-- This MIB provides an extension to the CISCO-HSRP-MIB which defines Cisco's
-- "proprietary Hot Standby Routing Protocol (HSRP), defined in RFC2281. The
-- extensions cover assigning of secondary HSRP ip addresses, modifying an
-- HSRP Group's priority by tracking the operational status of interfaces,
-- etc.-- Terminology:
-- HSRP is a protocol used amoung a group of routers for the purpose of
-- selecting an "active router" and a "standby router".-- An "active router" is the router of choice for routing packets.-- A "standby router" is a router that takes over the routing duties
-- when an active router fails, or when preset conditions have been met.-- An "HSRP group" or a "standby group" is a set of routers which communicate
-- using HSRP. An HSRP group has a group MAC address and a group IP address.
-- These are the designated addresses. The active router assumes
-- (i.e. inherits) these group addresses.-- BIA stands for Burned In Address.CISCO-HSRP-EXT-MIB DEFINITIONS::=BEGINIMPORTSMODULE-IDENTITY,OBJECT-TYPE,IpAddressFROM SNMPv2-SMI

HSRP group."::={ cHsrpExtGroup 1}cHsrpExtIfTrackedEntry OBJECT-TYPESYNTAX CHsrpExtIfTrackedEntry
MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"The 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."INDEX{ ifIndex, cHsrpGrpNumber, cHsrpExtIfTracked }::={ cHsrpExtIfTrackedTable 1}

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."DEFVAL{0}::={ cHsrpExtIfTrackedEntry 2}cHsrpExtIfTrackedRowStatus OBJECT-TYPESYNTAXRowStatusMAX-ACCESSread-createSTATUScurrentDESCRIPTION"The control that allows modification, creation, and deletion

Addresses per interface and group."::={ cHsrpExtGroup 2}cHsrpExtSecAddrEntry OBJECT-TYPESYNTAX CHsrpExtSecAddrEntry
MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"The 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."INDEX{ ifIndex, cHsrpGrpNumber, cHsrpExtSecAddrAddress }::={ cHsrpExtSecAddrTable 1}

MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"If 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
