Configuring Snmp Notifications And Context For Evi Is-Is; Configuring Graceful Restart For An Evi Is-Is Process - HP FlexFabric 12900 Series Configuration Manual

Step
1. Enter system view.
2. Enter EVI IS-IS process view.
3. Enable adjacency change
logging.

Configuring SNMP notifications and context for EVI IS-IS

To report critical EVI IS-IS events to an NMS, enable SNMP notifications for EVI IS-IS. For EVI IS-IS event
notifications to be sent correctly, you must also configure SNMP as described in Network Management
and Monitoring Configuration Guide.
In addition to the private EVI IS-IS MIB, EVI IS-IS shares the standard IS-IS MIB with IS-IS and other
protocols that use IS-IS in the control plane. For SNMP to correctly identify a protocol's management
information in the standard IS-IS MIB, you must configure a unique context for each of these protocols. If
a protocol supports multiple processes, you must assign a unique context to each process.
The context names must be unique among all the protocols and their processes.
Context is a method introduced to SNMPv3 for multiple instance managements. For SNMPv1/v2c, you
must specify a context name as a community name for protocol identification.
To configure SNMP notifications and context for an EVI IS-IS process:
Step
1. Enter system view.
2. Enable EVI IS-IS
notifications.
3. Enter EVI IS-IS process
view.
4. Configure an SNMP
context name for EVI IS-IS.

Configuring Graceful Restart for an EVI IS-IS process

Enable Graceful Restart for the peer EVI IS-IS processes at two ends of an EVI tunnel to guarantee
nonstop forwarding while the peer EVI IS-IS processes are re-establishing their adjacency after a process
restart or active/standby switchover occurs.
