CISCO-HSRP-EXT-MIB
AI MIB Summary
The CISCO-HSRP-EXT-MIB extends the standard Cisco Hot Standby Router Protocol (HSRP) monitoring capabilities to expose extended state variables and counters for HSRP groups on Cisco IOS devices. This module enables granular visibility into HSRP session transitions, priority adjustments, and preemption behaviors beyond the baseline metrics defined in RFC 2281.
The Extension MIB module for the CISCO-HSRP-MIB which is based on RFC2281.

cHsrpExtIfTrackedTableA table containing information about tracked interfaces per
HSRP group. SEQUENCE OF CHsrpExtIfTrackedEntry .1.3.6.1.4.1.9.9.107.1.1.1 |
cHsrpExtIfTrackedEntryThe cHsrpExtIfTrackedEntry allows an HSRP group
interface to track one or more interfaces. Weight(priority)
is given to each and every interface tracked. When a tracked
interface is unavailable, the HSRP priority of the router is
decreased. i.e cHsrpGrpPriority value assigned to an HSRP
group will reduce by the value assigned to
cHsrpExtIfTrackedPriority. This reduces the likelihood
of a router with a failed key interface becoming the
active router.
Setting cHsrpExtIfTrackedRowStatus to active starts
the tracking of cHsrpExtIfTracked by the HSRP group.
The value of cHsrpExtIfTrackedRowStatus may be set
to destroy at any time.
Entries may not be created via SNMP without explicitly setting
cHsrpExtIfTrackedRowStatus to either 'createAndGo'
or 'createAndWait'.
Entries can be created and modified via the management
protocol or by the device's local management interface.
If the row is not active, and a local management interface
command modifies that row, the row may transition to active
state.
A row entry in the cHsrpExtIfTrackedTable can not be created
unless the corresponding row in the cHsrpGrpTable has been
created. If that corresponding row in cHsrpGrpTable is
deleted, the interfaces it tracks also get deleted.
A row which is not in active state will timeout after a
configurable period (five minutes by default). This timeout
period can be changed by setting cHsrpConfigTimeout. CHsrpExtIfTrackedEntry .1.3.6.1.4.1.9.9.107.1.1.1.1 |
cHsrpExtIfTrackedIndex into the cHsrpExtIfTrackedTable for the
corresponding { ifIndex, cHsrpGrpNumber } pair i.e for an
HSRP group. This is the ifIndex of the tracked interface. InterfaceIndex -- Rsyntax Integer32 .1.3.6.1.4.1.9.9.107.1.1.1.1.1 |
cHsrpExtIfTrackedPriorityPriority of the tracked interface for the corresponding
{ ifIndex, cHsrpGrpNumber } pair. In the range of 0 to 255, 0
is the lowest priority and 255 is the highest. When a tracked
interface is unavailable, the cHsrpGrpPriority of the router
is decreased by the value of this object instance (If the
cHsrpGrpPriority is less than the
cHsrpExtIfTrackedPriority, then the HSRP priority
becomes 0). This allows a standby router to be configured
with a priority such that if the currently active router's
priority is lowered because the tracked interface goes down,
the standby router can takeover.rw Unsigned32 .1.3.6.1.4.1.9.9.107.1.1.1.1.2 |
cHsrpExtIfTrackedRowStatusThe control that allows modification, creation, and deletion
of entries. For detailed rules see the DESCRIPTION for
cHsrpExtIfTrackedEntry.rw RowStatus -- Rsyntax INTEGER { -- active(1), -- notInService(2), -- notReady(3), -- createAndGo(4), -- createAndWait(5), -- destroy(6) -- } .1.3.6.1.4.1.9.9.107.1.1.1.1.3 |
cHsrpExtSecAddrTableA table containing information about secondary HSRP IP
Addresses per interface and group. SEQUENCE OF CHsrpExtSecAddrEntry .1.3.6.1.4.1.9.9.107.1.1.2 |
cHsrpExtSecAddrEntryThe CHsrpExtSecAddrEntry allows creation of secondary
IP Addresses for each cHsrpGrpEntry row.
