Hello,

Need more information on your interface configuration and other end device connected to this interface.

The following link provides description for the above output ( "show interface" command )

Hello i already see the above links but information is useless, it just inform the same what is in output.

firewall interface is connected to 2970 switch and switch port is an access port, there is no vlan configured on firewall port.

ask me what other information you need

Please provide output of

"show interface " from the 2970 switch and "show interface" from pix

find the attachment

Hello Muhammad,

Compared the bytes transmitted and received by both interfaces.It seems that description is dropped vlan packets is not indicative of correct packet drops as stated by following cosmetic bug

CSCeh81141

Dropped VLAN untagged packet

To observe where actually packets gets dropped use the command ""show asp drop""

Find the attached files, actually i am getting connection time out, some times not usually, my web server is on inside and it try to connect with a DB at outside 90% is success rate and 10% is failure ip address is as following

webserver 87.200.2.6

PG 195.229.85.91 destination port is 2443

see the syslog file

Hi,

The connection is established from outisde to this IP address on various ports and sometimes it Resets the connection request immediately whereas in some instances the application

closes the connection by sending FIN after few minutes.

The set of messages are well explained in the following link

http://www.cisco.com/en/US/docs/security/asa/asa72/system/message/logmsgs.html

show asp drop

http://www.cisco.com/en/US/docs/security/asa/asa72/command/reference/s2_72.html#wp1174636

There can be many reasons for the tcp packet drops.You can start with application configuration on 87.200.2.6 and who is initiating the connection.

Depending upon the observed time-frame and traffic pattern,this can be totally normal.
