SG300 CLI show arp [interface-id] returns Bad parameter value

I'm trying to examine the ARP table on specific phy ports on a SG300 switch.  The Cisco CLI guide shows this syntax:

show arp [ip-address ip-address] [mac-address mac-address] [interface-id]

Using the CLI and the "?" key to get assistance, I'm not successful:

switch3#show arp                  

  configuration        Display ARP related configuration

  ip-address           Filter ARP show by IP

  mac-address          Filter ARP show by MAC

  GigabitEthernet      IEEE 802.3 Gigabit Ethernet port id

  GE                   IEEE 802.3 Gigabit Ethernet port id

  Port-Channel         Valid Port-Channel interface.

   <CR>

switch3#show arp GigabitEthernet

  <1-1>  GigabitEthernet device number ; 0 for slot.

switch3#show arp GigabitEthernet 1/ 

  <0-0>  GigabitEthernet slot number

switch3#show arp GigabitEthernet 1/0/

  <1-52>  GigabitEthernet port number

switch3#show arp GigabitEthernet 1/0/1

% bad parameter value

switch3#show arp GigabitEthernet 1/0/4

% bad parameter value


switch3#show version

SW version    1.2.7.76 ( date  19-Jul-2012 time  17:54:43 )

Boot version    1.1.0.6 ( date  11-May-2011 time  18:31:00 )

HW version    V02

I don't have http server enabled, I prefer SSH and CLI to do my work.  What am I doing wrong?

Layer 2 devices don't typically maintain ARP tables. They have bridge tables. Show mac address-table would be the correct command in the layer 2 environment.

It seems to prefer simply "giX" for the interface ID.  However, even with that, I'm not seeing any mac entries on ports that are up and actually have connections:

switch3#show interfaces status gi1

                                             Flow Link          Back   Mdix

Port     Type         Duplex  Speed Neg      ctrl State       Pressure Mode

-------- ------------ ------  ----- -------- ---- ----------- -------- -------

gi1      1G-Copper    Full    1000  Enabled  Off  Up          Disabled On    

switch3#show arp gi1

Total number of entries: 1

  VLAN    Interface     IP address        HW address          status     

--------------------- --------------- ------------------- ---------------

Yes, in the end the mac address table is what I wanted.  Thanks for your help!
