I have an ASA 5505 that I am using SNMP Traffic sensor on and I am monitoring mulptile interfaces on that ASA. One of them is giving me an error that says Could not Identify Port Number. The other interfaces are working fine. I have no idea why this is doing this. Any ideas?
Have you tried to recreate the sensor? Also, please try to scan the interfaces with the SNMP Tester and see if the port number looks correct. If not, you may want to restart SNMP on the Cisco.
I have rebooted the ASA already. I have also tried to recreate the sensor.
Whats weird is I am able to monitor 3 other interfaces on the ASA but the one I need to monitor the most is the one that gives the error.
Please send us the results of the SNMP test to email@example.com and we can see what may be the issue. It could be the naming that is used for the interface.
So I just renamed the interface description and recreated the sensor and now it worked. Go figure.
Would it be possible to post what the name was before and after for anyone who has a similar issue? Thanks!
Not sure if the name has anything to do with it...
interface Ethernet0/0 description ***CXN to ISP*** ! interface Ethernet0/1 description ***CXN to 2821 Router G0/1*** switchport trunk native vlan 2 switchport mode trunk
Here is the config on 2 of the interfaces. E0/0 was the problem one while E0/1 has not had any issues.
I updated the E0/0 to be:
interface Ethernet0/0 description Comcast ISP ! interface Ethernet0/1 description ***CXN to 2821 Router G0/1*** switchport trunk native vlan 2 switchport mode trunk
And left E0/1 the way it was. I recreated the sensor and then it worked without an issue.
Thanks so much for the information! Hopefully it will help others if they have similar issues.
