I have just put in a ASA 5510 and since I put it in, my Internet connection has really slowed down alot. Anyone know why this might be? I had a check point firewall in before, and had no issues at all. I was wondering if anyone else experienced this?
Use the show blocks command.
The show blocks command helps to determine if the security appliance is overloaded. This command lists the pre-allocated system buffer utilization. A full memory condition is not a problem as long as traffic moves through the security appliance. Issue the show conn command in order to see if the traffic moves. If the traffic does not move and the memory is full, there can be a problem.
This information can also be viewed through the Simple Network Management Protocol (SNMP).
The information shown in a security context includes the system-wide information as well as context-specific information about the blocks in use and the high water mark for block usage.
This is a sample output from the show blocks command in single mode:
SIZE MAX LOW CNT
4 1600 1598 1599
80 400 398 399
256 3600 3540 3542
1550 4716 3177 3184
16384 10 10 10
2048 1000 1000 1000
In order to resolve this issue, download and upgrade PIX/ASA to software version 7.2.2 (18) or later from Cisco Downloads. If issue still exists contact Cisco Technical Support.
