Configuring BFD Quick Steps for Configuring BFD
OmniSwitch AOS Release 6 Network Configuration Guide September 2009 page 30-5
Note. Demand mode is not supported. The default operational mode is Asynchronous with the echo func-
tion enabled. However, Static Routing and VRRP protocol support BFD in the echo-only operational
mode.
12 Configure the global BFD echo packet time interval using the ip bfd-std echo interval command. This
command defines a default echo packet time value that is automatically applied when a BFD interface is
created. For example:
-> ip bfd-std echo-interval 500
13 Configure the echo time interval for a specific BFD interface using the ip bfd-std interface echo-
interval command. The echo time interval value set with this command overrides the global echo time
interval configured for the switch. For example:
-> ip bfd-std interface bfd-vlan-101 echo-interval 500
14 Configure the global Layer 2 hold-down (convergence) timer value using the ip bfd-std l2-hold-timer
command. This command defines a default timer value that is automatically applied when a BFD inter-
face is created. For example:
-> ip bfd-std l2-hold-timer 500
15 Configure the Layer 2 hold-down (convergence) timer value for a specific BFD interface using the ip
bfd-std interface l2-hold-timer command. The timer value set with this command overrides the global
timer value configured for the switch. For example:
-> ip bfd-std interface bfd-vlan-101 l2-hold-timer 500
16 Enable the administrative status of a BFD interface using the ip bfd-std interface status command.
For example:
-> ip bfd-std interface bfd-vlan-101 status enable
Note. BFD parameters are not configurable once the BFD administrative status is enabled on the interface.
17 Globally enable the BFD protocol for the switch using the ip bfd-std status command. For example:
-> ip bfd-std status enable
Note. Optional. Verify the BFD interface status and configuration using the show ip bfd-std interfaces
command. For example:
-> show ip bfd-std interfaces bfd-vlan-101
