Hello,
The scenario is as follows: NXOS 9.3.7 I am converting some code that manages a network to support NX-OS.
config:
vlan 133
int vlan 133
ip address 192.168.1.1/29
show ip arp vlan 133 shows:
IP ARP Table
Total number of entries: 5
Address Age MAC Address Interface Flags
192.168.1.2 00:01:43 0cc4.xxxx.xxxx Vlan133
IOS and a lot of other networking operating systems would've also shown:
Internet 192.168.1.1 - 000f.f8a0.xxxx ARPA vlan 133
I don't really care what it does in the CLI because nobody looks at this in the CLI, the problem this is causing me is that I can no longer figure out which of the IPs on the VLAN belong to the router itself (instead of hosts connected to the router). I need an SNMP OID I can pull that includes the router's own ARP information.
I have also confirmed that RFC1213-MIB::ipNetToMediaPhysAddress.ifIndex..of..vlan..133 only shows host/client ARP and not the router's SELF entry.
How do I find the router's SELF entry for VLAN 133 via SNMP?? This is critical.
