Hi,
I have EXOS switches (440-G2, 620, 590) and XMC Analytics (VMware virtual appliance). I have little experience with collecting information for analytics, but I’ve started using/looking into XMC Analytics (we’ve been using XMC Management and Control for some time). Regarding analytics and sFlow from my switches I’m struggling a little. According to analytics it looks like I’m supposed to use 2 interfaces, where eth0 = management and eth1 = tap. When I use this setup, I don’t seem to receive flow information from the switches. I’m also not sure if Jumbo-frames/ip-mtu must be enabled and if I’ve done that correctly. Also, should the mirrored interfaces on the switches belong to a totally separated vlan or is it OK to use the user-defined management vlan (e.g. distribute a global vlan to all switches for mirror only).
In addition we have a remote site and I’m wondering if Jumbo-frames/ip-mtu will work through the firewall/cloud (we’re using an IPsec tunnel between sites).
I’ve attached a limited drawing, describing the principal setup of our sites. What I would like to know is:
- What would be the preferred setup for the local site switches in regards to vlan (ipaddress?), jumbo/ip-mtu, global/common separated vlan only for mirror traffic, through firewall
- What would be the preferred setup for the remote site switches (same questions as above)
- Are there any special requirements on the VMware hosts/nic’s in regards to the analytics appliance?
I’ve used EXOS switches for quite some time and I’m pretty familiar with the commands, so I won’t need a detailed config-setup. I would just like som information regarding best practice for local/remote sites in regards to sflow and setup.
Thanks in advance for any pointers.
