I have different Cisco switches (Catalyst, Nexus) configured and working mostly, but for some (random) interfaces SNMP Traffic sensor returns error "Could not identify port number". PRTG version 15.2.16.2229+ . Is there a way to fix this?
Article Comments
yes (but I have tried manual ("keep names..") also without success), currently:
Port Name Update:Automatic sensor name update if name changes in device Port Identification:Automatic (recommended) Start and end port = 0

Hi,
do the said ports have unique identifiers such as ifAlias or ifName? If so, have you tried using one of them explicitly?
Best regards

hi,
it turns out that, if device configuration contains in Description string "->" (minus and greater_than), then sometimes it breaks something inside PRTG (but in most cases not)

to be precise, previous response was relevant to Catalyst only, for Nexus it (PRTG) seems to not like symbol "/" (slash) in Description of port configuration.

Hi,
Just an update for you. Our testing team has identified the issue which is a bug indeed. A development ticket has been opened and a fix should be available with an upcoming version.
As a workaround, please do not use ifDescriptions with said symbols.
