Monitoring Interfaces and VLANs in ONE session?

[roadrunner992]

Hello,

how can I monitor Interfaces and VLANs in one Monitor Session?

Problem is, that this monitored traffic needs to be send to ONE single destination port, what is not allowed to do with 2 seperate monitor sessions.

So my general problem is:

port 1 nees to be monitored

vlans 1,2,3 needs to be monitored

all traffic needs to be sent to

port 2

how can i do this?

hardware that i tried on and need a solution

1  WS-C3850-12S 03.07.00E cat3k_caa-universalk9 INSTALL

2 cisco WS-C4500X-32 cat4500e-universalk9.SPA.03.09.02.E.152-5.E2.bin

Thanks for help!

 - If you talk about monitoring traffic from the destinations that you mention then check : https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/configuration/guide/cli/CLIConfigurationGuide/Span.pdf

I know this type of session configuration. but on the given devices, its not possible its quite different to this:

xxxxxxxxxxxx(config)#monitor session 1
% Incomplete command.

You cannot jump in a special monior menu

you need to add the whole command:

xxxxxxxxxxxxxxx(config)#monitor session 1 source vlan 1
% Cannot add VLANs as sources for SPAN session 1

This message coming up because i already entered:

xxxxxxxxxxx(config)#monitor session 1 source interface gixxx

its not possible to add int and vlan on one session on these devices

I belive that is Limitation as per the information and device you have mentioned :

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/16-3/configuration_guide/b_163_consolidated_3850_cg/b_162_consolidated_3850_cg_chapter_01000101.html

May be to look alternative how we can achieve, need more information below :

port 1 nees to be monitored   - is ths Trunk or access port ?

vlans 1,2,3 needs to be monitored  - is this Layer 3 Interfaces ?

If you have Trunk Interface can be achived with VLAN filter in that config (you can refer above document)

[roadrunner992]

port 1 - yes is a trunk

vlans 1,2,3 yes layer 3 with definated subnets

the port 1 is a uplink interface, the vlans are present on that switches and are routed over thes switches(core)

is there another image, we can install to get these functions, ineed?

[roadrunner992]

any1 can help? do we need a new stich model or can we use another licence/software version?

[balaji.bandi]

If the port 1 Trunk have all the VLAN passing, you can use filter to get all information and destination port to port2

look at the example config the URL i have provided.

The problem is,

the vlan traffic is internal and not only on this port.
