agent
AI MIB Summary
The `agent` MIB module facilitates the monitoring and management of BGP-4 routing processes, specifically tracking session states, neighbor reachability, and routing table statistics within network devices. It provides standardized access to BGP protocol counters and event notifications required for troubleshooting peering failures and validating path selection logic.
The MIB module for BGP-4.

bgpThe MIB module for BGP-4. MODULE-IDENTITY .1.3.6.1.4.1.727.7.2.1.15 |
bgpVersionVector of supported BGP protocol version
numbers. Each peer negotiates the version
from this vector. Versions are identified
via the string of bits contained within this
object. The first octet contains bits 0 to
7, the second octet contains bits 8 to 15,
and so on, with the most significant bit
referring to the lowest bit number in the
octet (e.g., the MSB of the first octet
refers to bit 0). If a bit, i, is present
and set, then the version (i+1) of the BGP
is supported.ro OCTET STRING .1.3.6.1.4.1.727.7.2.1.15.1 |

seconds) this peer has been in the
Established state or how long
since this peer was last in the
Established state. It is set to zero when
a new peer is configured or the router is
booted.ro Gauge32 .1.3.6.1.4.1.727.7.2.1.15.3.1.16 |
bgpPeerConnectRetryIntervalTime interval in seconds for the
ConnectRetry timer. The suggested value
for this timer is 120 seconds.rw INTEGER .1.3.6.1.4.1.727.7.2.1.15.3.1.17 |
bgpPeerHoldTimeTime interval in seconds for the Hold
Timer established with the peer. The
value of this object is calculated by this
BGP speaker by using the smaller of the
value in bgpPeerHoldTimeConfigured and the
Hold Time received in the OPEN message.
This value must be at lease three seconds
if it is not zero (0) in which case the
Hold Timer has not been established with
the peer, or, the value of
bgpPeerHoldTimeConfigured is zero (0).ro INTEGER ( 0 | 3..65535 ) .1.3.6.1.4.1.727.7.2.1.15.3.1.18 |
bgpPeerKeepAliveTime interval in seconds for the KeepAlive
timer established with the peer. The value
of this object is calculated by this BGP
speaker such that, when compared with
bgpPeerHoldTime, it has the same
proportion as what
bgpPeerKeepAliveConfigured has when
compared with bgpPeerHoldTimeConfigured.
If the value of this object is zero (0),
it indicates that the KeepAlive timer has
not been established with the peer, or,
the value of bgpPeerKeepAliveConfigured is
zero (0).ro INTEGER ( 0 | 1..21845 ) .1.3.6.1.4.1.727.7.2.1.15.3.1.19 |
bgpPeerHoldTimeConfiguredTime interval in seconds for the Hold Time
configured for this BGP speaker with this
peer. This value is placed in an OPEN
message sent to this peer by this BGP
speaker, and is compared with the Hold
Time field in an OPEN message received
from the peer when determining the Hold
Time (bgpPeerHoldTime) with the peer.
This value must not be less than three
seconds if it is not zero (0) in which
case the Hold Time is NOT to be
established with the peer. The suggested
value for this timer is 90 seconds.rw INTEGER ( 0 | 3..65535 ) .1.3.6.1.4.1.727.7.2.1.15.3.1.20 |
bgpPeerKeepAliveConfiguredTime interval in seconds for the
KeepAlive timer configured for this BGP
speaker with this peer. The value of this
object will only determine the
KEEPALIVE messages' frequency relative to
the value specified in
bgpPeerHoldTimeConfigured; the actual
time interval for the KEEPALIVE messages
is indicated by bgpPeerKeepAlive. A
reasonable maximum value for this timer
would be configured to be one
third of that of
bgpPeerHoldTimeConfigured.
If the value of this object is zero (0),
no periodical KEEPALIVE messages are sent
to the peer after the BGP connection has
been established. The suggested value for
this timer is 30 seconds.rw INTEGER ( 0 | 1..21845 ) .1.3.6.1.4.1.727.7.2.1.15.3.1.21 |
bgpPeerMinASOriginationIntervalTime interval in seconds for the

seconds.rw INTEGER .1.3.6.1.4.1.727.7.2.1.15.3.1.22 |

UPDATE message was received from the peer.
