Help finding a port on switch!

[raghavbhardwaj]

Hi All,

My organization's network engineer has asked me to find out the port number which is connected to GigabitEthernet 3/0/2 & GigabitEthernet 4/0/9 respectively. I don't know out of 48 port on switch in our data center which one are these two (both port are on different switches). Please help me how I can I find them.

Thanks,
Raghav

Hi,

Not sure what type of switch you are using.  If this is a stack of 3750 switches, 3/0/2 means the 3rd switch port 2 and 4/0/9 means 4th switch port 9. The ports are usually organized from left to right when you are facing the switch.

Hi Raghav,

I think below commands can help you in this situation.

1. Find the MAC address & VLAN ID by using the command

“SWITCH# show mac address-table interface Gi1/0/6”

2. Then Find the IP address by using the command

“CORESWITCH# show ip arp vlan <VLAN ID> | include <MAC ADD>”

“CORESWITCH# show ip arp vlan 20 | include 4437.e64c.0aed”

3. Then open the Command Prompt Run -> cmd

4. Find the Host name by using the command

"C:\Users\Administrator>nbtstat -a 10.0.2.8"

Please Find the attachment for detailed explanation.
