Reference: BFD Details
To see the following BFD information
for a virtual router, you can refer Step View
BFD summary and details.
Name | Value (Example) | Description |
---|---|---|
Session ID | 1 | ID number of the BFD session. |
Interface | ethernet1/12 | Interface you selected where BFD is running. |
Protocol | STATIC(IPV4) OSPF | Static route (IP address family of static route)
and/or dynamic routing protocol that is running BFD on the interface. |
Local IP Address | 10.55.55.2 | IP address of interface. |
Neighbor IP Address | 10.55.55.1 | IP address of BFD neighbor. |
BFD Profile | default *(This BFD session has multiple
BFD profiles. Lowest ‘Desired Minimum Tx Interval (ms)’ is used
to select the effective profile.) | Name of BFD profile applied to the interface. Because
the sample interface has both a static route and OSPF running BFD
with different profiles, the firewall uses the profile with the
lowest Desired Minimum Tx Interval. In this example,
the profile used is the default profile. |
State (local/remote) | up/up | BFD states of the local and remote BFD peers.
Possible states are admin down, down, init, and up. |
Up Time | 2h 36m 21s 419ms | Length of time BFD has been up (hours, minutes,
seconds, and milliseconds). |
Discriminator (local/remote) | 1391591427/1 | Discriminators for local and remote BFD peers. |
Mode | Active | Mode in which BFD is configured on the interface:
Active or Passive. |
Demand Mode | Disabled | PAN-OS does not support BFD Demand Mode,
so it is always in Disabled state. |
Multihop | Disabled | BFD multihop: Enabled or Disabled. |
Multihop TTL | TTL of multihop; range is 1-254. Field is empty
if Multihop is disabled. | |
Local Diag Code | 0 (No Diagnostic) | Diagnostic codes indicating the reason for
the local system’s last change in state: 0—No Diagnostic 1—Control
Detection Time Expired 2—Echo Function Failed 3—Neighbor
Signaled Session Down 4—Forwarding Plane Reset 5—Path
Down 6—Concatenated Path Down 7—Administratively Down 8—Reverse
Concatenated Path Down |
Last Received Remote Diag Code | 0 (No Diagnostic) | Diagnostic code last received from BFD peer. |
Transmit Hold Time | 0ms | Hold time (in milliseconds) after a link comes
up before BFD transmits BFD control packets. A hold time of 0ms
means to transmit immediately. Range is 0-120000ms. |
Received Min Rx Interval | 1000ms | Minimum Rx interval received from the peer;
the interval at which the BFD peer can receive control packets.
Maximum is 2000ms. |
Negotiated Transmit Interval | 1000ms | Transmit interval (in milliseconds) that the
BFD peers have agreed to send BFD control packets to each other.
Maximum is 2000ms. |
Received Multiplier | 3 | Detection time multiplier value received from
the BFD peer. The Transmit Time multiplied by the Multiplier equals
the detection time. If BFD does not receive a BFD control packet
from its peer before the detection time expires, a failure has occurred.
Range is 2-50. |
Detect Time (exceeded) | 3000ms (0) | Calculated detection time (Negotiated Transmit
Interval multiplied by Multiplier) and the number of milliseconds
the detection time is exceeded. |
Tx Control Packets (last) | 9383 (420ms ago) | Number of BFD control packets transmitted
(and length of time since BFD transmitted the most recent control packet). |
Rx Control Packets (last) | 9384 (407ms ago) | Number of BFD control packets received (and
length of time since BFD received the most recent control packet). |
Agent Data Plane | Slot 1 - DP 0 | On PA-7000 Series firewalls, the dataplane
CPU that is assigned to handle packets for this BFD session. |
Errors | 0 | Number of BFD errors. |
Last Packet Causing State
Change | ||
Version | 1 | BFD version. |
Poll Bit | 0 | BFD poll bit; 0 indicates not set. |
Desired Min Tx Interval | 1000ms | Desired minimum transmit interval of last
packet causing state change. |
Required Min Rx Interval | 1000ms | Required minimum receive interval of last
packet causing state change. |
Detect Multiplier | 3 | Detect Multiplier of last packet causing state
change. |
My Discriminator | 1 | Remote discriminator. A discriminator is a
unique, nonzero value the peers use to distinguish multiple BFD
sessions between them. |
Your Discriminator | 1391591427 | Local discriminator. A discriminator is
a unique, nonzero value the peers use to distinguish multiple BFD
sessions between them. |
Diagnostic Code | 0 (No Diagnostic) | Diagnostic code of last packet causing state
change. |
Length | 24 | Length of BFD control packet in bytes. |
Demand Bit | 0 | PAN-OS does not support BFD Demand mode,
so Demand Bit is always set to 0 (disabled). |
Final Bit | 0 | PAN-OS does not support the Poll Sequence,
so Final Bit is always set to 0 (disabled). |
Multipoint Bit | 0 | This bit is reserved for future point-to-multipoint
extensions to BFD. It must be zero on both transmit and receipt. |
Control Plane Independent Bit | 1 |
|
Authentication Present Bit | 0 | PAN-OS does not support BFD Authentication,
so the Authentication Present Bit is always set to 0. |
Required Min Echo Rx Interval | 0ms | PAN-OS does not support the BFD Echo function,
so this will always be 0ms. |
