Preset attributes are similar to characteristics, in that their
values control the way in which the routing module operates.
However, unlike characteristics, you cannot alter preset
attribute values using the set command.
NOTE
These characteristics are preset attributes. They should
only be set by an expert.
o broadcast lsp transmission interval
Support: L1,L2
Default: 33 Value: 1-65535
Interval, in milliseconds, between the transmission of Link State
Packets (LSPs) on a broadcast circuit.
o complete snp interval
Support: L1,L2
Default: 10 Value: 1-600
Interval, in seconds, between generation of Complete Sequence
Number Packets (SNPs) by a designated router on a broadcast
circuit.
o default es hello timer
Support: All
Default: 600 Value: 1-65535
Value to be used for the current suggested Hello timer, in the
absence of any suggested value from the intermediate system (IS).
On routers, this is the value to be suggested when the router is
not required to poll the ES configuration. In routers, this value
is suggested by the Suggested ES Configuration Timer option in IS
Hellos.
o dr isis hello timer
Support: L1,L2
Default: 1 Value: 1-65535
Interval, in seconds, between the generation of IS-IS Hello PDUs
by the designated router.
o es cache holding time
Support: End
Default: 600 Value: 1-65535
Holding time, in seconds, for an entry in the node's end-node
cache database.
o es cache width
Support: End
Default: 3 Value for Tru64 UNIX: 1-4294967295
Default: 3 Value for OpenVMS: 1-65535
Maximum number of LAN address entries in the node's end-node
cache database on a broadcast circuit.
o holding multiplier
Support: All
Default: 3 Value: 2-63
Value by which to multiply the Hello timer to obtain the holding
timer value for ES and IS Hellos and for point-to-point, router-
to-router Hellos.
o inactive selector
Support: All
Default: 33 Value: 2-255
This is the selector value identifying the port to which incoming
Inactive Subset PDUs are to be sent.
o initialization timer
Support: All
Default: 6 Value: 1-63
Delay, in seconds, between initialization of a data link and
sending a DECnet-Plus message on a DDCMP circuit.
o isis format
Support: L1,L2
Default: 0 (ISO) Value: (ISO) or 1 (DNA Private)
This attribute controls the protocol identification to be
used for "DNA Private" PDUs. On broadcast circuits, this
characteristic also controls the SAP on which they are
transmitted.
o isis holding multiplier
Support: L1,L2
Default: 10 Value: 2-63
Value by which to multiply the ISIS Hello timer to obtain the
value of the holding timer for LAN level 1 and level 2 router-to-
router Hellos.
o maximum age
Support: L1,L2
Default: 1200 Value: 1-65535
Number of seconds before an LSP is considered to be expired.
o maximum lsp generation interval
Support: L1,L2
Default: 900 Value: 60-900
Maximum interval, in seconds, between link state packets (LSPs)
generated by this node.
o minimum lsp generation interval
Support: L1,L2
Default: 30 Value: 1-65535
Minimum time, in seconds, between generation of LSPs by this
node.
o minimum lsp transmission interval
Support: L1,L2
Default: 5 Value: 5-30
Minimum interval, in seconds, between retransmissions of an LSP.
o multicircuit es hello timer
Support: End
Default: 10 Value: 1-65535
Value to be used for the current suggested Hello timer on a
multicircuit end node with more than one circuit enabled, in
the absence of any suggested values from the IS.
o originating L1 lsp buffer size
Support: L1,L2
Default: 1492 Value: 128-1492
Maximum size of level 1 LSPs and SNPs originated at this node.
o originating L2 lsp buffer size
Support: L2
Default: 1492 Value: 128-1492
Maximum size of level 2 LSPs and SNPs originated at this node.
o partial snp interval
Support: L1,L2
Default: 2 Value: 1-65535
Minimum interval, in seconds, between sending partial SNPs.
o poll es hello rate
Support: All
Default: 50 Value: 1-65535
Interval, in seconds, between ES Hellos when a router requires to
poll the ES configuration.
o queue threshold
Support: L1,L2
Default: 1 Value: 1-63
Average queue length at a router, above which the "congestion
experienced" bit will be set in a forwarded data PDU.
o waiting time
Support: L1,L2
Default: 60 Value: 1-65535
Delay, in seconds, between routing databases being in the waiting
state and entering the on state.
o zero age lifetime
Support: L1,L2
Default: 60 Value: 1-65535
Time, in seconds, for which the purge header of an expired LSP is
retained.
