bfd

To set the baseline Bidirectional Forwarding Detection (BFD) session parameters on an interface, use the bfd
interface configuration mode. To remove the baseline BFD session parameters, use the no form of this
command
bfd interval milliseconds min_rx milliseconds multiplier multiplier-value
no bfd interval milliseconds min_rx milliseconds multiplier multiplier-value
Syntax Description

Release
Cisco IOS XE Denali 16.3.1
Usage Guidelines
The bfd command can be configured on SVI, Ethernet and port-channel interfaces.
If BFD runs on a port channel interface, BFD has a timer value restriction of 250 * 3 milliseconds.
The bfd interval configuration is not removed when:
• an IPv4 address is removed from an interface
• an IPv6 address is removed from an interface
• IPv6 is disabled from an interface
• an interface is shutdown
• IPv4 CEF is disabled globally or locally on an interface
Specifies the rate, in milliseconds, at which BFD control packets will be sent to
BFD peers. The valid range for the milliseconds argument is from 50 to 9999.
Specifies the rate, in milliseconds, at which BFD control packets will be expected
to be received from BFD peers. The valid range for the milliseconds argument
is from 50 to 9999.
Specifies the number of consecutive BFD control packets that must be missed
from a BFD peer before BFD declares that the peer is unavailable and the Layer
3 BFD peer is informed of the failure. The valid range for the
multiplier-valueargument is from 3 to 50.
