bfd enable Enables BFD on all interfaces on the switch. Syntax Parameters Default Command Mode Usage Information Example bfd enable None BFD is disabled. CONFIGURATION Before you configure BFD for static routing or a routing protocol, enable BFD globally on each router in a BFD session. To globally disable BFD on all interfaces, enter the no bfd enable command. OS10(config)# bfd enable Supported releases 10.4.1.0 or later bfd interval Configures parameters for all BFD sessions on the switch. Syntax bfd interval milliseconds min_rx milliseconds multiplier number role {active | passive} Parameters • interval milliseconds - Enter the time interval for sending control packets to BFD peers, from 100 to 1000. Dell EMC recommends using more than 100 milliseconds. • min_rx milliseconds - Enter the maximum waiting time for receiving control packets from BFD peers, from 100 to 1000. Dell EMC recommends using more than 100 milliseconds. • multiplier number - Enter the number of consecutive packets that must not be received from a BFD peer before the session state changes to Down, from 3 to 50. • role {active | passive} - Enter active if the router initiates BFD sessions. Both BFD peers can be active at the same time. Enter passive if the router does not initiate BFD sessions, and only responds to a request from an active BFD to initialize a session. Default The time interval for sending control packets to BFD peers is 200 milliseconds. The maximum waiting time for receiving control packets from BFD peers is 200 milliseconds. The number of consecutive packets that must be received from a BFD peer is 3. The BFD role is active. Command Mode Usage Information Example CONFIGURATION Use the bfd interval command to configure global BFD session settings. To configure the BFD parameters used in sessions established with neighbors discovered by an L3 protocol, use the bfd all-neighbors command. To remove the configured global settings and return to the default values, enter the no version of the command. OS10(config)# bfd interval 250 min_rx 300 multiplier 4 role passive Supported releases 10.4.1.0 or later 292 Layer 3
