Monitor aux ports through SNMP

[howardtopher]

Is it possible to see the aux ports on a PA-5200 series firewall through the SNMP interface mib?  These are currently the interfaces that show up, the aux ports are not there.  This is on 9.1.11, PA-5250 to be specific.

ifName.1 = STRING: ha1-a
ifName.2 = STRING: ha1-b
ifName.3 = STRING: hsci
ifName.4 = STRING: mgmt
ifName.5 = STRING: ethernet1/1

ifName.7 = STRING: ethernet1/3
ifName.8 = STRING: ethernet1/4
ifName.9 = STRING: ethernet1/5
ifName.10 = STRING: ethernet1/6
ifName.11 = STRING: ethernet1/7

Thank you for posting question @howardtopher

Could you go to Device > Setup > Aux-1 / Aux-2 and make sure that these interfaces are enabled? In order the Aux-1 / Aux-2 interfaces to be enabled the IP setting has to be configured. After this, please run SNMP Walk again.

Kind Regards

I have aux-1 enabled because that's the one I'm using.  I don't need aux-2 so it's not enabled.  The snmp walk that I ran was after enabling aux-1.  I ran it again just to be double sure, and aux-1 is not there.

Thank you for reply @howardtopher 

I see, thank you for confirmation. I have PA-5260 running 9.1.5 (AUX-1 is not in use). I was doing some research on this to find out more.

The AUX-1 port is referred as eth5.

cfg.aux_intf.map: { 'aux-1': eth5, 'aux-2': eth6, }

net.s0.eth5.cfg: { 'disable-dhcp': True, 'fips-gated': True, 'hwaddr': 08:66:1f:02:7d:e2, 'ifindex': 7, 'ip-type': static, 'mtu': 1500, 'onboot': True, 'routes': { 'default': , }, 'table': aux-1, 'v6routes': { 'default': , }, }
net.s0.eth5.dhcp-dns: { }
net.s0.eth5.dhcp-ntp: { }
net.s0.eth5.dhcp-opcmd: 0
net.s0.eth5.dhcp-options: { }
net.s0.eth5.hwcfg: { 'advertised': [ ], 'link': Down, 'mode': Force, 'setting': 1Gb/s-full, }
net.s0.eth5.stats: { 'rx-bytes': 0, 'rx-compressed': 0, 'rx-drop': 0, 'rx-errs': 0, 'rx-fifo': 0, 'rx-frame': 0, 'rx-multicast': 0, 'rx-packets': 0, 'tx-bytes': 0, 'tx-carrier': 0, 'tx-colls': 0, 'tx-compressed': 0, 'tx-drop': 0, 'tx-errs': 0, 'tx-fifo': 0, 'tx-packets': 0, }

eth5 can be identified by Interface Index: 'ifindex': 7. By doing SNMP walk, I could see this interface to be showing up:

I know this is not perfect answer to your question, but if your monitoring system can monitor 'ifindex': 7, the it should be possible to monitor this interafce.

Kind Regards

Interesting.  I checked the same commands on my firewall and it also shows ifindex 7.  However, when I do the snmpwalk or look in the monitoring system, ifindex 7 shows up as ethernet1/3.  It also shows "admin down" and "no connector", which is correct for ethernet1/3 as I'm not using it.  It's really strange. 🙂
