Hi all,
I have a problem with a connection to the server, under normal conditions ping from the PC monitor to the server normally. but sometimes there is a failure that resulted in the PC unable to connect to the server.
If I do change the IP address on the PC monitor, Ping goes back to normal or I do service network restart on the server problem is gone. please help me, im stuck at this moment
see the attachment for topology:

Habibi

but sometimes there is a failure that resulted in the PC unable to connect to the server.
Can you provide more details in terms of what the failure actually is ?
In addition, are the switches (sw3/sw4) L3 switches ie. what device is the 192.168.10.254 configured on ?

Hi Jon
Initially the pc monitor can ping the server, and vice versa. in some time these devices can not be connected.
sw3 & sw4 is L2 switches, 192.168.10.254 is FW ASA as a Gateway.
thx for your response

Hello,
Expecting that all of the devices have the right subnet-mask then traffic should not reach the Firewall. Traffic should stay on the L2 domain.
That being said:
- Do the PC and Server have the IP address configured statically or is via DHCP?
Next time the issue happens Check
- Try to ping the Firewall from the PC and Server
- Check the ARP table of the PC/Server
- Interface status of the switches
sh interfaces fastEthernet x/x switchport
- Any Err-disabled problem
sh interfaces fastEthernet x/x status err-disabled
- The MAC address table of the switches
show mac address-table interface fastEthernet x/x (Make sure you see the MAC address of the PC/Server on the right ports)
Hope this helps,
