Symptom
FTD sensor may display the following symptoms when the user executes any "show" command that extends past the pager length, locking the LINA prompt until either the command execution is finished or aborted.
When in this condition the sensor may display or result on:
1. Policy deployments pushed from FMC to fail
2. CLISH commands after some time to slow respond or to never display any output
3. FMC to report the sensor as offline because of #2
Conditions
If a user utilizes terminal pager on the LINA CLI (e.g. "terminal pager X" after connecting to "system support diagnostic-cli" prompt) and in conjunction with any "show" commands that output data longer than the terminal pager would allow (e.g. indicated by the output) this in turn forces LINA prompt to be on the locked scenario (example below):
firepower# terminal pager 2
firepower# show running-config
: Saved
:
<<<<<<<<<<<<<
Workaround
Abort (hitting "q") or finish the command in execution locking LINA
