TenGigE0/7/0/56 is up, line protocol is up
Conditions
+ only affects PAT linecards
Workaround
For the power you can use the DOM command and see if you good TX/RX power.
=> n = logical slice number [0,1,2,3]
=> p = 15 port number corresponding to the slice. Specify in HEX 0-E
=> P = speed 1= 10G
[sysadminnvm:0_1:~]$ slice_driver_client_test_cli -Q -n2 -p1 -P1
cmds entered = 4, last cmd = 0, speed = 1 slices = 2
Connect Ok, now wait.....
test_cli_connect_cb for BAO Driver via CAPI.
Client connection to Slice Driver ok, hdl=0x20f5310
HDL Match!!!!
Send CAPI message for test command 20
