Previous Behavior: In releases prior to 2021.02.3, multiple set of entries for IMSI, MSISDN, and IMEI were displayed as an output of show subscriber command.

Old sample output:

["key:imsi-123456789012348",
"imei:123456786666660",
"imsi:123456789012348",
"msisdn:223310101010101",
"id-index:1:1:33587200",
"id-value:2051",

]

New Behavior: In 2021.02.3 and later releases, only single set of entries for IMSI, MSISDN, and IMEI is displayed. MSISDN display is changed to from msisdn: <msisdn_number> to msisdn:msisdn-<msisdn_number>.

The following show commands display single set of entries for IMSI, MSISDN, and IMEI.

show subscriber all
show subscriber namespace sgw all
show subscriber nf-service sgw all

Important

MSISDN display is not changed for the following command:

show subscriber namespace sgw imsi <imsi_value> full command

New sample output:
