I know CISCO 6509 is an old device, but as it happened to me to work on it today and I found no useful information in internet to solve my issue, maybe this post could help someone else
I connected a network device to a 6509 , port 4/8 and but then how to connect to it without the IP address? (ok I solved looking into the dhcp server, but then I found the cisco way)
1. show the MAC address connected to the port
sh cam dynamic | include 4/8
this was the result:
1 00-0a-b6-55-56-10 4/8 [ALL]
2. go to the Multilayer module (in my case is the module 15, use: sh module to check it)
session 15
3. display arp table filtering by the mac found at point 1 (pay attention, the format is different!)
sh arp | include 000e.b678.5620
the result:
Protocol Address Age Hardware address Type Interface
Internet 10.0.0.55 45 000a.b655.5610 ARPA Vlan1
we just found the IP address of our device -> 10.0.0.55
