CAMMER(1) User Contributed Perl Documentation CAMMER(1) NNAAMMEE cammer - list switch ports with associated IP-addresses SSYYNNOOPPSSIISS cammer [--arp=comunity@router] [--verbose] community@switch DDEESSCCRRIIPPTTIIOONN CCaammmmeerr is a script which polls a switch is able to query a switch for its ethernet to port asignements. If a source of ip2mac mappings is provided as well, it will resolve the ethernet addresses too. Cammer will use the machines local arp cache as well as the the _/_v_a_r_/_l_i_b_/_d_h_c_p_3_/_d_h_c_p_d_._l_e_a_s_e_s file to resolve etherent addresses If you have a router, the router might know a lot about mac2ip mapping. Use --arp=comunity@router to query the router for its arp table. We found that running something like nmap --host-timeout 2s -sP 192.168.0.0/24 (as user!) helps to populate the local arp cache.
