Trap Buffer Parameters

Parameter	Description
hwSrProtocol	Segment Routing protocol that raised the alarm. 1. OSPF: A conflict within the same process in the OSPF protocol, and the prefix-sid in the conflict state displays OSPF. 2. ISIS: A conflict within the same process in the ISIS protocol, and the prefix-sid in the conflict state displays ISIS. 3. OSPF-SR: A conflict between the OSPF protocol and other protocols, the OSPF protocol is not preferred, or the OSPF protocol conflicts between processes, an OSPF process is not preferred, then the hwSrProtocol of the prefix-sid in the conflict state displays OSPF-SR. 4. ISIS-SR: A conflict between the ISIS protocol and other protocols, the ISIS protocol is not preferred, or the ISIS protocol conflicts between processes, an ISIS process is not preferred, then the hwSrProtocol of the prefix-sid in the conflict state displays ISIS-SR. 5. IGP-SR: A conflict between the label of IGP-SR and BGP-SR, the label of IGP-SR is not preferred, then the hwSrProtocol of the prefix-sid in the conflict state displays IGP-SR.
hwSrProcessId	Process ID
hwSrPrefixSid	Prefix Sid
hwSrPrefixAddress	The Prefix Address configured in the Loopback Interface.
hwSrPrefixAddressMask	Prefix Ip Address Mask.
hwSrConflictType	Conflict type can be Prefix Sid conflict or Prefix conflict. 1. SidConflict 2. PrefixConflict
hwSrConflictState	Conflict state indicates the current conflict state.

Impact on the System

Conflicting routes are not used in SR.

If a prefix conflict occurs, the system selects a single prefix and ignores the same prefixes advertised by the other devices.
If a SID conflict occurs, the system selects a single SID and ignores the same SIDs advertised by the other devices.

Possible Causes

Cause 1: The configuration is incorrect.

Cause 2: The prefix on a loopback interface is the same as the address of a loopback interface on another device.

Cause 3: The SID configured on a loopback interface is the same as the SID on another router.

Procedure

1. If an OSPF prefix-SID conflict occurs, run the ospf prefix-sid { absolute sid-value | index index-value } [ node-disable ] command on the source device to modify the SID configuration.

2. If an IS-IS prefix-SID conflict occurs, run the isis prefix-sid { absolute sid-value | index index-value } [ node-disable ] command on the source device to modify the SID configuration.

3. If an OSPF-SR / ISIS-SR prefix-SID conflict occurs, indicating a conflict between protocols or processes, run the display segment-routing conflict-db segr { { prefix [ dest-ip mask ] } | { sid [ sid ] } } command to find the details of conflict, then run the ospf prefix-sid { absolute sid-value | index index-value } [ node-disable ] command or the isis prefix-sid { absolute sid-value | index index-value } [ node-disable ] command on the source device to modify the SID configuration.

4. Collect alarm and configuration information, and contact technical support engineers.
