connection limits on ASA

we have an ASA 5520 & 5540. my understanding says the connection limit on 5520 is around 120000 connections.Please correct if this is wrong.

got certain doubts on connection limits:

- does this mean limit on tcp or udp or both

- what happens if it exceeds the limt, drops the connections or hangs the firewall

- any way to check what is the max limit and the current usage on the firewall

Thanks in advance!

Re: connection limits on ASA

For ASA 5520, the maximum connections are 280,000 (inc. all traffic).

To check for the current connections: show conn count

Here is the specs on ASA series:

Hope that helps.
