TRILL uses the IS-IS MIB to provide the TRILL object management function for NMS. Because the MIB
objects defined in the IS-IS MIB are single-instance management objects, NMS cannot manage IS-IS and
TRILL at the same time. According to the management for multiple OSPF instances defined in RFC 4750,
you can set a context name for the SNMP object for managing TRILL. In this way, the SNMP requests for
managing IS-IS and the SNMP requests for managing TRILL from NMS can be distinguished. Because the
context name is a concept specific to SNMPv3, the community names are mapped to context names for
distinguishing different protocols in SNMPv1/v2c.
To configure SNMP for TRILL:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable SNMP
notification sending
for TRILL.
snmp-agent trap enable trill
[ adjacency-state-change | area-mismatch |
buffsize-mismatch | id-length-mismatch |
lsdboverload-state-change | lsp-parse-error |
lsp-size-exceeded | max-seq-exceeded |
maxarea-mismatch | new-drb | own-lsp-purge
| protocol-support | rejected-adjacency |
skip-sequence-number | topology-change |
version-skew ] *
By default, SNMP
notification sending is
enabled for TRILL.
3. Enter TRILL view. trill N/A
4. Configure the context
name for the SNMP
object for managing
TRILL.
snmp context-name context-name
By default, no context name
is set for the SNMP object for
managing TRILL.
Configuring TRILL GR
Graceful Restart (GR) ensures the continuity of packet forwarding when a protocol restarts or an
active/standby switchover occurs. The device on which a protocol restarts or an active/standby
switchover occurs advertises the restart status to the neighbors, and allows the neighbors to re-establish
connections. GR involves the following roles:
• GR restarter—Graceful restarting router. It must be GR capable.
• GR helper—A neighbor of the GR restarter. It helps the GR restarter to complete the GR process.
To configure TRILL GR:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter TRILL view. trill N/A
3. Enable GR for TRILL. graceful-restart By default, GR is disabled for TRILL.
4. (Optional.) Configure
the GR interval for TRILL.

The default setting is 300 seconds.
