  • Configuring Span port 6509

    I want to configure a span or rspan port on my 6509, to find the culprit of our network latency. We have several other switches connected to the 6509 by fiber.

    Would I use span or rspan? Can someone help me properly configure this? Does it disrupt network traffic at all when configuring (meaning any outages?)

    Thanks.

    and what do you want to span?

      I want to span the traffic from all other switches that are connected (or I guess trunked) to the 6509, to 1 port on the 6509. It would be from a certain VLAN.

        I'm guessing that will bog my network down even more, by mirroring all traffic from all other switches, to the 6509...if it's possible. I don't want to do it that way, if that's the case.

        Here are the commands I found, I've already setup the rspan vlan, which has been VTP'd to all other switches:

        Configure the RSPAN vlan:
        Code:
        set vlan 500 rspan
        Specify VLAN 200 as a source VLAN for RSPAN VLAN 500 (on all switches???):
        Code:
        set rspan source 200 500
        Configure RSPAN destination ports (only on 6509???):
        Code:
        set rspan destination 3/1 500
        Am I in the right direction?

          We realized it would be much easier if we just created a 1 span session on the 6509, to span the internal interface of our firewall.
