Good day,

What model switch is this?

Ans: That is dell 3448

What revision of firmware is the switch at?

Ans:

SW version    2.0.0.34 ( date  25-Jul-2010 time  14:24:24 )

Boot version    1.0.1.01 ( date  15-Jun-2006 time  11:42:56 )

HW version    00.00.01

What type of device is associated with this MAC address? Is it plugged into port 25? Have you tried the command leaving the ethernet e25 left off?

Ans:

That is a server and plugged to port 25.  It can shown its learned MAC address when using command

show bridge address-table

Thanks!

Yes. that IP and MAC also owned by server and connected to Ethernet e25 directly.

It is not possible to run the command you advise.

console(config)# arp 120.120.133.1 84:EF:2D:0A:6C:1F ethernet 1/e25

% bad parameter value

Can be learned by

console# show bridge address-table ethernet e25

Aging time is 300 sec

 Vlan        Mac Address       Port     Type

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

  1       84:2b:2b:0a:6b:1f    e25    dynamic

is it related to vlan 1 setting, because the ip address of vlan 1 is set to different subnet

interface vlan 1

ip address 192.168.168.201 255.255.255.0

thanks!

Hello,

I have done a some config which is added 120.120.133.100 into vlan 1.  It will learn some other some

# show arp

ARP timeout: 60000 Seconds

 VLAN    Interface     IP address        HW address          status

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

vlan 1     e1         192.168.168.200  00:78:51:9d:50:bb   dynamic

vlan 1                 192.168.168.211  00:1F:51:01:d2:22   dynamic

vlan 1     e1         120.120.133.13    00:34:dd:0b:a1:07   dynamic

However it still can learn e25 information.

But after I ping 120.120.133.100 - vlan 1 IP..  It can learn the arp information

# show arp

ARP timeout: 60000 Seconds

 VLAN    Interface     IP address        HW address          status

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

vlan 1     e1         192.168.168.200  00:78:51:9d:50:bb   dynamic

vlan 1                 192.168.168.211  00:1F:51:01:d2:22   dynamic

vlan 1     e1         120.120.133.13    00:34:dd:0b:a1:07   dynamic

vlan 1     e25      120.120.133.1       84:EF:2D:0A:6C:1F  dynamic

Did you know why?
