Here is a snippet from an old script I had to get the snmp stats and current
RSVP reservation.
This first OID .1.3.6.1.4.1.2636.3.2.3.1.1 you walk and it returns the names
and dynamic OIDs of the ingress LSPs. The $1 awk returns is the specific OID
associated with an LSP.
snmpbulkwalk -v2c -Oan -c $comm $router .1.3.6.1.4.1.2636.3.2.3.1.1 | awk
'{sub(/^.1.3.6.1.4.1.2636.3.2.3.1.1/, "");print $1}'
my $lsp_bytes_oid = ".1.3.6.1.4.1.2636.3.2.3.1.3";
my $lsp_bw_oid = "1.3.6.1.4.1.2636.3.2.3.1.21";
Those are the two OIDs where the second one is for the RSVP reservation. In
order to get the value you'll have to concatenate the OIDs from the first one
onto the second one. As an example if I have an LSP from the first one with a
returned value of:
.78.69.80.54.68.83.82.74.48.50.45.78.69.80.54.66.80.82.74.48.49.45.49.45.66.69.0.0.0.0.0.0
You can get the current RSVP reservation with the full OID
1.3.6.1.4.1.2636.3.2.3.1.21.78.69.80.54.68.83.82.74.48.50.45.78.69.80.54.66.80.82.74.48.49.45.49.45.66.69.0.0.0.0.0.0
snmpget -v2c -Oan -c mycommunity 10.4.6.26
.1.3.6.1.4.1.2636.3.2.3.1.21.78.69.80.54.68.83.82.74.48.50.45.78.69.80.54.66.80.82.74.48.49.45.49.45.66.69.0.0.0.0.0.0
.1.3.6.1.4.1.2636.3.2.3.1.21.78.69.80.54.68.83.82.74.48.50.45.78.69.80.54.66.80.82.74.48.49.45.49.45.66.69.0.0.0.0.0.0
= INTEGER: 1000
The value returned is in Kbps.
The first OID grabs the current byte stats from the LSP but it's not reliable,
there are points where the value will reset to 0 and you don't really know when
it's going to be. Another way to get the data is via Junosscript. You can use
this call:
$jnx->get_mpls_lsp_information(ingress => "1", detail => "1", statistics =>
"1"); It will return all the information you need, you just have to scrape
the data from the returned output.
