Hi Julxu,

I think you can use cacti with snmp for network information polling. Even you can monitor individual devices as well.

Here is one example from our network.

I have a software, and it support both snmp and cdp. since we are heavy user for cisco catalyt switches, on both layer2 and layer3.

I would like to know, which protocal will make less load on local switch, speciallycat6500.

Many Regards

Hi Julie,

Looks like Snmp is recommended over cdp

1       Disable CDP on ports that connect to partner companies through an extranet, or to nodes in the network that have no need for data provided by CDP. The data provided by CDP could prove useful to a malicious user.

2 Use SNMPv3 with MD5 authentication and DES encryption

Please check this lik http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/best/practices/recommendations.html#wp1130860

See section 3.5.
