I am looking at several Network monitoring solutions ( Zabbix, Zenoss, Cacti and such, and most can use SNMP to report.

Currently the Cisco switches are not configured for reporting, what do I need to do to configure them for Network monitoring software to get the ability to monitor them? I am looking for both status, and bandwidth monitoring capability.

I am looking to configure two 1841's, a ASA 5500, a 1721, a 3750, three 3560's, and six 2950's.

I would prefer to do this without taking them down, and if they need to come down, I woujld have to do it on a weekend or late night.

Thanks
 
If the switch supports it, just enable snmp enter your community string, then setup your monitoring app (could use nagios) snmp monitoring is really not that hard to do
 
SNMP is easy as pie.

"snmp-server community communitynamehere ro"

Thats all you need, unless your management box needs to write to the cisco device, then use "rw" instead of "ro".
 
Great, just for kicks, what are you guys using for network management for your Cisco switches?


Thanks
 
We use Solarwinds Orion. I've played around with Cacti, its pretty good too.
 
RTG but we also need it to be quite accurate for billing purposes. Cacti and MRTG should both be suitable for most circumstances. I have used Zabbix as well and liked it myself.
 
Netflow can also be a useful tool, and can be configured without taking down the devices.
 
I use a combination of services. The primary is Solarwinds, which just happens to be one of the best monitoring suites I've used (expensive though, wow). On top of that I use Zenoss which is pretty nice. It has some pretty features and is nice for "at a glance" network status reports.

Aside from that I have all my network devices dump their logs to a linux syslog server (php-syslog-ng to be specific).

So far I havent' found a single piece of software that does everything I want it to, which is too bad. Solarwinds, however, comes really close.
 
ASA 5500 is just a newer PIX. Same PIX command structure. Just look it up on CCO.

Something like
Code: 
snmp-server community <string>

Because its a firewall thought, you might need to also allow it out the appropriate interface.
