lan switching

[prashantrecon]

I have 6506 switch to which 2950 switch is connected.

To 2950 a server is connected is there any easy method to track the ip of that server from 2950 switch.

If so please mention the steps.

Hi Kumar,

Try: show ip arp | include (insert MAC here); that will output the IP address.

You need to run the command "sh ip arp" on the 6500 switch because that will be the switch which does the routing for the server vlan.

The 2950 will only have the mac-address of the server in the cam table.

Hi

My concern is on 2950 switch when i run the command show mac-address table it will display atleast 30 to 40 macaddress

so for that on 6550 i hav to run show ip arp | include macaddress

so for 30 macaddress i have run the command everytime

First of all I"m assuming this server has a static IP? Second, the way I usually track down IPs is as follows.

1. First I do a ping x.x.x.x (where x.x.x.x is the ip adddress)

2. Then I do a 'show arp | i x.x.x.x' (This will show me the Mac Address of the IP that I just ran a ping on)

3. Then I do a 'show mac address-table | i xxxx.xxxx.xxxx (Where xxxx is the MAC Address)

That should tell you to which port and vlan it's on.

Hi John,

My concern is on 2950 switch to the port fa0/5 a server is connected.

And 2950 is connected to 6506 .

I want know the ip address of server which is on fa0/5

I donot have the permission to log into server

You could ping the subnet broadcast address for that subnet which in turn will ping that address. You could then

run a 'show mac address-table' to see what the MAC address of that port is and then a 'show arp | i (mac address).

When you run the 'show mac-address table'  you will see a bunch of mac addresses unless you use an include statement

with the specific mac address.
