If you are adding/modifying/removing any command or utility script, please also make sure to add/modify/remove any unit tests from the tests directory as appropriate. If you are modifying or removing an existing 'show', 'config' or 'sonic-clear' subcommand, or you are adding a new subcommand, please make sure you also update the Command Line Reference Guide (doc/Command-Reference.md) to reflect your changes. Please provide the following information: --> #### What I did Update `show bfd summary` to aggregate BFD sessions across all ASIC namespaces when no `-n <namespace>` is provided. Extend multi-ASIC BFD tests and expected output for the all-ASIC summary. #### How I did it #### How to verify it Run the `show bfd summary` with the change can give you all BFD sessions across all ASIC namespaces. BTW, running the classic `sudo ip netns exec <namespace> show bfd summary` will still give you the BFD sessions of that namespace, so there's no regression ``` admin@dut:~$ sudo ip netns exec asic1 show bfd summary Total number of BFD sessions: 220 Peer Addr Interface Vrf State Type Local Addr TX Interval RX Interval Multiplier Multihop Local Discriminator ----------------------------- ----------- ------- ------- ------------ ----------------------------- ------------- ------------- ------------ ---------- --------------------- 2603:10b0:607:7:0:a:eb64:8700 default default Up async_active 2603:10b0:607:7:0:a:eb64:8b00 50 50 3 false 127 2603:10b0:607:7:0:a:eb62:8900 default default Up async_active 2603:10b0:607:7:0:a:eb62:8b00 50 50 3 false 104 2603:10b0:607:7:0:a:eb64:8300 default default Up async_active 2603:10b0:607:7:0:a:eb64:8b00 50 50 3 false 211 10.235.96.10 default default Up async_active 10.235.96.8 50 50 3 false 18 10.235.96.138 default default Up async_active 10.235.96.139 50 50 3 false 25 2603:10b0:607:7:0:a:eb62:c00 default default Up async_active 2603:10b0:607:7:0:a:eb62:800 50 50 3 false 108 2603:10b0:607:7:0:a:eb60:8700 default default Up async_active 2603:10b0:607:7:0:a:eb60:8b00 50 50 3 false 73 2603:10b0:607:7:0:a:eb61:8c00 default default Up async_active 2603:10b0:607:7:0:a:eb61:8b00 50 50 3 false 93 ... ``` #### Previous command output (if the output of a command-line utility has changed) ``` admin@dut:~$ show bfd summary Total number of BFD sessions: 0 Peer Addr Interface Vrf State Type Local Addr TX Interval RX Interval Multiplier Multihop Local Discriminator ----------- ----------- ----- ------- ------ ------------ ------------- ------------- ------------ ---------- --------------------- ``` #### New command output (if the output of a command-line utility has changed) ``` admin@dut:~$ show bfd summary Total number of BFD sessions: 660 Peer Addr Interface Vrf State Type Local Addr TX Interval RX Interval Multiplier Multihop Local Discriminator ------------------- ----------- ------- ------- ------------ ------------------- ------------- ------------- ------------ ---------- --------------------- 20.0.13.6 default default Up async_active 20.0.13.1 50 50 3 false 27 2603:10e2:400:2::7 default default Up async_active 2603:10e2:400:2::1 50 50 3 false 106 20.0.12.6 default default Up async_active 20.0.12.1 50 50 3 false 136 2603:10e2:400:14::9 default default Up async_active 2603:10e2:400:14::1 50 50 3 false 94 2603:10e2:400:6::5 default default Up async_active 2603:10e2:400:6::1 50 50 3 false 159 2603:10e2:400:14::7 default default Up async_active 2603:10e2:400:14::1 50 50 3 false 92 2603:10e2:400:11::8 default default Up async_active 2603:10e2:400:11::1 50 50 3 false 73 20.0.10.9 default default Up async_active 20.0.10.1 50 50 3 false 11 20.0.10.3 default default Up async_active 20.0.10.1 50 50 3 false 132 20.0.5.2 default default Up async_active 20.0.5.1 50 50 3 false 143 20.0.11.7 default default Up async_active 20.0.11.1 50 50 3 false 15 2603:10e2:400:1::2 default default Up async_active 2603:10e2:400:1::1 50 50 3 false 155 20.0.13.3 default default Up async_active 20.0.13.1 50 50 3 false 137 2603:10e2:400:14::2 default default Up async_active 2603:10e2:400:14::1 50 50 3 false 89 20.0.1.9 default default Up async_active 20.0.1.1 50 50 3 false 5 20.0.5.5 default default Up async_active 20.0.5.1 50 50 3 false 145 2603:10e2:400:5::3 default default Up async_active 2603:10e2:400:5::1 50 50 3 false 158 20.0.14.6 default default Up async_active 20.0.14.1 50 50 3 false 33 ... ``` Signed-off-by: Sonic Build Admin <sonicbld@microsoft.com>
