Displaying Bidirectional Forwarding Detection information

BigIron RX(config-if-e1000-3/1)# bfd interval 100 min-rx 100 multiplier 3
Syntax: [no] bfd interval <transmit-time> min-rx <receive-time> multiplier <number>
The <transmit-time> variable is the interval in milliseconds between which this router will send a
BFD message to its peer informing it that it is still operational.
This value is specified in milliseconds.
Acceptable values are: 50 - 30000.
The <receive-time> variable is the interval in milliseconds that this router waits to receive a BFD
message from its peer. The router will wait for this interval for the number of times specified in the
<number> variable before determining that the connection to its peer in not operational.
Acceptable values are: 50 - 30000.
NOTE
The transit-time and receive-time variables set with this command are the intervals desired by the
local router. The actual values in use will be the negotiated values.
The <number> variable specifies the number of times in a single sequence that this router will wait
to receive a BFD message from its peer before determining that the connection to that peer is not
operational.
Acceptable values are: 3 - 50.

Number of BFD sessions supported

The device supports a maximum of 100 BFD sessions per system with a maximum number of 20
sessions per interface module. This number is inclusive of the fact that IS-IS and OSPF sessions on
an interface module will include both transmit and receive sessions. Consequently, the 20
sessions per interface module actually corresponds to 40 sessions where each OSPF and IS-IS
session consumes two sessions (one transmit and one receive).

Disabling BFD Syslog messages

Syslog messages are generated for BFD operation. These messages are described in
Syslog
messages use the following command.
BigIron RX(config)# no logging enable bfd
Syntax: [no] logging enable bfd
BFD logging is enabled by default. If you disable BFD logging as shown, you can re-enable it by
using the logging enable bfd command.
Displaying Bidirectional Forwarding Detection information
You can display Bidirectional Forwarding Detection (BFD) information for the router you are
logged-in to and for BFD configured neighbors as described in the following sections.
