I was wondering if cisco provides any software for free download to undertake basic monitoring of Cisco router interfaces for keeping a tab on my WAN links (when they go up or down) and can give me an average view of bandwidth available across them for SLA purposes.
Am I asking for too much? How do you guys take care of this? I would rather live with something that utilises SNMP traps than configure netflows. Aren't SNMP traps better than netflows, performance wise?
My routers are 1800 and 2800 series and running a bandwidth of 100 mbps between them. I have admin control on all these.
