Cisco IPSLA over VLANs
Posted on 2009-06-29
Picture a 'Metro Ethernet' network, multi-site, built from Switches. The network uses VLANs to segregate and prioritise traffic - 802.1q.
I need to monitor delay across this network, using IPSLA. Here's the tricky part : the requirement is to send those IPSLA tests *across specific VLANs* so that the reported delay is representative for the traffic in those VLANs.
Would a dedicated Cisco (router or switch) at each measurement point, connected into the cloud with an 802.1q segment, do this ? For example, initiate IPSLA tests from different IP source addresses, and then get the Cisco to route tests from a given IP onto a given VLAN and on into the cloud ? This needs to be done via SNMP, by the way - not the CLI.
Comments or Requests for more info welcome.
