If I have a wireless AP has its uplink (with fixed IP) connected to the SRX firewall interface fe-0/0/1. Is that possible to find out this AP IP address in SRX CLI?
-> show interfaces terse | match xe-4/0/0
-> show configuration | match xe-4/0/0 | display set | display inheritance
or you need to know remote IP:
-> show arp interface ge-1/1/0.0

Sorry for the late reply. But the method of "show interface | match" and "show arp" were not work. There is no result show.
Check out the below discussion to find the ip address of the device connected to an interface
Hope this helps
Thanks. But the topic you suggest to me seems not apply to my case. Even none of the reply was mark as solution.
1. Ping the broadcast IP in the subnet on your interface. I would expect all hosts in the subnet reply something.
2. Ping the IP in the subnet one by one
Does the AP support LLDP? you can try enabling LLDP for that interface , wait for some time then do :
show lldp neighbors interface ge-x/y/z
I hope this help! , let me know your results.
what do you see in the output of show interfaces terse | match fe-0/0/1
what is the configuration of interface fe-0/0/1 ?
show arp no-resolve interface fe-0/0/1 can be helpful.
( AP has IP address on it so i would assume that Fe-0/0/1 and that AP are in same subnet ? )
