Migrating from CSS 11503 to ACE ??

[michaelnolan]

Hi there,

I'm currently in the process of looking at migrating from CSS to ACE.

I'm looking for some advise on a suitable equivalent ACE model that matches what I have today.

Currently I have a CSS 11503 which I don't believe is heavy utilized, is there a way I can check this on the CSS, what throughput is been used?

Any advise would be much appreciated.

Regards,

Michael.

I recently did this using the following:

1) Use an SNMP package to track the utilization of the CSS ports from the switch side

2) Use an SNMP package to track the utilization of the CSS ports from the CSS itself (should match switch side)

3) Use an SNMP package to track the number of TCP Connections on the CSS (using svcExt.mib on the CSS)

4) Manually determine the number of SSL connections using the following from the CLI

a. Clear the counters

b. Wait a period of X

c. Issue the following:

CSS11503-2(debug)# sho ssl statistics | grep conn

0 Handshake started for incoming SSL connections

0 Handshake completed for incoming SSL connections

0 Handshake started for outgoing SSL connections

0 Handshake completed for outgoing SSL connections

0 TCP connections failed

0 TCP connections established

0 TCP connections originated

0 TCP connections terminated

The SSL connections per second would be a sum of the completed SSL handshakes completed divided by the period of X.

This would give us accurate sizing information.
