The current way of printing subscriber, connection, and transaction
info is ugly (sorry) and has several problems:
- the terminal width should be large enough to fit quite long lines,
otherwise the output is unreadable and looks misaligned;
- some fields (such as subscriber name) can be larger than it's
expected, so either they're getting truncated, or again, the
output is misaligned and unreadable;
- adding new info fields would require one to think about the
alignment and would make the output even more cumbersome.
Here is an example output of 'show connection' command:
_Subscriber_______________________________________ _LAC_ _RAN___________________ _MSC-A_state_________ _MSC-A_use_
IMSI-123456789012345:MSISDN-12345:TMSI-0x12345678 1 GERAN-A-4294967295:A5-3 WAIT_CLASSMARK_UPDATE 2=cm_service,trans_cc
IMSI-123456789012356:MSISDN-234567:TMSI-0x123ABC78 65535 UTRAN-Iu-4294967295 COMMUNICATING 2=cm_service,trans_sms
IMSI-262073993158656:MSISDN-123456:TMSI-0x493026BA 1 GERAN-A-1 MSC_A_ST_COMMUNICATING 1=1 (silent_call)
Another 'show subscriber' command mixes the information about
subscriber, its connections and transactions without any alignment,
what also decreases the readability.
This change introduces a hierarchical approach, based on the old
'field per line' formatting. First of all, the VTY commands were
extended with optional flags:
show connection [trans]
show subscriber cache [(conn|trans|conn+trans)]
show subscriber TYPE ID [(conn|trans|conn+trans)]
so it can be decided, whether to print child connections and/or
transaction, or not. For example:
show connection trans
would print all connections and their child transactions with
hierarchical alignment:
Connection #00:
Subscriber: IMSI-262073993158656:MSISDN-123456:TMSI-0x76760B75
RAN connection: GERAN-A-1
RAN connection state: MSC_A_ST_COMMUNICATING
LAC / cell ID: 1 / 0
Use count total: 1
Use count: 1 (silent_call)
Transaction #00:
Unique (global) identifier: 0x00000000
GSM 04.07 identifier (MT): 0
Type: silent-call
another example is:
show subscriber cache conn+trans
which would print all known subscribers,
their active connections and transactions:
Subscriber #00:
MSISDN: 123456
LAC / cell ID: 1 / 0
RAN type: GERAN-A
IMSI: 262073993158656
TMSI: 76760B75
...
Connection:
RAN connection: GERAN-A-1
RAN connection state: MSC_A_ST_COMMUNICATING
...
Transaction #00:
Unique (global) identifier: 0x00000000
GSM 04.07 identifier (MT): 0
Type: silent-call
Transaction #01:
Unique (global) identifier: 0x00000001
GSM 04.07 identifier (MO): 0
Type: SMS
Transaction #02:
Unique (global) identifier: 0x00000002
GSM 04.07 identifier (MT): 0
Type: SMS
Please note that we don't print redundant info in child nodes
(i.e. connection and transaction info), such as subscriber name
in connection info, nor connection name in transaction info - it
is clear from the hierarchical formatting.
