Enabling traps for remote-shelf events
When you have configured a
trap
profile to generate a trap protocol data unit (PDU)
on detection of a certain event, if the event occurs, the system sends a PDU to a
specified SNMP station. For hosted systems, the host sends trap PDUs generated by
any shelf in the system. For background information about traps, see the
Stinger
Administration Guide
.
Trap optimization
To streamline the number of traps generated by remote shelves, you can enable trap
optimization. Trap optimization behavior depends on the settings of the following
parameters, shown with default values:
[in TRAP/""]
trap-optimization-enabled = no
slot-enabled = no
linkdown-enabled = yes
linkup-enabled = yes
ascend-link-down-trap-enabled = no
ascend-link-up-trap-enabled = no
To fully enable trap optimization, set all these fields to
yes
. For example:
HOST>
read trap dsl-snmp
HOST>
set trap-optimization-enabled = yes
HOST>
set slot-enabled = yes
HOST>
set ascend-link-down-trap-enabled = yes
HOST>
set ascend-link-up-trap-enabled = yes
HOST>
write -f
The following trap optimizations are made:
■
LinkUp and LinkDown traps are not generated unless
ascend-link-down-trap-
enabled
and
ascend-link-up-trap-enabled
are set to
no
.
■
AscendLinkUp traps are not generated in the case of slots coming up and system
reset. In these cases, the ascendLinkUp trap will not be sent for 120 seconds after
the slot comes up.
■
AscendLinkDown traps are not generated in the case of slots going down.
■
The sysSlotStateChange trap is generated only for the slot status changes to
operStateDown or operStateUp. The trap is not sent for other intermediate states
such as operStateLoading and operStatePost.
■
If
trap-optimization-enabled
is set to
yes
but
slot-enabled
is set to
no
, the
system generates ascendLinkDown and ascendLinkUp traps for each line when a
slot changes state, and does not generate the sysSlotStateChange trap.
Modified traps to include shelf numbers
Several traps have been modified to include the value of the shelf number along with
the slot index for events such as a card reset, slot state change, system clock change,
flash state change, CAC failure, or ATM OAM loopback time-out. In addition, new
traps have been introduced for events and state changes on remote shelves.
