HI Brandon.   We have tried that and get the following error:   No log handling enabled - turning on stderr logging snmpwalk: Authentication failure (incorrect password, community or key)   it’s not happy about the \ in the password.   Is it possible to get a Webex with someone to look at the issue?   Thanks   ...

When using a special character in the password we get the following message from snmpwalk.  " No log handling enabled - turning on stderr logging Error: passphrase chosen is below the length requirements of the USM (min=8). snmpwalk:  (The supplied password length is too short.) Error generating a key (Ku) from the supplied authentication pass phrase."   It seem as though snmpwalk doesn’t recognise the special character     On a test device if we change the password so that it contains no special character the snmpwalk runs without any issues. To save us from changing the snmp password is there anything that can be done? ... View more

On Further investigation we believe it may be due to the use of special characters in the SNMPv3 password. Can anybody confirm if there are any issues with the use of special characters for SNMPv3? ... View more

Is it possible to send the capture directly to an external source instead of saving it on the CUCM? I have around 5 phones suffering very intermittent silent audio and am just concerned that the logs will fill the CUCM disk quickly.   Secondly can you capture from select phones at once or is it one or all?   Thanks  ...

Thanks Stephen. Please see the response below from TAC.  "As discussed on the call, while associated to SSID you need to perform authentication, either with PSK or dot1x or web-auth (depends on security settings). With PSK and dot1x SSIDs generally no client intervention is needed and process happens transparently as credentials are stored in PC supplicant profile. With web-auth SSID you can connect and obtain IP address but then you are redirected to web portal for logon. When AP moves from one channel to another clients that are associated with it losing network connection, go to scan mode and connect with other SSID, that results in old session termination and establishing new session. In case of dot1x/PSK clients credentials are supplied automatically on re-authentication, however with web-auth SSID client re-associates to SSID but is moved to WEBAUTH_REQ state so every time you are redirected to login portal when you are session is terminated. I can't provide you link to CCO documentation as I wasn't able to find that process clearly mentioned." We have already increased the session timeout to its max as a trial but the same issue is being experienced. The TAC engineer has asked for the DCA timers and anchor time to be increased as a next step to a resolution. Thanks ... View more
