The redundancy mode of a card.
The redundancy mode of a card is part of the state of
the redundancy machine (i.e., the hardware or software
that implements redundancy). The redundancy modes of
all the cards in a redundancy group together represent
the state of the redundancy machine for that
redundancy group. The inputs to the redundancy machine
that cause the redundancy mode of a card to transition
from one value to another are events like card
failure, card removal, user configuration, etc.
Objects defined using this TC have a MAX-ACCESS of
read-write or read-create. This allows a user to force
the redundancy machine to transition to a desired
The following values may be written:
active(1) - Make this card an active member of the
standby(2) - Make this card a standby member of
the redundancy group.
unused(3) - Do not use this card.
Writing the above values may cause a switchover.
When read, the values mean:
active(1) - This card is an active member of the
standby(2) - This card is a standby member of the
unused(3) - This card is not being used at present.
notPresent(4) - There is no card in the slot.
A value that identifies a physical slot in the
For a chassis with slots that are numbered left to
right, the leftmost slot has value 1.
For a chassis with slots that are numbered top to
bottom, the topmost slot has value 1.
This MIB allows management of redundancy of CPU and
switch cards for the Catalyst 8540 switch, and other
products with similar implementations.
The Catalyst 8540 is an ATM switch. It has 13 (or, in
some models, 14) slots, of which 2 slots can hold CPU
cards, and 3 (or, in some models, 4) slots can hold
switch cards. A switch card is one that contains the
ATM switching fabric. Two switch cards are combined
to operate in 20Gbps switching mode.
For CPU cards, 1+1 redundancy is supported.
For switch cards, 2+1 redundancy is supported.
The device's running-configuration and
startup-configuration both reside on the active CPU
card. This object indicates whether these
configurations should be copied from the active CPU
to the standby CPU whenever they change. It is
acceptable to copy either, both, or neither.
This object is used to allow or disallow the
execution of the enable exec command on the
When set to 'true', the enable exec command can be
executed on secondary CPU, and the user may enter
enable mode after keying in the password configured.
When set to 'false', the enable exec command cannot
be executed; thus, no user may enter enabled mode.
This object is used to force the synchronization of
counters from primary CPU to secondary CPU. It should
generally be set just before a controlled Route
When this object is retrieved, the value 'noop' is
returned. When this object is set to 'noop' no
operation is performed.
This object configures the synchronization of ATM

When this object is set to 'true', sychronization
is enabled. When this object is set to 'false',
synchronization is disabled.
The desired switching capacity (i.e., bandwidth) of
the switch fabric.
tenGbps(1) - 10 Gigabits/sec
twentyGbps(2) - 20 Gigabits/sec
If the value configured by writing to this object is
supported by the device, it will be applied at the
next reboot. The speed at which the switch fabric is
currently operating is reflected by the value of
