IpArp not learning IP

Hi,

i am trying to troubleshoot why IPARP is not showing the IP addresses of edge devices.
Slot-1 SEDUCA050100.3 # sh iparp stats ports 3:23
IP ARP Port Statistics Thu Mar 8 08:55:47 2018
Port Link State Active ARP Total Dynamic Static
===============================================================================
3:23 A 0 0 0
===============================================================================If i do a "sh fdb port 3:23" i can see the mac of the connected device, but for some reason IPARP is not storing the Mac and the IP address of the connected device, this is hapenning on all ports, also and since IPARP doest not store any IP addresses, IdMgr doesnt show them too.

I have all vlan interfaces configured with an ip address and IPARP is enabled by default on the switch.

I wondering what commands can i use to troubleshoot this situation.

I missed that in my first read too.

So what switches and code versions are we talking about. If its not the obvious it might be a bug that needs to be reported.

Are the devices getting IPs?
What is the output of [show ip arp]
Or [show ip arp port 3:23]

You said "IPARP is not showing the IP addresses of edge devices." does that mean you see the upstream switch IPS?

Hi Yakimenko,

Thank you for the info, but has i said on my original post i have all vlan interfaces configured with an ip address.
