I want to collect "Rejected IP" + "Rejected Port" from problematic X350.
Is possible get this information with snmp or other method?
Additional Q: if I create ACL to deny unwanted subnet on "Rejected port", Is this deny connection count only on 'show access-list counter' or included also in "Rejected IP" and "Rejected Port" (read: show iparp stats vlan all) ?
I got many rejected counts and because I want start debug collect it to start debug my network incorrect design.
excuse about my bad English and networking knowledge...
You can allow ARP packets having a sender address within a network subnet configured and deny everything else. You would see ACL deny counter increasing but not see the rejected counter increasing in the show iparp output.
entry 1 { if { arp-sender-address 10.0.0.0/24; } then { permit; } }
entry 2 { if { arp-sender-address 0.0.0.0/0; } then { deny; count denyarp; } }
