Summary1943: Issue with ios15ShortenIfName_real
DescriptionWhen trying to pull SNMP sync (SNMP Generic Sync), if using ios15ShortenIfName_real for retrieving ifName it returns blank/null. If I edit the remote.php, and change in $shorten_by_breed 'ios15' => 'ios12ShortenIfName_real', it works. I have experienced this with multiple ios 15.x devices, whether switches or routers, all return no ifName using ios15ShortenifName, but all work using ios12ShortenifName.
Steps To ReproduceSNMP Generic Sync of ios 15.x device. = ifName returns blank/null, text box to manually enter.
change in remote.php, $shorten_by_breed 'ios15' => 'ios12ShortenIfName_real'
SNMP Generic Sync of ios 15.x device. = ifName returns populated
TagsNo tags attached.

Could you add the following details?
* the device sysObjectID and hardware model as shown in RackTables dictionary
* ifName and ifDescr for the ports that do not work as expected out of the box

Hello,

So on the two installations I am dealing with here's some of the devices (this issue covered multiple devices and IOS 15 revisions) this was experienced with:

166 Cisco Catalyst 2960G-48TC-L
50481 Cisco Catalyst 6509
147 Cisco Catalyst 4948
377 Cisco Catalyst 4948-10GE
188 Cisco Catalyst 3750G-12S
50491 Cisco ASR 1002-X

As for ifName and ifDesc:

This was happening with any interface (FastEthernet, GigabitEthernet, Vlan, Port-Channel), but here are some examples of ifName & ifDescr:

If this is not the information you need, please let me know and I'll try to get you the details you require. If you need me to test I have a test environment that is separate from my production with a single IOS15 device on it, but my production environment has several switches and routers that are running various IOS15 variants.

Thanks,
Robert Maxwell
