CISCO-IETF-SCTP-EXT-MIB
AI MIB Summary
The CISCO-IETF-SCTP-EXT-MIB extends Cisco's SCTP management capabilities to monitor Stream Control Transmission Protocol (RFC 2960) session states, association parameters, and stream-specific counters on Cisco network devices. This module provides granular visibility into SCTP transport layer performance and reliability metrics beyond the baseline CISCO-IETF-SCTP-MIB definitions.
An extension to the CISCO-IETF-SCTP-MIB.my used to provide additional information to manage the Stream Control Transmission Protocol (RFC 2960).

cSctpStatRtxChucksNumber of SCTP chunks retransmitted due to the T3 timers
expiring before the packet is acknowledged.ro Counter32 UNITS "chunks" .1.3.6.1.4.1.9.10.76.1.1.1 |
cSctpStatRtxChucksFastNumber of SCTP chunks retransmitted using the
fast-recovery retransmission mechanism specified

was marked unavailable since the start of this association.

the specified number of retransmissions have failed.ro Counter32 .1.3.6.1.4.1.9.10.76.1.1.3 |
cSctpCtrlPurgeTimeoutThe amount of time the SCTP protocol software will wait
before purging an associations TCB. An association TCB
will exist until a management station sets the cSctpAssocState
to deleteTCB or is purge by the protocol implementation. The
protocol implementation will purge an association TCB
using a combination of cSctpCtrlPurgeTimeout and
cSctpCtrlMaxHeld. The cSctpCtrlPurgeTimeout ranges from
the minimum of one hour to roughly one month. The default
value is roughly one day.rw Unsigned32 .1.3.6.1.4.1.9.10.76.1.1.4 |

after they have been marked closed and are no longer
providing service. This limit is used to prevent
excessive waste of resources.rw Unsigned32 .1.3.6.1.4.1.9.10.76.1.1.5 |

the notification generation is enabled.
