<p class="MsoNormal">Hey guys,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> We have an issue what seems to be mostly on 3560/3750 and older 4500 switches. We have not had the issue at all on any phone connected to our 4510s with Sup-7 engines. At random when the phone/client is already connected to the switch,
the port goes into err-disable. The ports are in single host mode.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Security violation on the interface GigabitEthernet0/23, new MAC address (0021.70c8.58cb) is seen.AuditSessionID Unassigned<o:p></o:p></p>
<p class="MsoNormal">security-violation error detected on Gi0/23, putting Gi0/23 in err-disable state<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The switch seems to be treating the phone like a new DATA client.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">TAC seems to think possibly the phone is not transmitting CDP long enough that the switch puts the phone mac address into the DATA group and when it does, it err-disables the port.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anyone else seen this happen with firmware version SCCP 9.3.1.1 on 7962 model phones?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