Secondary addresses can be added by setting
cHsrpExtSecAddrRowStatus to be active. The value of
cHsrpExtSecAddrRowStatus may be set to destroy at any
time.
Entries may not be created via SNMP without explicitly setting
cHsrpExtSecAddrRowStatus to either 'createAndGo'
or 'createAndWait'.
Entries can be created and modified via the management
protocol or by the device's local management interface.
If the row is not active, and a local management interface
command modifies that row, the row may transition to active
state.
A row which is not in active state will timeout after a
configurable period (five minutes by default). This timeout
period can be changed by setting cHsrpConfigTimeout.
Before creation of a cHsrpExtSecAddrEntry row,
either cHsrpGrpConfiguredVirtualIpAddr or
cHsrpGrpLearnedVirtualIpAddr must have a valid IP Address.
This is because a secondary ip address cannot be created
unless the primary ip address has already been set.
To create a new cHsrpExtSecAddrEntry row, a management
station should choose the ifIndex of the interface which is to
be added as part of an HSRP group. Also, an HSRP group number
and a cHsrpExtSecAddrAddress should be chosen.
Deleting a {ifIndex, cHsrpGrpNumber} row in the
cHsrpGrpTable will delete all corresponding
rows in the cHsrpExtSecAddrTable.
Deleting a primary address value in the cHsrpGrpEntry row
will delete all secondary addresses for the same
{ifIndex, cHsrpGrpNumber} pair. CHsrpExtSecAddrEntry .1.3.6.1.4.1.9.9.107.1.1.2.1 |
cHsrpExtSecAddrAddressA secondary IpAddress for the {ifIndex, cHsrpGrpNumber} pair.
As explained in the DESCRIPTION for cHsrpExtSecAddrEntry, a
primary address must exist before a secondary address for
the same {ifIndex, cHsrpGrpNumber} pair can be created. IpAddress .1.3.6.1.4.1.9.9.107.1.1.2.1.1 |
cHsrpExtSecAddrRowStatusThe control that allows modification, creation, and deletion
of entries. For detailed rules see the DESCRIPTION for

cHsrpExtIfTableHSRP-specific configurations for each physical interface. SEQUENCE OF CHsrpExtIfEntry .1.3.6.1.4.1.9.9.107.1.2.1 |
cHsrpExtIfEntryIf HSRP entries on this interface must use the BIA (Burned
In Address), there must be an entry for the interface in this
table. Entries of this table are only accessible if HSRP has
been enabled i.e entries can not be created if HSRP is not
enabled. Also, the interfaces should be of IEEE 802 ones
(Ethernet, Token Ring, FDDI,VLAN, LANE, TR-LANE).
Setting cHsrpExtIfRowStatus to active initiates the
entry with default value for cHsrpExtIfUseBIA as FALSE.
The value of cHsrpExtIfRowStatus may be set to destroy
at any time. If the row is not initiated, it is similar to
having cHsrpExtIfUseBIA as FALSE.
Entries may not be created via SNMP without explicitly setting
cHsrpExtIfRowStatus to either 'createAndGo' or 'createAndWait'.
Entries can be created and modified via the management
protocol or by the device's local management interface.
If the row is not active, and a local management interface
command modifies that row, the row may transition to active
state.
A row which is not in active state will timeout after a
configurable period (five minutes by default). This timeout
period can be changed by setting cHsrpConfigTimeout. CHsrpExtIfEntry .1.3.6.1.4.1.9.9.107.1.2.1.1 |
cHsrpExtIfUseBIAIf set to TRUE, the HSRP Group MAC Address for all groups
on this interface will be the burned-in-address. Otherwise,
this will be determined by ciscoHsrpGroupNumber. In case of
sub-interfaces, UseBIA applies to all sub-interfaces on an
interface and to all groups on those sub-interfaces.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.107.1.2.1.1.1 |
