I am currently facing the problem that Cisco Prime Infrastructure v3.6.0 can not access my Cisco switches over SSHv2 when scheduling a job. We used to have Catalyst C2960X Switches with the software version 15.2(2)E6. Since we changed all of the switches to new Catalyst C9200L ones with the software version 16.11.1, the problem occurs. The SSH keys on the switches are already set to 2048 as in another discussion mentioned. Prime can reach the switches with ICMP and vice versa. As i can see, SNMP is also not working now. I for sure double checked the credentials in the credential profiles and also tried accessing the switches with PuTTY and the same credentials successfully.
Is there any explanation why this is happening? As shown in the device support table for PI36, the 9200 series should be supported.
- Can you access the particular switches with manual-ssh ? Also, when you say credentials are correct , could you remove a problematic device from Prime and then re-add but press button Verify Credentials first, to make sure that all credentials are working for Prime (?)
