[afnog] Discover IPs Connected to Cisco Switch

[Eliufoo C. Mahinda]

Hi Dan,
thanks for the feedback.
It a L2 switch. However, the method for show mac-add and show ip arp command will require me to track and associate individual mac address to a IP address.
That can do this automatically?

This depends on the kind of switch you have.

A L2 switch does not have any knowledge of IPs (so you wont be able to
see the IP's connected to the switch)

In this case use the mac address table (sh mac-add) to discover all the
mac connected the the switch

The use the arp table of the terminating L3 device to resolve the IP to mac.
