Tasks
-

Configure the devices according to the topology to achieve these goals:

1. Configure a SPAN session on SW01 using these parameters:
• Session Number: 20
• Source Interface: VLAN 99
• Traffic Direction: Transmitted Traffic
• Destination Interface: Ethernet 0/1
2. Configure the NetFlow Top Talkers feature for outbound traffic on interface E0/2 of R01 with these parameters:
• Number of Top Talkers: 50
• Sort Type: Packets
• Cache Timeout: 30 seconds
3. Configure an IP SLA operation on SW02 and start the ICMP probe with these parameters:
• Entry Number: 10
• Target IP: 1.1.1.1
• Source IP: 172.16.2.2
• Frequency: 5 seconds
• Threshold: 250 milliseconds
• Timeout: 3000 milliseconds

At the second part 2. Configure the NetFlow Top Talkers feature for outbound traffic on interface E0/2 of R01 with these parameters: • Number of Top Talkers: 50 • Sort Type: Packets • Cache Timeout: 30 seconds There is something missing - the last part of cache timeout. Correct output as below: R01 config t interface et0/2 ip flow egress ip flow-top-talkers top 50 sort-by packets cache-timeout 30000 <- that is missing wr mem

in the 2nd config, I added by mistake ip flow ingress please ignore that as the question is only looking for outbound traffic

and also the cache-timeout is based on millisecs so instead of 30 it should be 30000

For first part: E0/1 is part of port-channel 1 If we configure the same port as destination interface of a SPAN session that port will go into "monitoring" mode and would show as down in port-channel 1 The destination port in SPAN session should be some other port. It does not make sense.

I agree with 123robinsong and I am not sure if exiting the intf eth0/1 with the cmd ip flow egress will bind it with the rest of cmds in global config..Maybe Yes. see the http://www.bscottrandall.com/9.7.3.html R1(config)# ip flow-top-talkers R1(config-flow-top-talkers)#? Netflow top talker configuration commands: cache-timeout Configure cache timeout default Set a command to its defaults exit Exit from top talkers configuration mode match Configure match criteria no Negate a command or set its defaults sort-by Configure top talker sort criteria top Configure number of top talkers =======there is a match cmd ========= So I would go with this: ip flow-top-talkers top 50 sort-by packets cache-timeout 30000 match output-interface Ethernet0/2 is this the same as tempaccount..sugests?

For the first section (SPAN) , I think this is the correct configuration: monitor session 20 source vlan 99 tx (You can choose between a phisical interface or a vlan NOT an interface vlan) monitor session 20 destination interface ethernet 0/1 write memory or (It depends on the OS you are using): monitor session 20 source vlan 99 tx destination interface ethernet 0/1 write memory

So we mirror the traffic of the VLAN to Ethernet0/1 which is part of a Port channel and on the other side connected to a switchport. Khhmm. Realistic :-)

When it says "Configure the devices according to the topology to achieve these goals", does it include setting up things like routing, etherchannel and whatnot? Or is the topology already built, complete and operational, and we only need to do specifically what is being asked under Tasks?

Topology is already configured. Apply only the configuration you are asked for.

Correct configuration should be ip sla 10 icmp-echo 1.1.1.1 source-ip 172.16.2.2 threshold 250 timeout 3000 frequency 5 ip sla schedule 10 life forever start-time now Keep in mind that "ip sla schedule 10 ..." is a separate command that activates the SLA. Furthermore do not forget to append "start-time" otherwise the scheduler does not start.

I encountered a problem when performing the first task, SPAN in my lab in CML. Under "monitor session 20 source... or source interface...", I do not have the option for "interface vlan...". The solution suggests to use "interface vlan 99" as the source. However, only the commands "source vlan..." or "source interface GigabitEthernet... or Port-channel..." are given in the IOS that I am using. I read about this topic, and "interface vlan..." does not seem to be offered as the source in the SPAN configuration generally. SW01(config)#monitor session 20 source ? interface SPAN source interface remote SPAN source Remote vlan SPAN source VLAN SW01(config)#monitor session 20 source interface ? GigabitEthernet GigabitEthernet IEEE 802.3z Port-channel Ethernet Channel of interfaces Did someone successfully test the solution?

This is what I can set in my lab: SW01(config)#monitor session 20 source vlan 99 tx

I tried it on a 3750 and 3850 and the "interface vlan" option was missing. You can only choose between interface or vlan.Not 100% sure if it's a limitation by the emulators I am using (including my hardware as well) or it should be that way. I guess the latter one.
