Reliability Configuration
BFD Configuration
\[Command] show bfd peer ip-address show bfd peers show bfd peers brief \[Purpose] View BFD session information \[View] System view \[Use Cases] \[Command] show bfd peers counters clear bfd peers counters \[Purpose] View BFD session statistics \[View] System view \[Use Cases] \[Command] bfd \[Purpose] Enter BFD configuration view \[View] System configuration view \[Use Cases] \[Command] peer ip-address \[{multihop|local-address ip-address |interface interface-type interface-name }] no peer ip-address \[{multihop|local-address ip-address |interface interface-type interface-name }] \[Purpose] Create BFD session binding information and enter BFD-peer view \[Parameter] \[View] BFD View \[Use Cases] \[Command] profile profile-name no profile profile-name \[Purpose] Configure BFD policy group/bind specified policy group to peer \[Parameter] \[View] BFD View, BFD-peer View \[Usage Scenario] When creating a large number of Bidirectional Forwarding Detection (BFD) sessions on a device, configuring peer policies one by one can significantly reduce configuration efficiency. Therefore, configuring BFD policy groups and then binding the policy group to peers can effectively streamline the configuration process.
Monitor Link Configuration
\[Command] show monitor-link \[Purpose] View interface linkage group configuration \[View] System view \[Use Cases] \[Command] monitor-link-group group-id delay-time no monitor-link-group group-id \[Purpose] Create interface linkage groups \[Parameter] \[View] System configuration view \[Usage Scenario] The interface bundling group synchronizes the monitoring of the upstream link to make corresponding settings on the downstream link. This ensures that faults in the upstream link are quickly communicated to the downstream devices, thereby triggering actions to prevent prolonged traffic loss due to upstream link failures.
VRRP Configuration
\[Command] show vrrp interface {vlan|ethernet|link-aggregation ID } show vrrp ID \[Purpose] View detailed information about the VRRP backup group \[View] System view \[Use Cases] \[Command] show vrrp summary \[Purpose] View VRRP backup group information \[View] System view \[Use Cases] \[Command] vrrp ID \[version ID ] \[Purpose] Create a VRRP backup group and specify the VRRP version. \[View] Interface view \[Parameter] \[Use Cases] \[Command] vrrp ID priority VALUE \[Purpose] Configure the priority of the device in the VRRP backup group \[View] Interface view \[Parameter] \[Use Cases] \[Command] vrrp ID advertisement-interval VALUE \[Purpose] Configure the interval for sending VRRP advertisement packets \[View] Interface view \[Parameter] \[Usage Scenario] The master device periodically sends VRRP advertisement packets to the backup devices within the group to notify them of its normal operation.
