Alcatel Unleashed

Hi,
I'm new with networking. We have an omniswitch 6850 and want an inventory of the network components connected to this switch.

With the commando show interfaces status i know which port is online.
With the commando show mac-address-table i know which mac address is connected on the ports.

For computers I can retrieve the ip by nbtstat - a <<mac-address>>. Some other components are medical apparatuses and this doesn't work.

Is it possible to know the ip addresses connected to the switch?

Kind regards,
Andy

You can try "show arp" but this will only work properly if the switch is routing for those boxes.

You could also use LLDP but I have some doubts if the medical equipment supports this kind of stuff already.

With 6.3.1, you can set up sflow to sample traffic on all ports and send it to a collector. Watch it long enough, and you should get a good idea of what systems are flowing traffic through that switch

sflow receiver 1 name collector address a.b.c.d
sflow sampler 1 port-range receiver 1 rate 512 sample-hdr-size 128
sflow poller 1 port-range receiver 1 interval 30
