configuring IPv6 IS-IS Interfaces
To configure an interface on an IS-IS device to send Hello packets or flood LSPs, IS-IS must
be enabled on this interface.
Context
The level of an IS-IS device and level of an interface together determine the level of a neighbor
relationship. By default, Level-1 and Level-2 neighbor relationships will be established between
two Level-1-2 devices. If only one level of neighbor relationships is required, you can configure
the level of an interface to prevent the establishment of the other level of neighbor relationships.
After IS-IS is enabled on an interface, the interface will automatically send Hello packets,
attempting to establish neighbor relationships. If a peer device is not an IS-IS device or if an
interface is not expected to send Hello packets, suppress the interface. Then this interface only
advertises routes of the network segment where the interface reside, but does not send Hello
packets. This suppression improves the link bandwidth usage.
Procedure
l Configure an IS-IS interface.
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
ipv6 enable
The IPv6 of interface is enabled.
