I’ve recently upgraded our Cisco FWSM to 4.1(2) and noticed that they now support access to the arp table via snmp.
Eg. snmpwalk -Os -c public -v 1 <FWSM> ipNetToPhysicalTable
ipNetToPhysicalPhysAddress.259.ipv4."127.0.0.51" = STRING: 0:0:15:0:0:0
etc
What would be involved in getting arpnip to support this?
I am running the latest versions:-
Netdisco Version : 1.0
SNMP::Info Version : 2.01
Net-SNMP Version : 5.04021
Perl Version : 5.8.9
It does get detected as the right device:-
SNMP::Info::device_type() layers:00000100 id:9 sysDescr:"Cisco Firewall Services Module Version 4.1(2)"
Device Type : SNMP::Info::Layer3::Cisco
But it appears to only look at the following values:-
SNMP::Info::_load_attr at_paddr : ipNetToMediaPhysAddress
SNMP::Info::_load_attr old_at_paddr : atPhysAddress
SNMP::Info::_load_attr at_netaddr : ipNetToMediaNetAddress
SNMP::Info::_load_attr old_at_netaddr : atNetAddress
What’s in involved in adding ipNetToPhysicalPhysAddress ?
As a reference in the OID tree it is
. iso (1) . org (3) . dod (6) . internet (1) . mgmt (2) . mib-2 (1) . ip (4)
|
- -- ipNetToPhysicalTable (35)
|
- -- ipNetToPhysicalEntry (1)
|
| -- ipNetToPhysicalIfIndex (1)
|
| -- ipNetToPhysicalNetAddressType (2)
|
| -- ipNetToPhysicalNetAddress (3)
|
| -- ipNetToPhysicalPhysAddress (4)
|
| -- ipNetToPhysicalLastUpdated (5)
|
| -- ipNetToPhysicalType (6)
|
| -- ipNetToPhysicalState (7)
|
| -- ipNetToPhysicalRowStatus (8)
Happy to assist in any way to progress this.
Regards,
Jukka
