Viewing Routing Statistics

Viewing Routing Table Entries

Display entries in the routing table by using the show routes command. The routing table displays IP layer information about the destination, mask, TOS, gateway, flags, reference count, use, interface, and protocol information.

ORACLE# show routes
Destination/Pfx    Gateway         Flags    RefCnt Use     Proto Tos I/f
0.0.0.0/0          172.30.0.1      2010003  0      0           1   0 wancom0
10.0.0.0/16        172.30.0.1      2010003  1      0           1   0 wancom0
10.0.200.164       172.30.0.1      2020007  1      13801       2   0 wancom0
127.0.0.1          127.0.0.1       2200005  82     36220       2   0 lo0
172.30.0.0/16      172.30.55.127   2000101  2      0           2   0 wancom0

Viewing Routing Stats

Display statistics for the application layer routes shown in the routing table by using the show route-stats command.

ORACLE# show route-stats
routing:
        0 bad routing redirect
        3 dynamically created route
        1 new gateway due to redirects
        9 destinations found unreachable
        2 use of a wildcard route

Testing Routing Policies

Use the test policy command to test application layer routes from the ACLI by specifying a from and to address. You can also specify a source realm, time of day, and carriers.

The test-policy command works similarly to the way a configuration element does. This command allows you to test and display local policy routes from the ACLI by specifying From and To addresses. After you have entered these addresses, use the show command to perform the actual lookup.

ORACLE# test-policy ?
carriers                      sets list of permitted carriers
from-address                  From address list
media-profiles                list of media profiles
show                          shows local policy test results
source-realm                  Source realm
time-of-day                   enables/disables time of day
to-address                    To address
exit                          end test

The following table lists the test-policy specification formats.

Specification	Format
source-realm	A string that indicates the name set in the source-realm field of a configured local-policy element. If you enter a “*” in this specification, any configured source realms will be matched. An empty source-realm value indicates that only the global realm will be tested
time-of-day	A Boolean value that can be set to either enabled or disabled that indicates whether or not to use the time of day value set in the start-time and end-time fields set in configured local-policy elements
carriers	A list of comma-separated text strings enclosed in quotation marks of the names of permitted carriers set in the carriers fields set in configured local-policy elements.

Test Policy Subcommands

The following table lists and describes the test-policy subcommands.

test-policy Subcommand	Description
from-address	Set the From address of the local policy you want to look up/test. From addresses should be entered as SIP-URLs (e.g., sip:19785551212@netnetsystem.com).
to-address	Set the To address of the local policy you want to look up/test. To addresses should be entered as SIP-URLs (for example, sip:19785551212@netnetsystem.com).
show	Performs the actual policy lookup and shows the next hop and the associated carrier information for all routes matching the From and To addresses entered.
exit	Exits the test-policy session.

Testing Address Translations

Oracle Communications Session Border Controller number translation is used to change a Layer-5 endpoint name according to prescribed rules. Number translations can be performed on both the inbound and the outbound call legs independently, before and after routing occurs. Number translation is used for SIP, H.323, and SIP/H.323 interworking configurations.

ORACLE# test-translation
called-address                called address
calling-address               calling address
show                          shows local translation test results
translation-id                Translation Id
exit                          end test

Test Translation Limitations

Although you can use the test-translation command to test the address translation feature, you can only use it for rules configured with specific input-header-type and output-header-type values. Applicable rules include those configured with the called-header or calling-header values for both the input and output header type.

You cannot use test-translation to test translation-rules configured with the following input-header-type and output-header-type values:

called-address-or-number
called-extension
called-phone-context
calling-address-or-number
calling-extension
calling-name
calling-phone-context
history-info-header
isup-called-party-number
isup-calling-party-number
isup-generic-number
isup-original-called-number
isup-redirect-number
none
p-asserted-id-header
redirect-address-or-number
redirect-header request-uri

Viewing QoS Based Routing Statistics

You can view statistics about QoS based routing for realms, and see what realms are in service or whether a call load reduction has been applied. In the ACLI show realms display, the following values show you QoS based routing information:

QoS Major Exceeded
QoS Critical Exceeded
QoS R-Factor Avg.

You can see these statistics in the following example of a show realm display:

ORACLE# show realm
