    How about the device IP address?

     

    I know the device mac, connected to juniper port 0/0/1. How do i know the IP address of the device? (which is static)

    You could probably use a protocol that maps and IP to a mac address.

    The command show arp will also display the ip address.  But the switch needs ot have a layer 3 interface in that vlan for those to be present.  If the gateway is on an SRX then show arp there will display the mac along with the ip address.
