PTSEs
Key entities in PNNI are PNNI Topology State Elements (PTSEs). PTSEs are a collection of PNNI
information that is flooded to all logical nodes within a peer group. Each node_0 creates its own PTSEs
called
self originated PTSEs, of which there are 6 types:
Nodal State Parameter (NSP)
Nodal Information Group (NIG)
Internal Reachability (IR)
External Reachability (ER)
Horizontal Link (HL)
Up Link (UL).
Summary information about these PTSEs can be obtained by issuing the following command:
à
ð
8265ATM
>
show pnni ptse self_originated all
á
ñ
This lists the number of existing PTSEs of each type. If the summary shows the presence of, for example,
3 HL PTSEs, you can use a positive integer, smaller or equal to 3, to retrieve detailed information about
the respectively indexed HL PTSE. Say, for example, you wish to inspect the second PTSE, then you
would enter the following command:
à
ð
8265ATM
>
show pnni ptse self_originated horizontal_link 2
á
ñ
The general structure of the command applies to all other PTSE types, you simply replace
horizontal_link
by
nodal_information_group
,
internal_reachability
,
external reachability
,
nodal_state_parameters
, or
up_link
.
Additionally, you can also display the PTSE's Resource Availability Information Groups (RAIGS) by
including the parameter
with_raigs
. For example:
à
ð
8265ATM
>
show pnni ptse self_originated horizontal_link 2 with_raigs
á
ñ
You can also limit the PTSE summary information displayed to only one type of self originated PTSE. For
example, entering:
à
ð
8265ATM
>
show pnni ptse self_originated horizontal_link
á
ñ
will display summary information about HL PTSEs only.
